Mayon Volcano Activity Overview and Latest Seismic Data

The latest continuous monitoring of Mayon Volcano reveals a stable emission pattern with volcanic activity remaining at moderate alert level. Ground observation reports indicate persistent steam and ash venting from the summit crater, accompanied by minor lava effusion visible during nighttime. Seismicity reflects a steady frequency of volcanic tremors alongside low-magnitude volcanic earthquakes, suggesting ongoing magma movement beneath the surface without immediate signs of escalation. Aviation authorities remain on alert as ash plumes reached an altitude of approximately 1.8 kilometers above the crater, affecting nearby flight paths and prompting precautionary advisories.

Seismic data from the last 24 hours include:

Volcanic tremors: 120 events
Low-frequency earthquakes: 35 events
Rockfall signals detected: 15 events
No significant ground deformation changes recorded

Parameter	Value	Remarks
Seismic events (24 hr)	170	Within normal range
Lava effusion	Active	Minor flow, nighttime visibility
Ash plume height	1.8 km	Above summit crater
Alert Level	3	Moderate unrest

Lava Flow Developments and Hazard Zone Updates

New eruptive activity at Mayon Volcano has resulted in significant advancements of lava flows primarily along the Bonga and Miisi channels. The latest thermal imaging indicates that lava has extended approximately 500 meters downslope in the past 24 hours, prompting renewed caution among local communities. The sluggish yet persistent flow has caused partial obstruction of drainage pathways, raising the risk of sudden overflow during heavy rains.

In response to these dynamic changes, the hazard zones have been adjusted to better reflect current dangers. Authorities have expanded the Permanent Danger Zone (PDZ) from 6 kilometers to 7 kilometers radius around the summit, specifically targeting high-risk barangays in the southern and southeastern sectors. Evacuation advisories remain in effect, with emphasis on the following high-alert areas:

Barangay Bonga – Closest to active lava front
Barangay Miisi – Adjacent to secondary lava channels
Barangay Mabinit – Increased ashfall and lahar threats

Hazard Zone	Previous Radius (km)	Updated Radius (km)	Primary Risk
Permanent Danger Zone (PDZ)	6	7	Lava flows, pyroclastic density currents
Extended Danger Zone (EDZ)	7-8	7-9	Ashfall, lahar flows
Increased Monitoring Zone	8-10	9-11	Volcanic tremors, ashfall

Emergency Preparedness and Evacuation Recommendations for Local Communities

Local authorities and community leaders are urged to maintain a high level of alert and closely monitor official announcements from the Philippine Institute of Volcanology and Seismology (PHIVOLCS). Residents within the 8-kilometer radius from the summit should prepare for immediate evacuation due to increased volcanic activity manifested by frequent ash emissions and occasional lava flows. It is essential to secure vital documents, stock up on emergency supplies, and identify safe evacuation centers ahead of time. Community volunteers and response teams must coordinate to ensure rapid assistance and clear communication channels during any evacuation process.

Safety drills and information dissemination must be intensified, particularly targeting vulnerable groups such as elders, children, and persons with disabilities. The following key actions are recommended for all households and local barangays:

Keep masks and goggles ready to protect against ashfall.
Clear drainage and waterways to prevent clogging by volcanic debris.
Establish pick-up points and transportation means for evacuation.
Maintain constant communication with evacuation coordinators via designated radio frequencies or social media groups.

Zone	Recommended Action	Evacuation Status
0-4 km	Immediate evacuation	Mandatory
4-8 km	Prepare evacuation kits Stay alert	Recommended
8-10 km	Monitor updates	Advisory

The Way Forward

In summary, the 24-hour observation of Mayon Volcano as of April 13, 2026, 12:00 AM reveals ongoing volcanic activity closely monitored by authorities. The data underscores the need for continued vigilance and preparedness among communities in the surrounding areas. Relief agencies and government units remain on alert, ready to respond to any escalation. As the situation develops, updates will be provided to keep the public informed and ensure safety measures are effectively communicated.
