Mexico City and Chilpancingo were particularly badly affected. It caused the deaths of between 54 and 160 people.https://www.ngdc.noaa.gov/nndc/struts/results?eq_0=4139&t=101650&s=13&d=22,26,13,12&nd=display https://web.archive.org/web/20170131185741/https://www.ngdc.noaa.gov/nndc/struts/results?eq_0=4139&t=101650&s=13&d=22,26,13,12&nd=display dead January 31, 2017 Comments for the 1957 Guerrero earthquake National Centers for Environmental Information 4 October 2019 A small tsunami was triggered but caused little damage.https://www.ngdc.noaa.gov/nndc/struts/results?eq_0=4139&t=101650&s=18&d=99,91,95,93&nd=display Comments on the 1957 Guerrero tsunami National Centers for Environmental Information 4 October 2019April 2025 medicmedic Tectonic setting The state of Guerrero lies adjacent to part of the Middle America Trench where the Cocos Plate is being subducted beneath the North American Plate. The convergence between these plates at this location is about 65 mm per year. There have been many large and destructive earthquakes in the past, such as the M 7.6 1911 Guerrero earthquake.Guerrero 2014 usb000pq41 M 7.2 - 33km ESE of Petatlan, Mexico 5 October 2019 cs1 The Guerrero seismic gap is a ca. 200 km long segment of the subduction interface, which has not had a large earthquake since the 1911 event. Although several slow earthquakes have been observed in that time interval, an earthquake in the range M 7.9–8.0 could still be expected within the Guerrero gap.Lowry A.R. Larson K.M. Kostoglodov V. Samchez O. 2005 The fault slip budget in Guerrero, southern Mexico https://www.researchgate.net/publication/228369320 Geophysical Journal International 200 1–15 Earthquake The earthquake originally had an estimated magnitude of 7.9 s yes. This was recalculated by the International Seismological Centre in their ISC-GEM catalogue as 7.6 w. The duration of strong shaking was recorded as 90 seconds in Mexico City. The earthquake is thought to have ruptured the plate interface at the southeastern end of the Guerrero seismic gap. Damage The greatest damage was observed in Mexico City, where many buildings were destroyed, including the Angel of Independence, whose structure collapsed and its angel fell. Chilpancingo was also badly affected with 90% of buildings being damaged. The towns of Ayutla, Chilapa, Huamuxtitlán, San Luis Acatlan, San Marcos, Tlapa and Huitzuco all sustained significant damage.
