A magnitude 7.3 earthquake in northeastern Indonesia left one person dead and four injured when it rattled buildings, causing panicked residents to flee homes, and shopping malls, officials and witnesses said Monday. The woman who died suffered a heart attack, apparently triggered by the shock of Sunday's powerful quake, and one of those hurt broke his leg after jumping from the fourth floor of a building, said a doctor in Manado, a regional capital on Sulawesi island. The U.S. Geological Survey put the earthquake at magnitude 7.3 and the Indonesian seismological institute issued a tsunami alert via television and radio, but the feared wave never came. The quake struck 10 kilometers (six miles) beneath the Molucca Sea and was centered 130 kilometers (80 miles) from the Maluku capital of Ternate and 2,200 kilometers (1,400 miles) northeast of the national capital, Jakarta, the USGS was quoted as saying by the Associated Press.
