A volcano in the Philippines has erupted for a second time this year, prompting emergency evacuations. Mt. Kanlaon is one of two dozen active volcanoes in the Philippines, which is located on the Pacific "Ring of Fire" where volcanic activity and earthquakes are common. The Philippine Institute of Volcanology and Seismology (Phivolcs) raised its alert level to 3 on a scale of 5 meaning there is an increased risk of lava flows. #volcano #lava #news #headline #earth #asia
