Mayon, the Philippines most active volcano, with 48 historical eruptions is restive. Over the weekend, tremors, lava fountaining, and lava collapse events has been noted. Government volcanologists report that “relatively high level of unrest as magma is at the crater and hazardous eruption is possible within weeks or even days.”

The authorities has prohibited the public from entering the 6 kilometer-radius Permanent Danger Zone (PDZ), and the 7-km Extended Danger Zone (EDZ) on the southern flanks “due to the danger of rockfalls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows.”

Yesterday morning, we appealed for help to map the 6-kilometer Permanent Danger Zone of Mayon, and the community responded quickly. Today, it’s been 100% mapped, 57% validated (and still on-going). Thank you! The names of the generous mappers may be found in the project dashboard.

Mayon Permanent Danger Zone (PDZ): 100% mapped. 57% validated.

Today, a new project to map the 7-kilometer Extended Danger Zone (EDZ) around Mayon has been published: https://tasks.hotosm.org/project/4037 and we are again appealing for some of your precious time, and valued mapping skills, to map the EDZ. Most especially the priority tasks in the southern quadrant, where there are a number of villages and settlements.

Again, this is preemptive mapping activity to assist local government agencies and aid organizations to support future damage assessment. We call on the digital humanitarian community for their assistance for this project.
