MANILA, Nov. 9 (Xinhua) -- The Philippine Institute of Volcanology and Seismology (Phivolcs) is warning the villagers living near the slopes of Mt. Bulusan in Northern Philippines's Sorsogon province of an imminent threat of lahar flows after heavy rains poured Monday evening, local newspaper Philippine Daily Inquirer reported Tuesday.

Phivolcs is suggesting those who are living in the villages of Gogon in Irosin, Anog in Juban and San Juan in Casiguran towns in Sorsogon move to safer grounds when river channels become swollen as these areas are prone to lahar flows once heavy rains hit, the report said.

By Monday, the Casiguran Disaster Risk Reduction and Management Council had already evacuated 34 families from the Casiguran town who were living near the designated permanent danger zone.

"Bulusan Volcano's seismic network detected a total of eight volcanic earthquakes during the past 24 hours," Phivolcs said in a bulletin issued Tuesday morning.

The volcano began spewing ash and steam on early Saturday and had another ash explosion Monday morning, which Philvocs said are typical of Mt. Bulusan's activity during its restive period.

Alert Level 1 has been hoisted over the area and Phivolcs expect more ash explosions to occur in view of the volcano's recent reactivation.

Areas within four kilometers of the summit has been designated a Permanent Danger Zone which means that villages located within the area may be affected by sudden steam explosions.

Phivolcs has advised the people residing near valleys and streams to be vigilant against sediment-laden stream flows in the event of heavy and continuous rainfall.

"Phivolcs is closely monitoring Bulusan Volcano's activity and any new significant development will be immediately (reported)," it said.

Mt. Bulusan, with a height of 1,565 meters, is the highest peak in Sorsogon. Covering a land area of 3,672 hectares, the mountain has recorded at least 17 major eruptions since 1886.
