The 1995 Chiapas earthquake occurred on October 20, 1995 at 20:38 local time (October 21, 1995 at 02:38 UTC). The epicenter was located in the state of Chiapas, Mexico, near Tuxtla Gutiérrez.[1] It had a magnitude of Mw 7.1,[2] or ML 6.5.[3] Building damage was reported. Around 70 people were reported injured. In Tuxtla Gutiérrez, telephone and electricity services were momentarily interrupted.[4] 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.[5] 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 s.[6] The earthquake was resulted from the internal deformation of the Cocos Plate, which is subducting beneath the North American Plate.[7]
