The earth's crust is divided into several major plates, some 50 miles thick, which move slowly and continuously over the earth's interior.
Most earthquakes occur as the result of slowly accumulating pressure that causes the ground to slip abruptly along a geological fault plane on or near a plate boundary. The resulting waves of vibration within the earth create ground motion at the surface that vibrates in a very complex manner.
The point where the fault first slips is the "focus" or "hypocenter" of the earthquake. A theoretical point on the earth's surface directly above the focus is the "epicenter" of the earthquake. The epicenter of the January 17, 1994 Los Angeles earthquake was located in the city of Northridge in the San Fernando Valley.
Yes, there are caldera and composite volcano.
The most recent earthquake in China occurred in Yunnan Province on May 21, 2021. The earthquake had a magnitude of 6.4 and caused significant damage in the region.
The strongest earthquake ever recorded occurred in Chile on May 22, 1960. This earthquake had a magnitude of 9.5 on the Richter scale.
While it is theoretically possible for a 10.0 earthquake to occur in the future, the likelihood of such a powerful earthquake happening in the near future is extremely low. Earthquakes of that magnitude are very rare and typically occur over longer time periods.
waves occur all the time but after an earthquake tidal waves occur. Tidal waves are the cause of the tectonic plates colliding underwater. After the collision over time the wave goes form a small bump in the water to growing bigger and bigger into giant super wave capable of destroying towns.
Yes. An earthquake may occur in the ocean.
dumb question
Aftershocks can occur hours or days after an earthquake.
No, they can't tell that it is a foreshock until a larger earthquake happens. (The largest main earthquake is called the mainshock)
Yes, there are caldera and composite volcano.
A tsunami is an ocean wave that is caused by an earthquake. It would occur after an earthquake.
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
Small foreshocks that precede a major earthquake can occur
on 11th march 2011 at 9.am earthquake occur exactly in japan
Although earthquake may occur anywhere on the earth, Japan is the country where frequency of earthquake is maximum. This happens due to the movement of tectonic plates of the earth in different directions.
An earthquake CAN NOT destroy a country.
There is no requirement for nausea to occur due to an earthquake or any other natural phenomenon.
