Kanlaon after the Philippine Institute of Volcanology and Seismology (Phivolcs) raised the possibility of phreatic eruptions on Monday. Zeaphard Caelian, head of the Provincial Disaster Management Program Division, said the active volcano's seismicity has decreased to only 17 volcanic quakes as of 8 a.m. on Tuesday. A day earlier, some 21 volcanic quakes were recorded, while from 5 a.m. on June 30 to 2 p.m. on July 3, at least 41 volcanic tremors were monitored caused by movements or eruptions of magma. "Mt. Kanlaon is still at Alert Level 1 or low-level unrest. Although there is a possibility of a phreatic eruption because of the hydrothermal activity, with the presence of water and magma," Caelian added. However, the volcano's sulfur dioxide gas emission has not increased, remaining at 151
