MANILA - Lahar flowed down the slopes of Mount Mayon in Albay province amid heavy rains on Saturday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Sunday, as the active volcano remained on the brink of a hazardous eruption.
The lahar flow was observed in the Miisi river channel between 1 and 7 p.m. Saturday, Phivolcs chief Renato Solidum told reporters.
The river channel, which lies between Camalig and Daraga towns, had collected the highest amount of ash and lava fragments since Mayon first spewed ash on Monday, he said.
Rains have also caused a "sediment laden stream flow" that carried sand and rocks near the Santo Domingo bridge on Sunday, Solidum said.
The volcano has spewed ash and lava thrice on Sunday, as of 11 a.m., Phivolcs research specialist Abigail Pidlawan told ABS-CBN News website.
Alert level 4, a notch below the highest level, remained hoisted over Mayon, which means that a hazardous eruption is possible within days, Phivolcs said.
The restive volcano, known for its near-perfect cone shape, has already displaced more than 81,000 and caused overcrowding at temporary shelters, the country's disaster agency had said.
