The 2017 Chiapas earthquake struck at 23:49 CDT on 7 September (local time; 04:49 on the 8th UTC) in the Gulf of Tehuantepec off the southern coast of Mexico, near state of Chiapas, approximately 87 kilometres (54 mi) southwest of Pijijiapan (alternately, 101 kilometres (63 mi) south-southwest of Tres Picos),[4] with a Mercalli intensity of IX (Violent).[5] The magnitude was estimated to be Mw 8.2.[6]

The earthquake caused some buildings in Mexico City to tremble, prompting people to evacuate.[5] It also generated a tsunami with waves of 1.75 metres (5 ft 9 in) above tide level;[7] and tsunami alerts were issued for surrounding areas.[8] Mexico's president called it the strongest earthquake recorded in the country, in a century.[9] It was also the second strongest recorded in the country's history, behind the magnitude 8.6 earthquake in 1787,[10] and the most intense recorded globally in 2017.[11]

Tectonic setting

The Gulf of Tehuantepec lies above the convergent boundary where the Cocos Plate is being subducted below the North American Plate at a rate of 6.4 cm/yr (2.5 in/yr).[12][13]
