A powerful earthquake hit the southeastern coast of Mexico in the state of Oaxaca on Tuesday.

The temblor struck at about 11:30 a.m., according to the U.S. Geological Survey, which said the quake had a preliminary magnitude of 7.7 but has since been adjusted to 7.4. The earthquake was a relatively shallow 26 kilometers deep. Typically, the closer an earthquake is to the surface the more damage it can cause. Shaking could be felt as far away as Guatemala and El Salvador.
