List of earthquakes in Ecuador
This list of earthquakes in Ecuador is a list of notable earthquakes that have affected Ecuador in recorded history.
Tectonic setting
The active
Seismicity
Earthquakes that affect Ecuador can be divided into those that result from movement on the subduction interface along the plate boundary, those that result from deformation within the South American and Nazca Plates and those that are associated with active volcanoes.
Interplate earthquakes
Megathrust events along the subduction interface generate the largest earthquakes, often triggering destructive tsunamis, such as the 1906 Ecuador–Colombia earthquake.
Intraplate earthquakes
The most damaging earthquakes to affect Ecuador are those associated with faulting within the South American Plate, such as the 1949 Ambato earthquake.
Earthquakes within the downgoing Nazca Plate, such as the Mw 7.1 event of August 2010, are generally too deep to cause significant damage in Ecuador although they are felt over a wide area.[3]
Volcanic earthquakes
Swarms of relatively small earthquakes are commonly associated with volcanic activity, such as the Quito swarm in 1998-1999 related to the
