A magnitude 7.5 earthquake shook land 23 miles from Tecpan de Galeana, north of Acapulco, in Mexico at 8:27 a.m. local time.
No injuries have been reported as of 11 a.m. EDT.
The event was recorded by a seismologist and reportedly lasted for about 30 seconds.
According to the USGS, "Mexico is one of the world's most seismically active regions." This is because it sits atop three large tectonic plates, the movement of which causes the earthquakes and occasional volcanic eruptions for the country.
Aftershocks are expected to continue in the coming days. The National Weather Service's Pacific Tsunami Warning Center has declared that there is no widespread or destructive tsunami expected from this quake.
Aftershocks will not be as strong as the initial quake. Seismologists warn to be on the lookout for fires, as they are the greatest threat following an earthquake.
