Sunday, January 12, was the
beginning of a bad dream for residents of the province of Batangas, as well as the
rest of Region IV-B Calabarzon and parts of Metro Manila itself. Taal Volcano,
a complex volcano system in the middle of Taal Lake and also the second most-active
volcanic system in the Philippines, began to spew steam and ash in a powerful
eruption that has not been seen in decades. The surrounding areas have been
blanketed in ash, which has also caused health hazards and even shut down
flights in the Ninoy Aquino International Airport. But the crisis in Taal has
only just begun.
CNN Philippines reports that the eruption phase of Taal Volcano
that began at the start of this week is not yet on the verge of calming down.
Renato Solidum, head of the Philippine Institute of Volcanology and Seismology
(PHIVOLCS) said in a statement this Tuesday, January 14, that the ash eruptions
continue unabated and are even causing volcanic earthquakes around Taal Lake.
Thus far, the Alert Level 4 (intense unrest) status raised by the national
seismology agency remains in effect in anticipation of a large explosive
eruption at any time. Already Taal has experienced a “Strombolian” eruption
complete with lava fountain early Monday, January 13.
PHIVOLCS so far has recorded some
212 individual seismological earthquakes in the Taal area since Sunday, with 81
of them being strong enough to be felt without instrumentation, and reaching up
to Intensity 5 which indicates “strong shaking.” Meanwhile, the ashes and steam
being spewed by the volcano into the atmosphere has created its own weather conditions
over Calabarzon. A report from the Philippine Atmospheric, Geophysical and
Astronomical Services Administration (PAGASA) says the steam has generated
clouds capable of causing rains with plumes to pour.
According to PAGASA forecaster
Aldczar Aurelio, the rains resulting from Taal Volcano’s steam eruption will
further compound the low-visibility conditions being brought about by the
ongoing ash-fall. It will be enough to wash away ash deposits from affected
areas that have been covered with volcanic matter, but they might also lead to
mudflows as the ash-fall deposits are carried off. So far, only Batangas
province has declared a state of calamity in the wake of the Taal eruption. But
Cavite, Laguna, and Metro Manila have already been visited by volcanic ash
carried by the wind. PHIVOLCS is reckoning that the Taal Volcano eruption
period could last for as short as a few days to as long as a few months.
