What should you do in case of an earthquake?

If you are INDOORS — STAY THERE! Get under a desk or table and hang on to it (Drop, Cover, and Hold on!) or move into a hallway or against an inside wall. STAY CLEAR of windows, fireplaces, and heavy furniture or appliances.

How do you stay safe during an earthquake essay?

If you are indoors when a earthquake hits:Drop down and take cover under a desk or table. Stay inside until the shaking stops and it is safe to exit.Stay away from bookcases and other furniture that can fall on you.Stay away from windows and light fixtures.If you are in bed hold on and stay there.

What are the effects of earthquakes essay?

First of all, the shaking of the ground is the most notable effect of the Earthquake. Furthermore, ground rupture also occurs along with shaking. This results in severe damage to infrastructure facilities. The severity of the Earthquake depends upon the magnitude and distance from the epicenter.

What are the 3 causes of earthquakes?

Causes of Earthquakes in GeneralInduced Earthquakes. Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.Volcanic Earthquakes. Volcanic quakes are associated with active volcanism. Collapse Earthquakes.

What are the 10 causes of earthquake?

Things that cause earthquakesGroundwater extraction – decrease in pore pressure.Groundwater – increase in pore pressure.Heavy rain.Pore fluid flow.High CO2 pressure.Building dams.Earthquakes.No earthquakes (Seismic quiescence)

How does an earthquake start?

An earthquake is caused by a sudden slip on a fault. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth’s crust and cause the shaking that we feel. In California there are two plates – the Pacific Plate and the North American Plate.

What is the most common cause of earthquakes?

Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don’t just slide smoothly; the rocks catch on each other.

How do humans cause earthquakes?

Mining, dam building, and fracking are among the causes. Just like earthquakes caused by nature, human-induced earthquakes have the potential to be dangerous, even deadly. And geologists are only just beginning to understand the repercussions these quakes could have on people and the environment.

Do normal faults cause earthquakes?

Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.

What is a normal fault earthquake?

normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

What type of fault is the most dangerous?

SAN FRANCISCO (KGO) — While the San Andreas fault gets much of the attention after the devastating 19 quakes, it’s the Hayward fault, which runs along the East Bay, that quake experts consider the most dangerous fault in America.

How do you identify a normal fault?

To correctly identify a fault, you must first figure out which block is the footwall and which is the hanging wall. Then you determine the relative motion between the hanging wall and footwall. Every fault tilted from the vertical has a hanging wall and footwall.

What is an example of a normal fault?

A normal fault is a fault in which the hanging wall moves down relative to the footwall. An example of a normal fault is the infamous San Andreas Fault in California. The opposite is a reverse fault, in which the hanging wall moves up instead of down. A normal fault is a result of the earth’s crust spreading apart.

What are the 4 types of fault?

There are different types of faults: reverse faults, strike-slip faults, oblique faults, and normal faults. In essence, faults are large cracks in the Earth’s surface where parts of the crust move in relation to one another.
