What is an after 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.


What are earthquake after earthquake?

A small earthquake that happens after a larger one is called an aftershock. Aftershocks happen because the crust in the area where the main earthquake happened is adjusting to the earthquake's effects.


Can an aftershock of an earthquake be stronger than the earthquake itself?

Yes. However the preceding earthquakes (including the one that was originally the largest) are then downgraded or renamed as foreshocks and the new larger magnitude earthquake is termed the main shock.


What is an earthquake's aftershock called?

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.


Do after shocks of an earthquake happen within a week?

It depends! Depending upon the built-in energy at the epicenter before and after the earthquake (main shock), and/or the energy (especially stored at some weaker places) generated after the earthquake, aftershocks of an earthquake range in their time.For more details, refer: http://www.answers.com/library/Wikipedia-cid-1349 Aftershock

After shock?

A small earthquake that follows the main earthquake.


When is the after shock earthquake?

It's a smaller (or sometimes larger) earthquake after the main earthquake


What is the smaller shake called that follows the main earthquake?

The smaller shake that follows the main earthquake is called an aftershock. Aftershocks can occur minutes, hours, or even days after the initial earthquake and are caused by the adjustment of the Earth's crust to the stress changes generated by the main earthquake.


What are the main reasons of an earthquake?

Earth's crust shift into each other causing an earthquake


What are the main causes of tsunamis?

Tsunamis occur after an earthquake. Earthquakes that occur in the middle of the ocean can force a tsunami to make landfall.


Where are main spots of earthquakes?

The main spot, or epicenter is the center of the earthquake.

Compare and contrast aftershocks and foreshocks?

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.


How do aftershocks start?

Aftershocks occur as the crust adjusts to the stress changes caused by a main earthquake. They are smaller earthquakes that follow the main earthquake along the same fault line. The aftershocks may continue for days, weeks, or even months after the main earthquake.


What are the after shocks of an earthquake?

Aftershocks are smaller earthquakes that follow the main earthquake. They occur as the Earth's crust adjusts to the initial movement and release of stress. Aftershocks can be felt for days, weeks, or even months after the main earthquake.
