A magnitude 7.3 earthquake struck off the coast near the Mexico-Guatemala border. The U.S. Pacific Tsunami Warning Center issued a warning that a tsunami up to 1 meter high could hit the coasts of Mexico and Guatemala, but no casualties have been reported so far. The Guatemalan president said disaster authorities are responding to the situation and urged citizens to remain calm. This earthquake occurred about three weeks after a series of strong earthquakes hit northern Venezuela on September 24th.
