1) fore shock
2) earthquake shock
3) after shock
I think you may be referring to aftershocks. Aftershocks are smaller tremors that can occur at any time for months after an earthquake as the pressure within Earth's crust is gradually released.
these are calle "aftershocks"
An earthquake's aftershock is a smaller earthquake that occurs in the same area after the main shock. Aftershocks can happen days, weeks, or even months after the main earthquake, and they are caused by the readjustment of the Earth's crust following the initial seismic event.
I'm assuming you know how earthquakes occur and all an aftershock is a smaller earthquake after a larger one. If the "aftershock" is larger than the main shock it is reclassified as the main shock and the previous "main shock" becomes a foreshock.
An earthquake is the movement of the tectonic plates, the little quake that happens after the main quake is called the aftershock.Aftershocks. If an aftershock is stronger than the original earthquake, it takes its place and trhe last earthquake becomes a pre-shock.
There would be a second earhquake after the first, it always do,just like the earthquake in the China in 2008. Actually, it is called an aftershock. If the aftershock was a higher valve then the first quake then the aftershock becomes the earthquake and the earthquake becomes the aftershock. Hope you get this. So to put it in perspective, the main hit is called an earthquake and any following disruptions are called aftershocks and not considered earthquakes. To answer the question: Geophysicists in the US have found that the "aftershocks" produced by earthquakes are triggered by the dynamic seismic waves from the main shock rather the changes in stress in nearby faults brought about by the rearrangement of the earths crust,as previously believed.
The earthquake that follows the major shock is the aftershock. Technically, there can be lots of them,happening hours, day, weeks, even months after the initial shock.
An aftershock is a smaller earthquake that follows the main earthquake, usually occurring in the same area and caused by the shifting of rock underground. Aftershocks can happen within hours, days, or even months after the initial earthquake. These can be as strong as or weaker than the main earthquake.
A foreshock is a smaller earthquake that occurs before a larger mainshock, providing a warning sign of the impending main event. An aftershock, on the other hand, is a smaller earthquake that occurs after a mainshock, as the Earth's crust adjusts to the stress changes caused by the initial seismic event.
Aftershocks are smaller earthquakes that occur after a larger event (the mainshock) in the same area. If an even larger earthquake occurs, then the original mainshock becomes a foreshock and the bigger event becomes the mainshock.
It could be "an aftershock"
