The Philippine Volcanology and Seismology cautioned the public about the possible volcanic sediment flows and lahars at Albay province's Mayon Volcano amid the onslaught of tropical storm "Paeng."

The state seismology bureau disclosed that heavy rains prevailing over the Bicol Region and Eastern Visayas until the weekend due to severe tropical storm "Paeng" could also generate muddy stream flows or muddy runoff in rivers and drainage areas within the Mayon volcano.

It also strongly recommends increased vigilance and readiness of communities in Mayon's pre-determined zones of lahar and related hazards.
