A strong earthquake rocked parts of eastern Indonesia early Friday, killing 16 people, injuring more than 100 and damaging hundreds of buildings, seismologists and officials said. The magnitude-6 quake struck at 5:26 a.m. (2226 GMT Thursday) and was centered 30 kilometers (20 miles) off the eastern coast of Alor island, about 1,600 kilometers (1,000 miles) east of the capital Jakarta, said seismologist Rahmat Triono in Jakarta. It was followed by a magnitude-5 aftershock, he added.
