An earthquake is caused by 'plates' in the ground shifting and moving. and after a major shift there might be a small aftershock witch is when the 'plates' in the ground move slightly as they are going back into place
Small foreshocks that precede a major earthquake can occur
The shaking of the ground that precedes an earthquake is called a foreshock. Foreshocks can occur hours, days, or even weeks before the main earthquake event.
They are called aftershocks, or tremors.
That is the correct spelling of "earthquake" (damaging earth tremors).
After a strong earthquake, aftershocks may follow, causing further damage and hindering rescue efforts. Buildings and infrastructure may be severely damaged, leading to potential fires or water contamination. Displaced people may require emergency shelter and medical care.
Aftershocks
These are known as aftershocks.
Small tremors before a major earthquake are referred to as foreshocks. They occur before 70 percent of large seismic events, and to a lesser extent before smaller earthquakes.
They are known as aftershocks.
Small foreshocks that precede a major earthquake can occur
Earthquake tremors.
There are several things that may indicate an upcoming earthquake. Swarms, seismic activity, small tremors are the main indicators.
The shaking of the ground that precedes an earthquake is called a foreshock. Foreshocks can occur hours, days, or even weeks before the main earthquake event.
A seismograph records an earthquake while it is happening, but as of yet there are no machines that can predict earthquakes.
They are called aftershocks, or tremors.
