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.
An foreshocks and aftershocks
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.
Minor earthquakes that precede larger earthquakes are typically referred to as foreshocks. These smaller tremors can occur before a main earthquake event and provide a warning sign of potential larger seismic activity.
Yes, earthquakes can have foreshocks, which are smaller earthquakes that occur before the main event. These foreshocks can help seismologists to predict the likelihood and intensity of an upcoming larger earthquake.
An aftershock is an earthquake that comes after another, larger earthquake often within a few days.
earthquakes that immediately follow a major earthquake are called "aftershocks" as to small earthquakes before large earthquakes are called "foreshocks".
Compare and contrast it with what?
1. Compare 2. Contrast
compare is when you compare two things that are the same and contrast is when you compare two things that are different.
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
It is not possible to issue warnings about earthquakes at present as they cannot be predicted with current knowledge.It is hoped that in the future, warnings will be able to be issued for some types of earthquakes that have foreshocks (smaller earthquakes that happen before the major quake). There is no mention of foreshocks for the Gisborne 2007 quake on the Geonet website. There were aftershocks. See the related links.
