Mayon Volcano in the Philippines' Albay province emitted lava fountains and ash plumes that rose five kilometers into the air this week [1].
The ongoing activity poses a significant risk to local populations, forcing thousands of residents to seek shelter and placing tens of thousands more on high alert [3, 4].
The Philippine Institute of Volcanology and Seismology (PHIVOLCS) and local authorities are monitoring the volcano as the eruption entered its 83rd day [2]. This period of activity is characterized as an effusive eruption, which generates sustained lava flows and consistent ash emissions [2].
Reports on the nature of the activity vary. Some accounts said the lava pouring from the crater was a gentle eruption, while other reports said there was a thunderous explosion that ejected a huge column of lava fragments and smoke [3, 4]. Regardless of the intensity, the environmental impact has been severe, with ash clouds turning the sky dark in surrounding areas [1].
Local authorities have warned tens of thousands of people to remain ready to flee their homes [4]. Thousands of villagers have already returned to evacuation centers as the volcano continues to spew material [3]. The activity was reported on Monday and overnight, with further lava fountaining observed on Tuesday [1, 3].
PHIVOLCS continues to track the volcano's behavior to determine if the eruption is stabilizing or escalating. The sustained nature of the event—now spanning nearly three months—has created a prolonged state of emergency for the province of Albay [2].
“Ash plume rose five kilometers into the air”
The extended duration of this effusive eruption indicates a prolonged period of instability for Mayon Volcano. While some activity is described as gentle, the scale of the ash plumes and the necessity for mass evacuations suggest that the volcanic system remains highly active. The long-term displacement of thousands of residents highlights the vulnerability of Albay province to recurring geological hazards.
