Earthquake Cause and Effect Essay Sample

Earthquakes are one of the worst and deadliest natural disasters that can occur. They are due to different factors and leave behind after-effects in their wake. An earthquake is the sudden release of strain energy in the crust of the planet’s surface, which will result in shaking that resonates outwards from the source. Simply, it is the sudden shaking of the Earth’s surface and can also be called a quake, tremor, or tremblor.

Earthquakes come in different sizes, as some are weak and cannot be felt, while others are violent and can destroy cities. The frequency, size, and type of quakes experienced are called seismicity. Earthquakes can be a result of volcanic action too. Furthermore, they have various effects that disturb lives and property.

The Valdivia Earthquake, also known as the Great Chilean, is the most powerful earthquake ever recorded. It occurred on the 22 nd of May, 1960, with studies placing it between 9.4 and 9.6 on the moment magnitude scale. The main cause of the quake was tension released by the Nazca plate under the South American plate. The earthquake lasted for about 10 minutes and resulted in tsunamis that affected Hawaii, southern Chile, eastern New Zealand, the Aleutian Islands, Japan, southeast Australia, and the Philippines.

Earthquakes are one of the most destructive and fascinating natural disasters that can cause a huge amount of destruction, injuries, and even death, but what makes them so dangerous? In this earthquake cause and effect essay sample, we will attempt to answer this question and explore why earthquakes occur and what effects they can have on society and the environment. Earthquakes are caused by sudden movement of the earth’s crust resulting from a release of energy from the Earth’s interior, and can be triggered by many different things including human activities such as mining and construction. Understanding the processes behind earthquakes can help individuals and organizations make better plans for future mitigation and adaptation if an earthquake were to occur. Additionally, students can buy a coursework to learn how to plan for an earthquake and develop better understanding of how to prepare for and cope with natural disasters.

Causes of Earthquakes

The main cause of the quakes is the sudden release of stress from the faults in the Earth’s crust. In this guide on how to do a cause and effect essay , we will cover the causes of an earthquake. As the continuous motion of layers transpires, it causes a gradual build-up of pressure on both sides of a fault. This happens because of plate boundaries that are moving. Once the stress is too significant, it is released in a shaky movement. So, how are earthquakes caused? Here are the factors causing quakes.

Tectonic Movements of the Earth

One of the leading causes of an earthquake is movement from the tectonics. This is a shift of the planes making up the crust. Our planet consists of about a dozen major plates and several minor ones and is constantly changing.

The tectonic plates frequently move slowly, but sometimes, they get stuck because of friction. When the stress on the crust becomes more significant than the friction, an earthquake happens to release energy. This brings about a shaky feeling in steps through the planet’s crust. Little movement from the tectonic caused big things such as the happenings in the Ring of Fire.

Seismicity Ripples

Seismic waves are one of the causes of earthquakes. These are elastic ripples generated by an impulse, like an earthquake. The energy from the fault in the crust of the planet will radiate outward in different directions through seismicity. Think of it as ripples on a pond. As the ripples move through the surface, they shake the floor and anything on it. These can be in the form of ripples, which is when an earthquake happens more than once. North Carolina earthquake events occur because of seismicity, although they don’t have significant damage.

Compressions in the Crust of the Earth

Compression in the crust happens when plate tectonics are pushed together. The crust will become shorter and thicker, and depending on how it reacts to the force, it can lead to an earthquake. Due to compression, many quakes that occur in Australia are caused by these shifts along faults. Also, the main cause of the Northridge earthquake 1994 was the compressions on the planet’s surface.

Volcanic Eruptions

Volcanic eruptions are one of the less likely causes of an earthquake, depending on the volcano that erupts. The earthquake will be triggered when an explosion of an explosive volcano. These ripples have a wider effect than volcanic eruptions when they trigger an earthquake. In the case of volcanic eruptions, around 20 miles of the region around the volcano will be affected when it erupts. The largest volcanic tremor took place under Mount St. Helens in 1981 , with an intensity of 5.5.

Disturbances on the Surface

In general, an earthquake can be caused by disturbances on the surface. Technology advancement is one of the popular cause/effect essay topics , which is to some extent responsible for catastrophes like an earthquake. Humanity builds skyscrapers, constructs dams, and gets water from underground. Dams and reservoirs are known to trigger earthquakes, especially when a dam structure fails.

For instance, the 2008 happening in Sichuan , China, which killed about 70,000 persons, was triggered by the nearby Zipping Dam construction. Another disturbance is groundwater extraction, as this can destabilize an existing fault. Hydraulic fracking is a method of extracting natural resources. It works when shale formations underneath are injected with a mixture of chemicals and water at high pressure. Fracking has had such an impact on the environment causing earthquakes.

Big buildings and skyscrapers can also add significant pressure on the Earth’s surface and crack rudimentary rocks.

Effects of Earthquakes

When an earthquake happens, it leaves behind five primary outcomes and fires, a significant secondary impact of quakes. The effects of earthquakes on the Earth are often devastating, with people getting killed and injured, buildings getting destroyed, and the emotional and mental health of those affected. That’s why the investigation of this topic is so crucial in minimizing the adverse outcomes.

If you need an essay discussing this or any similar topic, our custom essay writing services can help you get the job done quickly and professionally. Now, let’s get to the main repercussions of quakes.

Ground Shaking

One of the most negative effects of earthquakes is surface shaking. During this time, buildings can be damaged, humans and animals will not be able to stand up or move around, and objects can be tossed around regardless of how big they are. Lives are taken in earthquakes but not directly by the shaking. Instead, it is caused by shaking, like buildings collapsing or getting hit by large objects.

The shaking of unstable slopes and direct blowout during an earthquake can lead to a landslide. Landslides are harmful effects of earthquakes and can damage buildings, tumbling hilltop homes, and block roads and transport lines. When a landslide happens, parts of the planet slide down and block an area. It can affect transportation after the earthquake, causing increased expenditure and leading to injuries and death for people there.

Surface Rupture

Another effect of quakes is surface breaking, which happens when the earthquake breaks the surface. As the earthquake occurs along a fault-line, it breaks through the Earth’s surface and can damage roads, pipelines, railway lines, tunnels, and airport runways. They will be damaged in the aftermath of an earthquake. An example of surface damage during an earthquake was the 1906 quake in California. The main cause of the quake was a slip of the San Andreas fault. The San Andreas fault is a major fracture of the planet’s crust.

Although this is a less common effect, an earthquake causes a tsunami. Tsunamis are water or tidal shakes that cause grave danger to places around the world, especially those in the Pacific Northwest region. An earthquake can cause the seafloor to move vertically apart from the normal floor. This will shake up the ocean and come in a series of floods to the beach. Tsunamis can move more than 700 kilometers per hour, causing flooding. It can damage properties and lead to death and injury too. Places close to the ocean are often subjected to tsunamis during an earthquake.

Liquefaction

Liquefaction is one of the outcomes of an earthquake that happens on the unconsolidated surface. When sediment grains are made to float in groundwater, the soil will lose all its solidity, and this is liquefaction. Tremors and earthquakes can cause mud and sand to spray over a couple of meters, posing a danger to buildings, train lines, gas lines, roads, and airport runways. Buildings can tip over and sink because of the liquefied soils, as occurred in the 1964 Niigata earthquake in Japan. Even septic tanks and gas tanks can float to the surface. Liquefaction after earthquakes leads to damages worth millions of dollars.

Earthquakes can have devastating consequences, so learning more about their causes and effects can be extremely beneficial. Recently, scientists have made tremendous progress in understanding the mechanisms behind earthquakes. To develop a deeper understanding of earthquakes, students may be required to write a coursework for me exploring the causes and effects of them. For example, they can focus on exploring tectonic plates and how they move and affect the ground, as well as the effect of natural conditions like weather and climate on their development. Additionally, the effects of an earthquake, such as structural damage and the resulting landslides, tsunamis and fires, can be further investigated in other science studies.

This essay has highlighted the cause and effect of earthquakes.  Earthquakes are severe natural disasters caused by shifts in the crust of the Earth. Compressions on the planet’s surface, human disturbances like skyscrapers and dams, and tectonics moving can cause earthquakes.  When they occur, consequences like landslides, ruptures, tsunamis, and more will follow. Some of the top countries prone to quakes are China, Indonesia, Turkey, Peru, Iran, Turkey, the United States, Japan, and Italy. China has gone through 157 earthquakes between 1900 and 2016. People living in these areas have precautions taken to protect themselves from injury during an earthquake.

Over the centuries, earthquakes have been responsible for millions of deaths and an incalculable amount of damage to property. Depending on their intensity, earthquakes (specifically, the degree to which they cause the ground’s surface to shake) can topple buildings and bridges , rupture gas pipelines and other infrastructure, and trigger landslides , tsunamis , and volcanoes .  These phenomena are primarily responsible for deaths and injuries. Very great earthquakes occur on average about once per year.

Earthquake waves, more commonly known as seismic waves , are vibrations generated by an earthquake and propagated within Earth or along its surface. There are four principal types of elastic waves: two, primary and secondary waves, travel within Earth, whereas the other two, Rayleigh and Love waves, called surface waves, travel along its surface. In addition, seismic waves can be produced artificially by explosions.

Magnitude is a measure of the amplitude (height) of the seismic waves an earthquake’s source produces as recorded by seismographs . Seismologist Charles F. Richter created an earthquake magnitude scale using the logarithm of the largest seismic wave’s amplitude to base 10. Richter’s scale was originally for measuring the magnitude of earthquakes from magnitudes 3 to 7, limiting its usefulness. Today the moment magnitude scale, a closer measure of an earthquake’s total energy release, is preferred.

Earthquakes can occur anywhere, but they occur mainly along fault lines (planar or curved fractures in the rocks of Earth’s crust ), where compressional or tensional forces move rocks on opposite sides of a fracture. Faults extend from a few centimetres to many hundreds of kilometres. In addition, most of the world’s earthquakes occur within the Ring of Fire , a long horseshoe-shaped belt of earthquake epicentres , volcanoes , and tectonic plate boundaries fringing the Pacific basin .

earthquake , any sudden shaking of the ground caused by the passage of seismic waves through Earth ’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.” Earthquakes occur most often along geologic faults , narrow zones where rock masses move in relation to one another. The major fault lines of the world are located at the fringes of the huge tectonic plates that make up Earth’s crust. ( See the table of major earthquakes.)

Little was understood about earthquakes until the emergence of seismology at the beginning of the 20th century. Seismology , which involves the scientific study of all aspects of earthquakes, has yielded answers to such long-standing questions as why and how earthquakes occur.

About 50,000 earthquakes large enough to be noticed without the aid of instruments occur annually over the entire Earth. Of these, approximately 100 are of sufficient size to produce substantial damage if their centres are near areas of habitation. Very great earthquakes occur on average about once per year. Over the centuries they have been responsible for millions of deaths and an incalculable amount of damage to property.

The nature of earthquakes

Causes of earthquakes.

Earth’s major earthquakes occur mainly in belts coinciding with the margins of tectonic plates. This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps, which show instrumentally determined epicentres. The most important earthquake belt is the Circum-Pacific Belt , which affects many populated coastal regions around the Pacific Ocean —for example, those of New Zealand , New Guinea , Japan , the Aleutian Islands , Alaska , and the western coasts of North and South America . It is estimated that 80 percent of the energy presently released in earthquakes comes from those whose epicentres are in this belt. The seismic activity is by no means uniform throughout the belt, and there are a number of branches at various points. Because at many places the Circum-Pacific Belt is associated with volcanic activity , it has been popularly dubbed the “Pacific Ring of Fire .”

A second belt, known as the Alpide Belt , passes through the Mediterranean region eastward through Asia and joins the Circum-Pacific Belt in the East Indies . The energy released in earthquakes from this belt is about 15 percent of the world total. There also are striking connected belts of seismic activity, mainly along oceanic ridges —including those in the Arctic Ocean , the Atlantic Ocean , and the western Indian Ocean —and along the rift valleys of East Africa . This global seismicity distribution is best understood in terms of its plate tectonic setting .

Natural forces

Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth . The energy can be released by elastic strain , gravity, chemical reactions, or even the motion of massive bodies. Of all these the release of elastic strain is the most important cause, because this form of energy is the only kind that can be stored in sufficient quantity in the Earth to produce major disturbances. Earthquakes associated with this type of energy release are called tectonic earthquakes.

The Lowdown on Earthquakes: A Tectonic Tango

Have you ever wondered why the Earth takes a little shimmy now and then? It all boils down to a fiery temper tantrum deep below the surface. The Earth’s crust is fractured into giant slabs called tectonic plates, constantly jostling for position like tectonic bumper cars. When these plates grind against each other, snag, or slam into one another, the sudden release of energy sends shockwaves rippling through the Earth-that’s your basic earthquake recipe.

Think of it like a giant trampoline. When you jump on one side, the other side bounces up, right? Earthquakes are kind of like that, except instead of a bouncy mat, you’ve got a whole planet in play. The epicenter, the spot where the plates first break free, is like the spot where you land on the trampoline. From there, the waves radiate outwards, causing the ground to shake with varying intensities depending on the strength of the earthquake and your distance from the epicenter.

Causes of Earthquakes

• Tectonic Plate Movements : Large pieces called tectonic plates divide the Earth’s surface. When these plates move against each other, they can get stuck and build up pressure. Eventually, this pressure is released, causing the ground to shake, which we feel is an earthquake.
• Faults and Fault Lines : Imagine the Earth’s crust as a giant puzzle of pieces. Sometimes, these pieces don’t fit perfectly together, and they can move past each other along lines called faults. An earthquake occurs when the rocks along a fault suddenly slip and move.
• Volcanic Activity : Sometimes, earthquakes can happen because of volcanic eruptions. When magma (hot molten rock) moves beneath the Earth’s surface, it can push against the surrounding rocks and cause them to break, leading to an earthquake.
• Human Activities : Human operations, such as mining or drilling for gas and oil, can cause earthquakes. When we dig deep into the Earth or inject fluids, we can change the pressure on the rocks and trigger earthquakes in areas that normally wouldn’t have them.
• Plate Boundaries : Most earthquakes happen along the edges of tectonic plates, where they meet. These places are called plate boundaries. Depending on how the plates are moving, earthquakes can occur at different plate boundaries, such as when plates collide, move apart, or slide past each other.

Types of Earthquake

Several types of earthquakes can be classified based on various factors, such as their underlying causes, the nature of their seismic waves, and their geographical distribution. Here are the primary types:

1. Tectonic Earthquakes : Tectonic Earthquakes are the most common and powerful type of earthquake. They occur when tectonic plates, the large rock slabs that make up Earth’s crust, move against each other. The movement can cause the plates to stick, then suddenly jerk free, releasing tremendous energy that travels through the Earth in waves. Tectonic earthquakes are further categorized based on the type of plate boundary involved, including:

• Strike-Slip Earthquakes : Occur at transform boundaries where plates slide past each other horizontally.
• Thrust (or Reverse) Earthquakes At convergent boundaries, one plate forces itself beneath another.
• Regular Fault Earthquakes : Occur at divergent boundaries where plates move away from each other, causing the crust to stretch and form faults.

2. Volcanic Earthquakes: These are smaller earthquakes that occur near volcanoes. They are caused by the movement of magma (molten rock) beneath the Earth’s surface. The movement of magma can crack the rock around the volcano, causing tremors. Volcanic earthquakes are usually much weaker than tectonic earthquakes.

• Collapse Earthquakes: Collapse Earthquakes are the weakest type of earthquake. They occur when the roofs of caves or mines collapse. Collapse earthquakes are usually very small and localized and rarely cause any damage.
• Explosion Earthquakes: These are earthquakes caused by human activity, such as bomb or mining explosions. They are similar to collapse earthquakes in that they are usually very small and localized.

Effects of Earthquake

The effects of an earthquake can be wide-ranging and impactful, affecting both the natural environment and human societies. Here are some of the key effects:

• Ground Shaking : Ground shaking is an earthquake’s most immediate and noticeable effect. This shaking can vary in intensity depending on the earthquake’s magnitude, the hypocenter’s depth (the point within the Earth where the earthquake originates), and the distance from the epicenter (the point on the Earth’s surface directly above the hypocenter). Severe shaking can cause buildings and structures to sway, crack, or collapse.
• Surface Rupture : In some cases, particularly in large earthquakes, the movement of tectonic plates can cause the Earth’s surface to rupture along fault lines. This can result in visible cracks or ground displacement , damaging roads, pipelines, and other infrastructure.
• Tsunamis : Earthquakes that occur underwater or near the ocean floor have the potential to generate tsunamis, which are large, destructive ocean waves. These waves can travel long distances across the ocean and cause widespread flooding and coastal erosion when they reach land.
• Landslides and Avalanches : The shaking and ground displacement caused by earthquakes can trigger landslides and avalanches, particularly in mountainous or hilly areas. These mass movements of rock, soil, and debris can bury homes, roads, and vegetation, posing additional hazards to human life and property.
• Liquefaction : In areas with loose, water-saturated soils, an earthquake’s intense shaking can cause the ground to behave like a liquid, a process known as liquefaction. This can result in the sinking or tilting of buildings, infrastructure, and other structures built on top of the affected soil.
• Infrastructure Damage : Earthquakes can cause extensive damage to buildings, bridges, roads, and other infrastructure, disrupting transportation networks, communication systems, and essential services such as water and power supply.
• Loss of Life and Injuries : The combined effects of ground shaking, structural collapse, and secondary hazards such as tsunamis and landslides can result in significant loss of life and injuries among affected populations.
• Psychological Impact : Earthquakes can have long-lasting psychological effects on individuals and communities, including anxiety, stress, and post-traumatic stress disorder (PTSD). The fear of aftershocks and the uncertainty surrounding recovery efforts can exacerbate these psychological impacts.
• Economic Consequences : Earthquakes can have profound economic consequences for affected regions, including property destruction, loss of life, and disruption of economic activities. These consequences include loss of income, decreased productivity, and increased financial strain on governments and relief agencies.

Mitigation and Preparedness

Mitigation and preparedness are crucial aspects of minimizing the impacts of earthquakes on human populations and infrastructure. Here are some key strategies and measures:

• Building Codes and Seismic Retrofitting : Strictly implementing and enforcing building codes while considering seismic hazards can ensure that structures are designed appropriately and constructed to withstand earthquake forces. Additionally, retrofitting older buildings and infrastructure to improve their earthquake resilience can help reduce the risk of collapse and casualties.
• Land Use Planning and Zoning : Proper land use planning and zoning can help mitigate the risk of earthquake-related hazards by restricting development in high-risk areas, such as floodplains, landslide-prone areas, and areas near fault lines. This can help minimize exposure to seismic hazards and reduce potential losses.
• Early Warning Systems : Developing and implementing early warning systems that detect seismic activity and provide warning before strong shaking arrives can help individuals and communities take protective actions, such as seeking shelter and shutting down critical infrastructure systems.
• Public Education and Awareness : Educating the public about earthquake risks, preparedness measures, and response procedures can help empower individuals and communities to take appropriate actions before, during, and after an earthquake. It includes conducting regular drills and exercises to practice emergency response plans.
• Infrastructure Resilience : Enhancing the resilience of critical infrastructure systems, such as transportation networks, utilities, and communication systems, can help minimize disruption and facilitate timely recovery efforts following an earthquake. It may involve reinforcing infrastructure components, diversifying supply chains, and incorporating redundancy into system designs.
• Community Preparedness and Resilience : Building community resilience through grassroots initiatives, community-based organizations, and partnerships between government agencies, non-profit organizations, and local stakeholders can help strengthen social cohesion, foster collective action, and enhance communities’ ability to withstand and recover from earthquakes.
• Emergency Response and Recovery Planning : Developing comprehensive recovery plans that outline various stakeholders’ roles, responsibilities, and procedures can help ensure a coordinated and effective response to earthquakes. These plans include pre-positioning emergency supplies, establishing evacuation routes, and coordinating search and rescue operations.
• International Cooperation and Collaboration : Promoting international cooperation and collaboration on earthquake research, monitoring, and preparedness can help improve the understanding of seismic hazards, enhance early warning capabilities, and facilitate the sharing of best practices and lessons learned across borders.

Staying Safe During an Earthquake

Staying safe during an earthquake requires quick thinking and decisive action. Here are some key steps to follow:

• Drop, Cover, and Hold On : When you feel the ground shaking, immediately drop to your hands and knees to prevent being knocked over. To shield yourself from falling objects, hide under a desk or other substantial piece of furniture. Hold on to the furniture with one hand and cover your head and neck with your other arm.
• Stay Indoors : If you’re inside a building, stay there during the earthquake. Move away from windows, glass doors, and exterior walls to avoid injury from broken glass or falling debris. Do not use elevators during an earthquake, as they may become stuck or malfunction.
• If You’re Outside : If you’re outdoors when an earthquake occurs, move to an open area away from buildings, trees, streetlights, and utility wires. Drop to the ground and cover your head and neck until the shaking stops.
• Stay Calm and Put: Stay calm during the earthquake and stay where you are until the shaking stops. Moving around during an earthquake can increase your risk of injury. Stay there and use a pillow to support your head and neck in bed.
• Be Prepared for Aftershocks : Smaller earthquakes, known as aftershocks, can happen hours or days after a bigger one. Take the same safety precautions as you did during the initial earthquake.
• Check for Gas Leaks and Fire Hazards : After the shaking stops, check for gas leaks, damaged electrical wires, and other fire hazards. If you smell gas or believe there might be a leak, immediately shut the gas supply at the main valve, then leave the area. Use a flashlight (not matches or candles) to inspect for damage, and Do not use electrical appliances until someone inspects them.
• Listen for Emergency Information : Listen to your local radio or television channels for updates and emergency information after the earthquake. Observe the guidance provided by emergency personnel and be ready to flee if needed.
• Assist Others : Check on family members, neighbors, and coworkers to ensure their safety and offer assistance. Be mindful of individuals with disabilities or special needs who may require additional assistance during an emergency.

After the Earthquake

Following the earthquake, you should do a few things to ensure you’re safe and okay, help others, and start healing. This is what you should do:

• Check for Injuries : Immediately after the shaking stops, check yourself and others for injuries. Provide first aid when necessary, and if there are any severe injuries, get medical help. Be mindful of broken glass, sharp objects, and unstable structures.
• Assess Damage : Survey your surroundings for damage to buildings, infrastructure, and utilities. In addition to looking for possible dangers like gas leaks, downed electrical lines, and falling debris, Verify that there are no structural issues, such as foundation, wall, or ceiling cracks.
• Evacuate if Necessary : If your home or building is severely damaged or emergency officials advise evacuation, leave the area immediately. Follow designated evacuation routes and assembly points, and bring essential items such as medications, important documents, and emergency supplies.
• Listen for Updates : Stay connected to local radio, television, or official social media channels for updates and instructions from emergency officials. Follow their guidance regarding evacuation orders, shelter locations, and safety precautions.
• Turn Off Utilities : If you suspect a gas leak or damage to electrical, water, or sewer lines, turn off the respective utilities at the main shut-off valves or switches. Avoid using open flames, electrical appliances, or running water until utilities have been inspected and deemed safe.
• Check on Neighbors and Loved Ones : Contact neighbors, family members, and friends to check their safety and offer assistance. Be prepared to provide aid, support, and comfort to those injured, displaced, or experiencing distress.
• Document Damage : Take photographs or videos of any damage to your property or belongings for insurance purposes. Keep records of repair costs and receipts, and communicate with insurance companies to help with the claims procedure.
• Secure Property : Secure or remove any hazardous items that could pose a risk of injury or further damage, such as broken glass, unstable furniture, or fallen objects. Cover broken windows and doors with plastic sheeting or boards to stop more exposure to the weather.
• Follow Recovery Procedures : Follow local guidelines and procedures for debris removal, building inspections, and recovery efforts. Cooperate with emergency responders, government agencies, and community organizations to facilitate recovery and rebuild affected areas.
• Take Care of Yourself : Practice self-care and prioritize your physical and emotional well-being after the earthquake. Get adequate rest, stay hydrated, and, if necessary, ask for help from family members or mental health specialists.
