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.
What else can I help you with?
Is there any earthquake vocabulary words that start with the letter C?
Yes, there are caldera and composite volcano.
What part of china did the most recent earthquake occur?
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.
Where did the strongest earthquake occur in the world?
The strongest earthquake ever recorded occurred in Chile on May 22, 1960. This earthquake had a magnitude of 9.5 on the Richter scale.
What information do you need to completely describe where an earthquake started?
To completely describe where an earthquake started, you would need the coordinates of the earthquake's epicenter, the depth at which it originated within the Earth, and the fault line or tectonic plate boundary where the earthquake occurred. This information helps to pinpoint the exact location and provide insight into the geological context of the earthquake's origin.
Do waves occur before or after an earthquake?
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.
Can an earthquake occur in the ocean?
Yes. An earthquake may occur in the ocean.
Who do you know when earthquake may occur?
dumb question
What can occur hours or days after an earthquake?
Aftershocks can occur hours or days after an earthquake.
Is there any earthquake vocabulary words that start with the letter C?
Yes, there are caldera and composite volcano.
How can you tell an earthquake is gonna happen?
No, they can't tell that it is a foreshock until a larger earthquake happens. (The largest main earthquake is called the mainshock)
When would a tsunamic occur?
A tsunami is an ocean wave that is caused by an earthquake. It would occur after an earthquake.
A machine that tells you that an earthquake is coming is called?
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
What Major earthquakes are sometimes preceded by a smaller earthquake called what?
Major earthquakes are sometimes preceded by a smaller earthquake known as a foreshock. Foreshocks occur in the same region as the larger earthquake and can vary in magnitude. Not every major earthquake has foreshocks, but when they do occur, they may serve as a warning of the impending larger seismic event.
Small foreshocks that precede a major earthquake can occur .?
Small foreshocks that precede a major earthquake can occur
When did the earthquake occur exactly in Japan?
on 11th march 2011 at 9.am earthquake occur exactly in japan
When areas where earthquake occurs?
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.
Describe how an earthquake can destroy a country?
An earthquake CAN NOT destroy a country.
