A 7.6-magnitude undersea earthquake struck off the eastern coast of the Philippines late today, killing at least one person in a house collapse, and a second temblor struck about half an hour later, according to the US Geological Survey. Media reported that power was knocked out in several cities and roads and bridges were destroyed . A tsunami alert originally was issued for several countries including the Philippines, Indonesia, Palau, Japan and for Pacific islands as far away as the Northern Marianas, but was eventually lifted, the Pacific Tsunami Warning Center said. The centre said that very small tsunami waves of 3 centimetres were recorded along the eastern Philippine coast near Legazpi city and another nearby location. Benito Ramos, a retired general who heads the country's disaster-response agency, said in an advisory broadcast nationwide that residents should be on the alert for aftershocks. "Don't sleep, especially those in the eastern seaboard...because there might be aftershocks," he said. Initial warnings of a possible substantial tsunami prompted many coastal residents in the Philippines to head for high ground. "My neighbours and I have evacuated. We are now on our way to the mountains," fisherman Marlon Lagramado told The Associated Press before the warnings were lifted, in a telephone interview from the coastal town of Guiwan in the Philippine province of Eastern Samar, which was closest to the epicenter.
