A restive volcano in central Philippines briefly erupted Tuesday, spewing a 4.5-kilometer (2.8-mile) ash plume and debris into the sky as its rumblings were heard nearby. The Philippine Institute of Volcanology and Seismology said a moderately explosive eruption occurred at the summit crater of Kanlaon Volcano before dawn, lasting five minutes based on seismic and infrasound data. Ash fell in at least nine villages southwest of the volcano on Negros island, but no injuries or damage was reported.
