The 1995 Chiapas earthquake occurred on October 20 at 20:38 local time. The epicenter was located in Ocozocoautla de Espinosa, in the state of Chiapas, Mexico, near Tuxtla Gutiérrez.[2] It had a magnitude of Mw 7.2,[3] or ML 6.5.[4] Building damage was reported. Around 70 people were reported injured. In Tuxtla Gutiérrez, telephone and electricity services were momentarily interrupted.[5] This earthquake could be felt strongly in Mexico City and in many parts of southern Mexico. It could also be felt in Guatemala and El Salvador.[6] The centroid mechanism is of thrust faulting with a small strike-slip component. The rupture of this earthquake propagated from NW to SE over a distance of about 30 km. The duration of the rupture was about 17 seconds.[7] The earthquake was resulted from the internal deformation of the Cocos plate, which is subducting beneath the North American plate.[8]
