[3] This was an intraplate earthquake in the Cocos plate, with a normal-faulting mechanism.

The maximum slip was about 2.5 m, which was located about 20 and 40 km WNW of the hypocenter.

[4][5] The maximum intensity reached MM VIII in southwestern Oaxaca, and could be felt strongly in Mexico City.

[6] The torrential rains and flooding preceding and following the temblor intensified the damage of this earthquake.
