5.5 Magnitude Earthquake Shakes Mexico

According to the U.S. Geological Survey, an earthquake with a preliminary magnitude 5.8 struck Mexico on Tuesday morning. The quake has since been downgraded to a 5.5 magnitude.

The epicenter of the tremblor was located 11 miles southwest of Santiago Pinotepa Nacional, Mexico; 37 miles south-southeast of Ometepec, Mexico; and 231 miles south-southeast of Mexico City. It originated 6.2 miles deep, and struck at 7:04am. Mexico Seismology Service had initially calculated the quake's magnitude at 5.9.

A second quake struck near the same spot eight minutes later, which also set off alarms in the capital. The USGS calculated the magnitude of the second quake to be at 5.1.

Typically, earthquakes of this magnitude are felt across a wide area and may cause minor to moderate damage.

Buildings swayed, and thousands of people fled into the streets as earthquake alarms sounded. There were no immediate reports of damages or injuries.

Mexico City's soft soil and geology make it exceptionally sensitive to far away earthquakes.
