Its when a minor earthquake is shaking next to a fault. and finally the big one happens
Small foreshocks that precede a major earthquake can occur
Foreshock is what you call one of the little earthquakes that come before the big earthquake or main shock. The main shock may be followed by a little earthquake that's called the aftershock.
Foreshocks can occur days, weeks, or even months before a major earthquake, though they often happen minutes to hours prior. Their unpredictability makes it challenging to use them as reliable indicators of an impending larger quake. Not all major earthquakes are preceded by foreshocks, and when they do occur, not all foreshocks will lead to a larger event.
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
A major earthquake that has happened in the past is often referred to as a seismic event or a historic earthquake. The specific location where the earthquake occurred is known as the earthquake's epicenter.
Small foreshocks that precede a major earthquake can occur
True! The small magnitude earthquakes that sometimes precede a major earthquake are known as fore shocks.
Foreshocks can occur hours, days, or even weeks before a larger earthquake, but there is no definitive timeline. Foreshocks are smaller earthquakes that precede a larger mainshock, and their occurrence can vary depending on the specific earthquake event.
An aftershock is a small earthquake that follows the main earthquake, while a foreshock is a small earthquake that often precedes, leads to, a major earthquake.

earthquakes that immediately follow a major earthquake are called "aftershocks" as to small earthquakes before large earthquakes are called "foreshocks".

Yes, major foreshocks preceded the earthquake on 11th March 2011 and major aftershocks succeeded the earthquake. There were hundreds of aftershocks of varying intensities, one even as great as 8 on the Richter scale causing a 10 meter tsunami.
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.
