MEXICO CITY (AP) - The latest on the magnitude 7.2 earthquake that hit southern Mexico (all times local):
A U.S. Geological Survey expert says Friday's magnitude 7.2 earthquake in southern Mexico was not in the aftershock zone from an even more powerful 8.2 quake last Sept. 8.
Paul Earle says the latest quake was in Mexico's southern Pacific coastal region, which has seen several powerful quakes over recent decades, ranging from magnitude 7.1 to 8.4.
The deadliest quake in the region happened on Sept. 19, 1985, in Michoacan state, about 300 miles northwest of Friday's tremor. That quake knocked down buildings as far away as Mexico City and resulted in at least 9,500 deaths, 30,000 injured and 100,000 homeless.
The quake last Sept. 8 came just 11 days before a magnitude 7.1 tremor in central Mexico caused more than 300 fatalities and significant damage in the Mexico City area.
A magnitude 5.8 aftershock in southern Mexico has caused tall buildings in Mexico City to briefly shutter, about an hour after a 7.2 quake sent people running into the streets.
The U.S. Geological Survey says Friday's second tremor was centered near the earlier quake in Mexico's Oaxaca state.
The shaking jangled nerves in central Mexico, a region still jittery over a magnitude 7.1 earthquake on Sept. 19 that caused 228 deaths in the capital and 141 more in nearby states. Many buildings in Mexico City are still damaged from that quake.
