The agency is reporting a depth of 18.4 km (11.4 miles). In September 1985, a magnitude 8.1 earthquake killed more than 9,500 people in Mexico City. More than 360 people died in the cities of Morelos, Mexico City, Guerrero, Oaxaca, and Puebla. Overall, the consequences of slope instabilities caused by the 2017 Puebla-Mexico City earthquake were relatively minor compared with the reported structural damage. CAEE Reconnaissance Report on September 19, 2017 Puebla-Morelos Earthquake in Mexico Cocos plate subducts, it melts. The size of the area affected by earthquake-induced landslides and the threshold MMI for landslide observations from this event was consistent with observations from previous earthquakes [ 1 , 12 , 13 ]. According to 2017 Earthquake Impact Database (source), the death toll now stands at 248 (Mexico City 117, Puebla 43, Morelos 72, Oaxaca 1, Guerrero 3). This process probably caused the magnitude 8.1 earthquake. Past events with this alert level have required a national or international level response. The location, depth, and normal-faulting mechanism of this earthquake indicate that it is likely an intraplate event, within the subducting Cocos slab, rather than on the shallower megathrust plate boundary interface. Mexico City started to receive earthquake alerts from the earthquake early warning system in 1991 [Espinosa-Aranda et al., 1995; Goltz and Flores, 1997]. EMSC is reporting M7.1 at a depth of 30 km (18.6 miles). As the oceanic crust is pulled downward, it melts; the molten material is then forced upward through weaknesses in the overlying continental crust. The Sept. 19 earthquake’s epicenter was some 75 miles southeast from the Mexican capital, near Puebla. , From Simple English Wikipedia, the free encyclopedia, Location of epicenter in Mexico and Puebla, "Réplicas hasta las 12:30 hrs del 23/09/2017", "Central Mexico earthquake kills scores, topples buildings", "Powerful Earthquake Shakes Mexico On 32nd Anniversary Of Deadly Temblor", https://simple.wikipedia.org/w/index.php?title=2017_Puebla_earthquake&oldid=6922680, Creative Commons Attribution/Share-Alike License. 2017-09-19 18:14:38 UTC 7.1 magnitude, 51 km depth Ayutla, Puebla, Mexico 7.1 magnitude earthquake 2017-09-19 18:14:38 UTC at 18:14 September 19, 2017 UTC The earthquake occurred at a depth of 57 km and the epicenter was located approximately 60 km southwest of Puebla, Mexico and 120 km southeast of Mexico City, Mexico.

A major earthquake registered by the USGS as M7.1 hit Puebla, Mexico at 18:14 UTC (13:14 local time) on September 19, 2017. Because oceanic crust is relatively dense, when the Pacific Ocean floor encounters the lighter continental crust of the Mexican landmass, the ocean floor is subducted beneath the North American plate creating the deep Middle American trench along Mexico's southern coast. Recent earthquakes in this area have caused secondary hazards such as tsunamis and landslides that might have contributed to losses.

Tuesday's earthquake, however, was caused by crumpling arising from the downward bending of the sinking Cocos Plate, rather than directly by slippage between plates. In June 1999, a M7.0 at 70 km (43 miles) depth, just to the southeast of the September 19, 2017 earthquake, caused 14 fatalities, around 200 injuries, and considerable damage in the city of Puebla (MMI VIII).
