Another earthquake has rocked Mexico. The U.S. Geological Survey calculated the magnitude of Tuesday's quake at 7.1 and said it was centered about 75 miles southeast of Mexico City. Facades cracked on several buildings and scattered rubble in the streets of the capital. It also struck on the anniversary of the 1985 quake that killed more than 5,000 people.
Less than two weeks earlier, a 8.1 magnitude earthquake struck the country. The death toll from that temblor has reached more than 90.
