JAKARTA, Indonesia, Sept 28, 2018 (News Wires) - Powerful earthquakes jolted the Indonesian island of Sulawesi on Friday, destroying houses and killing at least one person. An official said widespread damage was expected. The US Geological Survey said the strongest of two major quakes had a magnitude of 7.5 and was centered at a depth of 6 miles (10 kilometers) about 35 miles (56 kilometers) northeast of the central Sulawesi town of Donggala. The quake briefly triggered a tsunami warning. An official with the local disaster agency, Akris, said "many houses have collapsed." "It happened while we still have difficulties in collecting data from nine villages affected by the first quake," he said. "People ran out in panic." Television footage showed people running into the streets. National Disaster Mitigation Agency spokesman Sutopo Purwo Nugroho said communications with the region are disrupted. The Donggala area, home to about 300,000 people, was hit earlier Friday by a magnitude 6.1 earthquake that based on preliminary information killed one person, injured 10 and damaged dozens of houses.
