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 ...
What does magnitude mean in an earthquake? Magnitude is a measurement of the strength of an earthquake. ... Aftershocks are defined as smaller earthquakes that happen in days after a larger quake ...
Foreshock activity has been detected for about 40% of all moderate to large earthquakes, [2] and about 70% for events of M>7.0. [3] They occur from a matter of minutes to days or even longer before the main shock; for example, the 2002 Sumatra earthquake is regarded as a foreshock of the 2004 Indian Ocean earthquake with a delay of more than two years between the two events.

Aftershocks from devastating earthquakes in the 1800s near the Missouri-Kentucky border and in Charleston, South Carolina, may still be occurring, a study found.
The USGS recorded 28 aftershocks following Friday’s rare earthquake, with the largest aftershock ... a controller said in a radio transmission after the earthquake, meaning flights were being ...
Magnitude is a measurement of the strength of an earthquake. Officially it's called the moment magnitude scale. It's a logarithmic scale, meaning each number is 10 times as strong as the one ...
Remotely triggered earthquakes are a result of the effects of large earthquakes at considerable distance, outside of the immediate aftershock zone. [1] The farther one gets from the initiating earthquake in both space and time, the more difficult it is to establish an association. The physics of triggering an earthquake are complex.
