PHIVOLCS: No lahar flow despite heavy rains due to Mario, habagat

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) clarified Friday that there was no hyperconcentrated lahar flow in a village near Mayon Volcano amid heavy rainfall brought by typhoon Mario and enhanced southwest monsoon.

 

In Isay Reyes' report on 24 Oras, it was explained that the "lahar flow" was actually lahar deposits, which was brought by the knee-deep overflow of a bridge in barangay Maipon in Guinobatan after it rained hard in Albay on Thursday.

The village is one of the usual routes of the lahar flow; hence, it is full of lahar deposits. 

 

Evacuation update 

 

Residents who are affected by the Mayon Volcano continue their evacuation from their homes Friday. In barangay Salvacion in Sto. Domingo, some evacuees even started to build makeshift homes near evacuation sites.

Other evacuation centers have started to set up medical stations. 

 

PHIVOLCS earlier raised Alert Level 3 at Mayon, prompting thousands of residents to evacuate earlier this week. Alert Level 3 means that "hazardous eruption" is possible within weeks. 

 

At this stage, those who are residing at the 6-km radius Permanent Danger Zone (PDZ) around Mayon and the seven-kilometer Extended Danger Zone (EDZ) on the southeaster flank are advised to evacuate due to rock dalls, landslides, sudden explosions, or dome collapse that may generate volcanic flows. 

 

As of 8 a.m., PHIVOLCS  noted 22 volcanic earthquakes and 70 rockfall events at Mayon for the past 24 hours. —NB, GMA News
