Map: 6.4-Magnitude Earthquake Strikes off the Coasts of Mexico and Guatemala

A strong, 6.4-magnitude earthquake struck in the Pacific Ocean near the Mexico-Guatemala border on Sunday, according to the United States Geological Survey.

The temblor happened at 7:39 a.m. Eastern about 11 miles southwest of Brisas Barra de Suchiate, Mexico and about 120 miles west of Guatemala City, data from the agency shows.

As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

Aftershocks in the region

An aftershock is usually a smaller earthquake that follows a larger one in the same general area. Aftershocks are typically minor adjustments along the portion of a fault that slipped at the time of the initial earthquake.

Quakes and aftershocks within 100 miles

Aftershocks can occur days, weeks or even years after the first earthquake. These events can be of equal or larger magnitude to the initial earthquake, and they can continue to affect already damaged locations.

Source: United States Geological Survey | Notes: Shaking categories are based on the Modified Mercalli Intensity scale. When aftershock data is available, the corresponding maps and charts include earthquakes within 100 miles and seven days of the initial quake. All times above are Eastern. Shake data is as of Sunday, May 12 at 7:56 a.m. Eastern. Aftershocks data is as of Sunday, May 12 at 1:40 p.m. Eastern.
