Have you experienced Earthquake?

yes. a lot already.

I have not and hope I never do. I am scared of them.

Some earthquakes have anthropogenic sources, such as extraction of minerals and fossil fuel from the Earth's crust, the removal or injection of fluids into the crust, reservoir-induced seismicity, massive explosions, and collapse of large buildings. Seismic events caused by human activity are referred to by the term induced seismicity. They however are not strictly earthquakes and usually show a different seismogram than earthquakes that occur naturally. A rare few earthquakes have been associated with the build-up of large masses of water behind dams, such as the Kariba Dam in Zambia, Africa, and with the injection or extraction of fluids into the Earth's crust (e.g. at certain geothermal power plants and at the Rocky Mountain Arsenal). Such earthquakes occur because the strength of the Earth's crust can be modified by fluid pressure. Earthquakes have also been known to be caused by the removal of natural gas from subsurface deposits, for instance in the northern Netherlands. The world’s largest reservoir-induced earthquake occurred on December 10, 1967 in the Koyna region of western Maharashtra in India. It had a magnitude of 6.3 on the Richter scale. However, the U.S. geological survey reported the magnitude of 6.8. [3] The detonation of powerful explosives, such as nuclear explosions, can cause low-magnitude ground shaking. Thus, the 50-megaton nuclear bomb code-named Ivan detonated by the Soviet Union in 1961 created a seismic event comparable to a magnitude 7 earthquake, producing the seismic shock so powerful that it was measurable even on its third passage around the Earth. In an effort to promote nuclear non-proliferation, the International Atomic Energy Agency uses the tools of seismology to detect illicit activities such as nuclear weapons tests. The nuclear nations routinely monitor each other's activities through networks of interconnected seismometers, which allow to precisely locate the source of an explosion. Sports games have been known to inadvertently produce microearthquakes. This phenomenon was first seen in 1988 with the Earthquake Game at Louisiana State University, in which fans stamped their feet and jumped up and down vigorously enough to have the effect register on the campus seismograph. Earthquakes happen every day around the world, but most of them go unnoticed and cause no damage. Large earthquakes however can cause serious destruction. They may be caused by the ground shaking, a tidal wave or tsunami, fire or by gas or petrol leaks. Most large earthquakes are accompanied by other, smaller ones that can occur either before or after the 'main shock'. The power of an earthquake covers a large area, but in a very large earthquake, it can even cover the whole planet. Scientists can locate the point from which the earthquake started. That point is called its 'focus' or 'hypocenter'. The location on the surface of the earth directly above the hypocenter is known as the 'epicenter' yess i have face tis one. and i am alive...

no

no i have not but i would be interested in reading anyones experiences of them. i have just gone to university to read earth sciencess so anything i can learn would be helpful

s last year

ya i have but it was a real mild 1,did nothing,thank god

till now i never experienced it.

I grew up in California. I have experienced lots of earthquakes. They dont scare me like I have seen some people react to them. But other natural disaters like tornados and flooding scare me a lot.

not yet

yes

no...

Yes, I have experienced several times but one of them it was very terrible. I remembered that movement till now.

i have... and trust me.. its terrifyin

I live where there are earthquakes all the time. I have grown up with them so the are not that big of a deal to me. Good foot massage! I live very close to a fault line! It is called the San Andres Fault.

yes I have, it was a very small earthquake, but trust me, it's really frightening!

U afraid of quakes,That's why u are moving in Rocket.

I experienced an earthquake in May. I didn't know it's an earthquake at the time. The earthquake was not so BIG, I only feel a little shake, and just thought it's only my wrong feeling. :)

I have never experienced an earthquake before. I don't know if I ever want to either.

yes... sure was really thrilling....
