of-Spain, Rabi'I 29, 1434, Feb 10, 2013, SPA -- A magnitude-5 earthquake has rattled Trinidad and Tobago, but no damage or injuries have been reported. The quake struck shortly after midnight some 55 miles (89 kilometers) from the twin-island nation's capital of Port-of-Spain. It also shook Grenada and parts of Venezuela's Caribbean coast, AP reported. The U.S. Geological Survey says the offshore quake's epicenter was 94 kilometers (58 miles) beneath the earth's surface. In Port-of-Spain, some jittery people lingered outdoors after the ground rattled buildings and hotels. Police say they received numerous calls from residents about the quake.
