(CNN) -- A strong earthquake measuring 6.5 in magnitude struck Saturday off the coast of western Indonesia, according to the U.S. Geological Survey's National Earthquake Information Center. The USGS told CNN there are no plans to issue any tsunami warnings. There are no reports of injuries or damage. The quake struck around 9 p.m. local time (9 a.m. ET) off the coast of Simeulue which is part of Aceh province. According to Indonesia's geological center, the temblor was felt only in the areas close to the epicenter, including the cities of Medan, Sibolga, and the island of Nias. Aceh was devastated after a 9.0 magnitude quake struck off its coast on December 26, 2004, triggering a massive tsunami that spread across the Indian Ocean, killing more than 170,000 people in a dozen countries-- CNN's Taffy H.
