The comments here are stupid. I actually RTFA in protest. Here is a summary provided by SMMRY:
A tsunami warning was initially issued for Mexico and other nearby countries, but later lifted.
The quake, which struck at 23:50 local time on Thursday, was felt hundreds of miles away in Mexico City, with buildings swaying and people running into the street.
BBC in depth - Earthquakes A history of deadly earthquakes Can earthquakes be predicted? Twenty-three people are reported dead in Mexico's Oaxaca state, 17 of them in the town of Juchitán, state Governor Alejandro Murat said.
The Pacific Tsunami Warning Center had originally said that tsunami waves of more than 3m were possible along the coasts of Mexico, with threats also facing El Salvador, Guatemala, Honduras and Costa Rica.
Panic on the streets BBC's Lourdes Heredia The earthquake has brought back memories of the tremor of 1985, which left massive destruction in Mexico City and a death toll of 10,000.
At magnitude 8.2, the quake outstrips the deadly 1985 tremor that hit close to Mexico City and caused thousands of deaths.
Mexico is currently also being threatened on its eastern coast by Hurricane Katia.
