In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according ...

An aftershock is an earthquake that occurs after a previous earthquake, the mainshock. Rapid changes of stress between rocks, and the stress from the original earthquake are the main causes of these aftershocks, [34] along with the crust around the ruptured fault plane as it adjusts to the effects of the mainshock.

USGS scientists said informal observations can be a big help in understanding earthquakes, especially in a region where they’re less common. 4.0 aftershock hit New Jersey at 6 p.m. Friday
The 7.5-magnitude tremor that struck Turkey on Monday after the 7.8-magnitude earthquake was an unusually strong aftershock, according to seismologists.. Aftershocks are typically about 1.2 ...
The USGS recorded 28 aftershocks following Friday’s rare earthquake, with the largest aftershock – clocking in at a 3.8 magnitude – striking Gladstone, New Jersey, 20 minutes from the ...
Induced seismicity, typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on the Earth's crust. [10] Interplate earthquake, an earthquake that occurs at the boundary between tectonic plates. [11] Intraplate earthquake, an earthquake that occurs within the interior of a tectonic plate. [12 ...
Scientists have yet to pinpoint the fault that ruptured in New Jersey on April 5 and rattled much of the Northeast. Now, U.S. Geological Survey researchers are in the process of installing new ...
