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 ...
Following the earthquake were more than 10 aftershocks greater or equal to magnitude 4.0. The strongest aftershock was a M w 5.3 occurring the day later. [3] The strongest aftershock had a maximum intensity of VIII (Severe), collapsing several already damaged but unoccupied homes. [21] [22] A total of 2,000 aftershocks were recorded. [17]

There is a greater than 99% probability of one or more magnitude 3.0 earthquakes in the area over the next day, a 74% chance of a magnitude 4.0 or larger, 22% chance of a magnitude 5.0 and larger ...
The 2021 South Sandwich Islands earthquakes were a pair of powerful earthquakes, followed by many strong aftershocks which struck along the South Sandwich Trench in August 2021. The quakes measured 7.5 and 8.1 on the moment magnitude scale, according to the United States Geological Survey. [4] [5] The mainshock is tied with another event in ...
Aftershocks ranging in magnitude 4's and 5's followed after the mainshock early morning in Philippines. A moderately strong shallow aftershock was felt at midnight on August 12. The strongest aftershocks were reported magnitude 5.1 and 5.7 intensities of III. [6] [7] The earthquake was felt mostly all over Mindanao and lasted for more than a ...
Magnitude-7 earthquakes in populated areas are uncommon but devastating: In August 2021, a magnitude-7.2 quake in Haiti killed more than 2,100 people. A magnitude-5.8 aftershock followed.
