A moment magnitude M w 7.0 or 7.1 earthquake occurred near the city of Acapulco in the Mexican state of Guerrero at 20:47 local time on 7 September with an estimated intensity of VIII (Severe) on the MMI scale. [1] [2] The earthquake killed 13 people and injured at least 23 others. At least 1.6 million people in Mexico were affected by the ...
There have been five recorded earthquakes over 7.0 in magnitude that have occurred in the NPDB, including this event. Other earthquakes that have occurred in this region include the 1882 earthquake near Costa Rica, the 1904 Costa RIca earthquake with a magnitude of 7.2, the 1914 Panama earthquake and the 1991 Limon earthquake in Costa Rica ...
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 1960 Valdivia earthquake and tsunami (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) occurred on 22 May 1960.Most studies have placed it at 9.4–9.6 on the moment magnitude scale, [1] while some studies have placed the magnitude lower than 9.4, [6] [7] making it the most powerful earthquake ever recorded.
Shockwaves from the earthquake hit the mouth of the Río Balsas on the coast at 7:17 am and hit Mexico City, 350 km (220 mi) away, two minutes later at 7:19 am. [12] The 19 September quake was a multiple event with two epicenters and the second movement occurring 26 seconds after the first.
Southwestern Peru has a history of very large earthquakes. The June 23 shock originated just southeast of the source of a magnitude 7.7 earthquake that occurred in 1996, and it appears to have involved rupture of part of the plate boundary segment that produced an earthquake of magnitude approximately 9.0 in 1868.
A major earthquake struck northern Peru on November 28, 2021, 5:52 a.m. local time with a magnitude of 7.5 on the moment magnitude scale between the Amazonas and Loreto departments of Peru. [3] A maximum Modified Mercalli intensity (MMI) of VII (Very Strong) was reported in the town of Santa Maria de Nieva according to the Geological Institute ...
On 9 October 1995, a magnitude 7.6 earthquake struck about 50 km to the northwest killing at least 49 people and leaving 1,000 homeless. The most deadly earthquake in the region occurred about 170 km to the south-east on 19 September 1985.
