AlQa'dah 15, 1432, Oct 13, 2011, SPA -- Indonesia's resort island of Bali was struck by a 6.2 magnitude earthquake on Thursday, shaking buildings and sending tourists running out of hotels. There were no immediate reports of any casualties, according to Reuters. The epicentre of the quake was about 100 miles (160 km) southwest of the island's capital Denpasar, the U.S. geological survey said. Caroline Mercier, a 40-year-old tourist in the island's cultural centre of Ubud, said she was used to feeling quakes in California, but never like this one. "It started at my feet and went all though my heart and head -- it made me nauseous. My first reaction was to get out of the house. I was very confused when the roof started shaking," she told Reuters. Novotel Bali Benoa, one of the many resorts in the luxury southern beach area of Nusa Dua, evacuated its guests as the hotel shook for a minute. "The funny thing is that the foreign guests who were sitting in the lobby did not feel the shaking. They started running when hearing people say 'there's an earthquake' while running down the lobby," hotel worker Ariyanti told Reuters. Endro Tjahjono, head of information at Bali's meteorology agency, said there was no tsunami potential and no reports of aftershocks. Cracks appeared in the walls and glass lobby windows of his office in the southern town of Kuta, and some top floor ceilings fell off, he said. Indonesia is on the Pacific's "Rim of Fire" and gets regular earthquakes.
