Batangas, PH - There are four phreatomagmatic bursts on Thursday, July 8, at 6:47 am, 6:06 pm, 9:21 pm, and 9:50 pm
A new
series of phreatomagmatic bursts occurred at Taal Volcano in Batangas on Thursday,
July 8.
The
Philippine Institute of Volcanology and Seismology (Phivolcs) said the first
phreatomagmatic burst occurred at 6:47 am and generated a grayish plume 200
meters high.
This
was followed by three more phreatomagmatic bursts at 6:06 pm, 9:21 pm, and 9:50
pm.
On Wednesday, July 7, Phivolcs had also observed a brief phreatomagmatic eruption at 5:18 am, followed by five phreatomagmatic bursts within the day.
A
phreatomagmatic eruption, or an eruption involving the interaction of magma and water, had
prompted the declaration of Alert
Level 3 for Taal Volcano a week ago, on July 1.
Phivolcs
said on Thursday morning that the volcano's sulfur dioxide (SO2) emission
remains high, averaging at 11,397 tons per day on Wednesday. It was at 7,560
tons per day on Tuesday, July 6.
The
current all-time high for SO2 emission is 22,628 tons per day, recorded last Sunday,
July 4.
A
volcano emits SO2 when magma is relatively close to the surface.
Phivolcs
also said on Thursday morning that steam-rich plumes rose 1,500 meters high
from Taal's main crater over the past 24-hour period.
During
that period as well, there were 60 volcanic earthquakes, including:
5 explosion-type earthquakes
24 low-frequency volcanic earthquakes
21 volcanic tremor events lasting 2
to 4 minutes
10 hybrid earthquakes
There was also "low-level background tremor" that ended at 6:21 pm on Wednesday but resumed at 9:52 pm, added Phivolcs.
Phivolcs has been warning that an
explosive eruption is possible under Alert Level 3.
There could be pyroclastic density currents, which are
clouds of hot gas, ash, and other volcanic debris. A volcanic tsunami is also
possible since Taal Volcano is situated within Taal Lake.
Taal Volcano Island, Taal Lake, the
barangays of Bilibinwang and Banyaga in Agoncillo town, and the barangays of
Buso-buso, Gulod, and Bugaan East in Laurel town remain high-risk areas.
Some residents who fled their homes
but are staying outside designated evacuation centers have been struggling to get food and other necessities these
past days.
