PHIVOLCS: No quakes at Taal in 24 hours but rising plumes monitored; alert level 2 stays

(Eagle News) — No volcanic earthquakes were monitored at Taal in 24 hours. The Philippine Institute of Volcanology and Seismology said the upwelling of hot volcanic fluids in the lake of the volcano, which remains on alert level 2, however, generated plumes that reached 1.5 kilometers tall. PHIVOLCS said the plumes drifted to the north-northwest. Sulfur dioxide was also monitored, and  averaged 2,811 tons on May 22. “Temperature highs of 71.8°C and pH of 1.59 […]
