JAKARTA — A 7.2-magnitude undersea earthquake struck western Indonesia, off the island of Sumatra, on Friday at 1:30 p.m. (0630 GMT), but there were no threats of a tsunami, the climatology and meteorological agency said, according to DPA. The agency said the quake struck at a depth of 19 kilometers, about 150 kilometers southwest off Nias Island, near the western coast of North Sumatra province, and 1,339 kilometers south-west of Jakarta. The quake jolted local residents who fled their houses in panic, said Hiramo, a spokesperson of the West Nias regency disaster mitigation agency. There were no immediate reports of any casualties from the quake. But the German Research Center for Geosciences (GFZ) said the earthquake of magnitude 6.6 struck off the northwest coast of Indonesia’s Sumatra island on Friday. The quake was at a depth of 10 km (6.21 miles), GFZ said. Indonesia’s weather and geophysics agency, BMKG, put the quake at 7.2 magnitude and at a depth of 19 km but said it had no potential to trigger a tsunami wave. On Dec. 26, 2004, a 9.1 magnitude quake off the coast of northwest Sumatra triggered a tsunami that killed more than 230,000 people in Indonesia, Sri Lanka, India, Thailand and nine other countries, according to Reuters. A Twitter user, Siska Sasmita, said Friday’s quake was felt strongly in Padang city on Sumatra’s west coast. “We ran outside the house because the quake was felt for a pretty long time,” said Goris Tukan, a resident of Nias island, off Sumatra. He said no damage were seen in his neighborhood. Disaster mitigation agency official Filifo Daili said the quake was felt for 20 seconds and authorities were still collecting information about its impact. — Agencies
