The extent to which tectonic processes represent a hazard depends upon when and where they are experienced

There are many earth hazards everywhere on earth which both humans and nature share a role, natural hazards such as volcanoes, floods, forest fires, and avalanches, and purely of human origin like the chemical leak, oil spills, and human made earthquake. But one of nature's most dangerous hazard that we have to live with in California must are earthquakes. A earthquake is when two tectonic plates slowly slip past each other and get stuck which creates friction. The point where the two blocks slip is called the fault or fault plane. When the earthquakes start is at the hypocenter, and the point above the hypocenter is called the epicenter. After a earthquake, there are aftershocks that are smaller earthquakes, some aftershocks can be as large

Earthquakes are one of the most destructive natural disasters. They destroy buildings, collapse roads and bridges, change landforms, and have cause millions of deaths throughout the years.

Did you know that earthquakes can build mountains and volcanoes,destroy houses, lose of jobs, and it have even killed people.An earthquake is when two contients hit together really hard to form a volcanoes or mountains. Gondwana was from 250 years ago. In the blog, there was blue smoke everywhere and helicopters clatter the sky. In the news report, the Loma Prieta Earthquake, killed people and take lots of people out of their houses.In the insurance claim, it would cost over milloins of dollars to fix your home.Earthqukes have an effect on people, earth, and properties.

Geological and environmental circumstances that have an affect have been designated geohazards. There are many different categories of geohazards that can occur in the world. Some of these geohazards include landslides, earthquakes, tsunamis, volcanoes, lahars, and hydrothermal eruptions. These natural disasters can all have both short and long term effect on the surrounding environment. It is important to recognize the different kinds of geohazards and how to know if we can take preventive measures or very minimally understand which areas may be more susceptible to a geohazard event.

Did you know that earth's plates are not fixed together? They slide over each other, that causes earthquakes. Earthquakes can damage miles and miles of damage,death,and homeless people. Earthquakes can move continents farther from others,but this process can take years to accomplish. Scientists know this because in some way the continents look like they could fit all together, when it was it was called Pangea.

First off, earthquakes affect humans in many ways. One way that earthquakes affect humans is by killing and injuring them. According to the news report “Loma Prieta Earthquake” it states that “earthquake killed more than 60 people, and injured almost 4,000.” Earthquake Loma Prieta caused much damage to San Francisco. Another way earthquakes affect humans is by damaging roads which could put people at risk of being injured. According to the blog “A Rough Commute” the author states “A section of asphalt six lanes wide has been tilted up like a castle drawbridge.” Also earthquakes can affect humans when they are driving by when the debris of the earthquake rises in the air it can cause it to be hard to see. According to “A Rough Commute” it states that “A huge cloud of blue smoke is rising in the east.” This smoke was caused by debris from an earthquake.

Coppola's (2011) study explained Quebec has experienced different types of disaster such as flight crash, city fire, derailment, bridge collapse, gas explosion and etc historically. Technological disasters bring about negative

A natural hazard is an extreme event that occurs naturally and causes harm to humans or other things we care about, while a Geomorphic hazard is that originating from the lithosphere including, volcanic eruption, earthquake and tsunamis. An earthquake is a sudden violent shaking of the ground, typically showing great destruction. This report will focus on the Great Chilean earthquake. I will report and examine the causes, details, effects including, social, environmental and economical. I will also examine what has been done to prepare, prevent and minimise the hazard and suggest ways to further minimise the effects of this hazard.

The geographic phenomenon causes a mysterious shaking and even will cause structures to collapse. The shaking from them is very destructive and a threat to human life if strong enough. Occurring every day, but some are not powerful enough to be felt because they contrast from being harmless to deadly. They are natural disasters that happen unexpectedly while destroying almost everything in just under a few minutes and extremely harmful and more powerful than a nuclear object would be. Earthquakes are incidents when the rocks under the earth move, freeing energy that later causes shaking. The plates move in many different ways and occur just as frequently as in the past (Wells). An earthquake is the most deadly disaster with many leading factors and disputes (Stock).

In addition to the plate tectonic setting, the geological composition of the region also was to blame for the vast destruction of the earthquake. The land the city is built on is primarily sand and clay. This is a very soft, fertile soil composition. While these characteristics are very beneficial for farming, they can be detrimental to the region during an earthquake. This soil is loosely compacted, which allows seismic waves to reverberate vibrations, worsening the impact. This causes the tall, multistoried buildings found in the city to sway back and forth, as the ground holding them is so unstable. Also, soil of this makeup causes

Earthquakes form at plate boundaries, where lithospheric plates are converging, diverging, or sliding past each other (Erickson 39). The longer and deeper the fault goes, the larger and more dangerous the earthquake will be (Erickson 49). Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth (“Earthquakes”). Half of the world’s population lives in coastal regions, where they are extremely vulnerable to earthquake damage (Erickson 28). Earthquakes are sometimes caused by human activities, like the injection of fluids into deep wells, the discharge of large underground nuclear explosions, mines, and filling large reservoirs (“Earthquake”).

1. Buildings are designed to support the walls, roof and all the stuff inside to keep them standing. Earthquakes present a lateral/sideways, load to the building structure that is a bit more complicated to prepare for. One way to make a simple structure more resistant to a quake is to tie the walls, floor, roof, and foundations into a rigid box that holds together when shaken by a quake (Imagination Station 2017)

When the tectonic plates slip and the energy is released at the earth’s surface, endless effects occur as a result. While this is taking place, two types of waves associated with this action result: body waves and surface waves. Both of these categories are divided into sub categories, but they essentially serve the same purpose. Body waves are the first set of waves to hit the earth’s surface, and they resemble water waves by the way they move. They slowly move the material, horizontally displacing the soil. Surface waves may move the material horizontally, but they also have the potential to move the ground vertically. Both of these effects present an opportunity for disaster to

The word geo-hazards come from two words ‘geo ' formed from the word ‘geological’ which means from the earth and ‘hazard ' which is a situation that is bound to pose a risk to property, the environment or life. It is, therefore, a geological condition capable of causing damage. Geo-hazards are geological or environmental situations that comprise of both long and short term geographical progressions. These hazards can be fairly small featured, butcan also be magnified in enormous dimensions that are likely to affect the local and regional socio-economy to a large extent. Some simple human activities such as drilling through zones that are over-pressured could result in significant risks, and as a result,

Even population density (the number of people living per square km) places a significant factor affecting the damage because if the density of people is high in a place then more deaths and destruction of buildings. Example Russia and Nepal, the effect of earthquake in Nepal would be more compared to Russia because the population density of Nepal is 196.85 and 8.4 in Russia. The time of the day also a factor for the damage, night time earthquakes will have less number of deaths, morning people would scatter all around the city which would lead to more deaths. When the strength of the earthquakes in very high then there are chances of secondary hazards like landslides, storms, avalanche to take place which would create more damages and destruction.
