Two powerful earthquakes struck Venezuela on Wednesday, killing at least 32 people and injuring 700 after dozens of buildings collapsed ​into piles of shattered concrete and steel in and around the capital Caracas. A magnitude 7.2 earthquake hit about 160 km (100 miles) west of Caracas, followed less than a minute later by a magnitude 7.5 tremor, according to the U.S. Geological Survey (USGS).
