Taal Volcano has remained on alert level 1 since 23 November 2005. However, due to the recent anomalous changes in monitored parameters such as: the crater temperature, the number of volcanic earthquakes detected per day, and the intensification of steaming activities, Philippine Institute of Volcanology and Seismology (PHIVOLCS) has increased the level of alert to a level 2. This change to level 2 simply means that the magma inside the volcano is rising which could eventually lead to an eruption.
PHIVOLCS announced to the general public that the Main Crater remains off-limits because hazardous steam-driven explosions may occur, along with the possible build-up of toxic gases. Areas with hot grounds and steam emission such as portions of the Daang Kastila Trail are considered hazardous. PHIVOLCS reminds everyone that the whole Volcano Island is a Permanent Danger Zone (PDZ) and permanent settlement within this area is strictly prohibited. Currently, 9 Batangas towns have been put on alert: Agoncillo, San Nicolas, Sta. Teresita, Laurel, Lemery, Talisay, Tanauan City, Balite and Mataas na Kahoy.
According to the Regional Disaster Coordinating Council (RDCC), if conditions continue and Taal Volcano is placed on alert level 3, then it will be time for authorities to activate contingency plans and enforce the evacuation of residents.
