Mayon still on alert level 1 with 3 quakes, steam and sulfur dioxide emissions monitored

(Eagle News)–Three volcanic earthquakes were monitored at Mayon in 24 hours. Also monitored at the volcano, which remains on alert level 1, were steam and sulfur dioxide emissions, the Philippine Institute of Volcanology and Seismology said. PHIVOLCS said the  emission of white steam-laden plumes  was moderate. Sulfur dioxide emission, on the other hand, was last measured at 436 tons–below baseline average—on October 29. According to PHIVOLCS, “overall, the Mayon edifice is still inflated with respect […]
