Earthquakes shook a broad swath of southern Mexico on Tuesday, causing buildings to sway in the capital and sending thousands fleeing into the streets as quake alarms sounded. But there were no immediate reports of damages or injuries. According to AP, the U.S. Geological Survey said a magnitude-5.5 quake hit at 7:04 a.m. (9:04 a.m. EDT; 1304 GMT), centered about 10 miles (17 kilometers) west-southwest of Pinotepa Nacional on the Pacific Coast and 227 miles (365 kilometers) south-southeast of Mexico City. Mexico Seismology Service initially calculated the quake's magnitude at 5.9. A second quake struck near the same spot eight minutes later, also setting off alarms in the capital and causing people to evacuate tall buildings in the capital. The USGS calculated the magnitude of that quake at 5.1.
