The 2009 Cinchona earthquake occurred at 1:21:35 pm local time on January 8 with an M wc magnitude of 6.1 and a maximum Mercalli intensity of IX ( Violent).The shock took place in northern Costa Rica, 30 kilometres (19 mi) north-northwest of San José and was felt throughout Costa Rica and in southern central Nicaragua.
Costa Rica lies above the convergent plate boundary where the Cocos plate is subducting beneath the Caribbean plate at a rate of 9 cm per year. Off the Nicoya Peninsula, the Cocos plate is subducting along the Middle America Trench, and the Nicoya Peninsula is unique in being one of the few landmasses along the Pacific Rim located directly above the seismogenic zone of a subduction megathrust ...
The 1910 Costa Rica earthquakes were a series of destructive seismic events that affected Cartago, Costa Rica from 13 April to 4 May. The sequence began with a M s 5.8 earthquake. The largest and most destructive in the sequence occurred on 4 May, measuring M s 6.4. A total of 2,450 people were killed and the city of Cartago was severely affected.
The Red Sismológica Nacional (National Seismological Network) reported the strength of the tremor as magnitude 4.6, at a depth of 80 kilometres, while the Observatorio Vulcanológico y Sismológico de Costa Rica (Volcanological and Seismological Observatory of Costa Rica) described it as a magnitude 4.8 earthquake at a depth of 100 km.

A landside on September 10 in Cerro del Chiquihuite, Mexico City killed five more people, caused one injury and left two missing. [366] [367] The suspected cause of the landslide was heavy rainfall and the quake which weakened soils on the hill. [368] A 14-year-old girl died from her injuries due to a collapsed wall on September 11. [369] [370 ...
The earthquake occurred as the result of shallow thrust faulting on or near the subduction interface between the Nazca and South American plates. At the location of this event, the Nazca plate moves east-northeast relative to South America at a velocity of about 74 mm/yr. [2] The Nazca plate, oceanic in origin, subducts eastward beneath the South American plate at a shallow angle from the Peru ...
