Legazpi:The Philippine Institute of Volcanology and Seismology (Phivolcs) recorded an ash emission from Mayon Volcano at 822 a.m. on Tuesday. The volcano remains under Alert Level 3, indicating heightened unrest.

According to Philippines News Agency, the event involved minor Strombolian activity at the summit crater, producing a plume that rose 1,600 meters before drifting southwest. Cameras at the Mayon Volcano Observatory on Ligñon Hill and the Ligao Observation Station captured the plume.
