The 2016 Ecuador earthquake occurred on April 16 at 18:58:37 ECT with a moment magnitude of 7.8 and a maximum Mercalli intensity of VIII (Severe).The very large thrust earthquake was centered approximately 27 km (17 mi) from the towns of Muisne and Pedernales in a sparsely populated part of the country, and 170 km (110 mi) from the capital Quito, [1] where it was felt strongly.

Three earthquakes in a 30 minutes period. Minor damages in households. Many people spent the night out in the street.

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.

Moderately damaging earthquakes strike between New York and Wilmington, Delaware, about twice a century, the USGS said, and smaller earthquakes are felt in the region roughly every two to three years.
The magnitude of an earthquake depends in part on the length of the geological fault on which the quake occurs. Longer faults result in stronger earthquakes. There are no known faults capable of ...
This can result in extremely deep earthquakes up to 700 kilometres (430 mi) in depth. [3] The base of this layer represents the downwards change in deformation mechanism from elastic and frictional processes (associated with brittle faulting) to a generally aseismic zone where ductile creep becomes the dominant process.
Mexico lies within two seismically active earthquake zones. The Baja California peninsula lies near the boundary of the Pacific plate and the North American plate, while southern Mexico lies just north of the boundary between the North American plate and the Cocos and Rivera tectonic plates. The Cocos plate is subducting under the North ...
“It is also possible that earthquakes can increase the stress at the continuation of the faults or nearby faults, which may trigger other earthquakes.” Does climate change affect seismic activity?
