MANILA, Philippines — Amid reports of Taal-affected evacuees attempting to return home, the Philippine Institute of Volcanology and Seismology (Phivolcs) warned that peril remains in the second-most active volcano in the country.
“Nakatalaga pa din po ang Alert Level 4 (Alert Level 4 is still in effect),” Ma. Antonia Bornas, chief of Phivolcs’ Volcano Monitoring and Eruption Prediction Division, said in a press conference Thursday.
“Nandyan pa din po ‘yung posibilidad na magkaroon po ng biglaang pagsabog ng malakas ng main crater ng Taal.”
(The possibility of a sudden explosive eruption of Taal’s main crater is still there.)
Bornas said that with Taal’s ongoing unrest, a major threat that remains is the occurrence of a bay surge.

Evacuation a ‘political decision’
Phivolcs said that once a volcano is raised to Alert Level 1, they automatically give a “scientifically informed advice” to the concerned local government regarding evacuation.
“Hindi po natin sila pwedeng sabihan na hindi tama ginagawa niyo,” Bornas said, referring to local government units. “It’s not within our authority, our sphere of experience.”
(We cannot tell them that what they’re doing is wrong.)
According to her, the reason local governments have the arduous task of implementing evacuation is because there are other things to consider besides science, such as the needs of constituents and economic factors.
With this, Bornas called evacuation “a political decision.”
Furthermore, she stressed that Phivolcs remains firm on their advice to evacuate the Taal Volcano Island and high-risk areas within the 14-kilometer radius danger zone.

Bornas also said the growing impatience of some evacuees is understandable given the volcano’s prolonged activity and periods of lull. However, she asked for more patience.
“Bigyan po natin ng pagkakataon ang atin pong ahensya na pag-aralan ulit ng masusi kung ano pong ibig sabihin ng lull na ito,” she said.
(Please give our agency time to further study what this lull means.)
