On September 19th, 2022, a moment magnitude 7.6 earthquake struck the Pacific coast of Mexico in the state of Michoacán between the cities of Manzanillo and Zihuantanejo. This is the third major earthquake that has occurred in Mexico on September 19th in the last 40 years. A large earthquake drill in Mexico City is carried out annually on the anniversary of the great Mw 8.0 September 19th 1985 earthquake. On September 19th 2017 a magnitude 7.1 occurred on the 32nd anniversary of the 1985 earthquake a few hours after the city wide earthquake drill. The earthquake mechanism corresponds to a reverse faulting mechanism characteristic of earthquakes that occur on or near the plate boundary between the Cocos and North American Plates. USGS focal mechanism solutions indicate that rupture occurred on a shallowly dipping (i.e., 18.0°) thrust fault. The rupture of this earthquake is located approximately between the rupture of the great Mw8.0 September 19, 1985 to the South and the rupture of the great Mw8.0 October 9, 1995 to the North. The earthquake produced a small tsunami with a maximum measured wave amplitude of 1.7m in the port of Manzanillo. Three deaths were reported as a result of the main shock, one of them a minor who was severely injured and subsequently died in the hospital as a result of the injuries. Additionally, two other persons in Mexico City died as result of an aftershock on September 22nd: one from injuries to the head when she fell on the stairs and another as a result of a heart attack. Several hundred injuries were reported as a result of the main earthquake.
