Back-to-back powerful earthquakes have slammed Venezuela, collapsing buildings in the capital of Caracas. The U.S. Geological Survey said the first earthquake had a magnitude of 7.1 and its epicenter was west of the community of Morón, located along the country’s Caribbean coast, about 168 kilometers west of Caracas. The quake had a depth of 22 kilometers. Minutes later, the USGS reported an even larger 7.5-magnitude earthquake. The second quake had a depth of 10 kilometers and its epicenter was 16 kilometers southwest of Morón. The quakes are among the strongest to strike Venezuela in more than a century.
