LEGAZPI CITY, ALBAY, Philippines — The local government of Camalig in Albay province has begun preparing for the return of 204 families displaced by Mt. Mayon’s unrest as volcanic activity continues to ease, although authorities stressed that no decampment order has been issued yet.

The preparations came after the Philippine Institute of Volcanology and Seismology (Phivolcs) reported a sustained decline in Mayon’s activity, marked by fewer volcanic earthquakes, the absence of active lava effusion, and lower sulfur dioxide (SO2) emissions since the third week of July.

“We are still closely monitoring all parameters. If this decreasing trend is sustained, we may consider lowering the alert status to alert level 2,” Doreen Abelinde, officer in charge of the Mayon Observatory, told the Inquirer on Wednesday.
