LEGAZPI CITY -- The Philippine Institute of Volcanology and Seismology (Phivolcs) raised the alert status around Mayon Volcano from Level 1 to Level 2 Friday morning after it observed intensified restiveness in the volcano.

This alert condition signifies a state of increasing unrest, which can lead to ash explosions or eventually an eruption, a Phivolcs bulletin said.
