PAGADIAN CITY (Mindanao Examiner / Nov. 3, 2012) – A powerful earthquake on Saturday shook the southern Filipino province of Surigao del Sur, but authorities reported no casualties or damage to structures.
The U.S. Geological Survey said the quake registered magnitude 6.1 and was traced about 87 kilometers from Butuan City. But a bulletin released by the Philippine Institute of Volcanology and Seismology said it recorded the earthquake at magnitude 6.5.
The earthquake did not trigger a tsunami warning, although it was one of the series shaking reported in the area and nearby province of Surigao del Norte.
The Philippines sits on the so-called Pacific Ring of Fire, a 40,000-kilometer area where large number of earthquakes, tremors and volcanic eruptions occur in the basin of the Pacific Ocean. It has more than 400 volcanoes and sometimes called the circum-Pacific seismic belt. (Mindanao Examiner)
