The incident prompted a review of the system.[12] EarthquakeAccording to the National Seismological Service (SSN) of Mexico, the epicenter was located in the Gulf of Tehuantepec, about {{convert|137|km}} southeast of Tonalá, Chiapas.[16] The United States Geological Survey (USGS) reported that the epicenter was about {{convert|87|km}} southwest of Pijijiapan, Chiapas.[13] The hypocenter was about {{convert|45|km|mi}} underground, deeper than usual for a relatively new subduction zone.[18] The SSN reported a measurement of M 8.2,[14] while the USGS also reported a M 8.2 earthquake after correcting an earlier estimate of M 8.0.[15] The earthquake was a result of normal faulting within the Cocos Plate with a displacement of up to {{convert|10|m|ft|0}}.[16][17] The entire thickness of the lithosphere of the Cocos Plate ruptured during the earthquake.[18] The earthquake is the most powerful to be measured in Mexico since the 1985 Mexico City earthquake,[19][20] and is comparable to the 1932 Jalisco earthquakes.[21] Mexican President Enrique Peña Nieto called the earthquake the "largest in at least a century" and claimed that it was felt by 50 million people.[10][22] Geophysicists at the National Autonomous University of Mexico speculated that the earthquake relieved stored pressure in the "Tehuantepec gap", making future earthquakes in the region less likely.[23] TsunamiA tsunami with waves of {{convert|1|m|ft|abbr=on}} and higher was generated by the earthquake and was recorded at Salina Cruz;[24] A tsunami wave of {{convert|1.75|m|ft|abbr=on}} was reported in Chiapas.[25] The Pacific Tsunami Warning Center issued a warning for the entire Pacific coast of Central America, also extending south to Ecuador.[26][27] AftershocksIn the hour following the earthquake, at least 12 aftershocks were recorded by the USGS.[28] As of 00:30 September 14 (UTC Time), the National Seismological Service (SSN) has recorded at least 1,806 aftershocks, of up to a magnitude of 6.1.[3] {{Gallery|title=2017 Chiapas earthquake and aftershocks |width=300 |align=center |File:2017 Chiapas earthquake - SSN.svg |alt1= |Graph of earthquakes by magnitude |File:2017 Chiapas earthquake map - SSN.svg |alt2= |Map of earthquakes as of 13 September Red marks earthquakes over {{M|w}} 8.0 and orange over {{M|w}} 5.0. |File:2017 Chiapas earthquake aftershocks - SSN.svg |alt3= |Number of aftershocks }}

Trump's delayed call, which he blamed on cellular signal problems, was criticized by some media outlets in both countries.[42] See also{{GeoGroupTemplate}}{{Commons category|2017 Chiapas earthquake}}
