Taal’s emissions of sulfur dioxide fall but low frequency quakes persist


Despite fewer volcanic earthquakes and reduced sulfur dioxide emissions, a dangerous eruption in the Taal Volcano is still possible within hours to days, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said Wednesday morning.

8 a.m. to PHIVOLCS The newsletter suggested that the sulfur dioxide released by the volcano has further declined to an average of 153 tons per day.

The highest record was achieved at 5,299 tons per day on January 13, according to PHIVOLCS, adding that the presence of more sulfur dioxide in the atmosphere suggests that magma is already shallow or rising towards the volcanic surface.

Meanwhile, the Philippine Seismic Network (PSN) plotted only six volcanic earthquakes from 5 a.m. Tuesday till 6 a.m. Through Wednesday. The magnitudes ranged from 1.5 to 2.4 without any felt occurrence.

That brings the total number of volcanic earthquakes reported since Taal’s initial January 12 eruption to 725.
