Kanlaon Volcano Shows Increased Activity with Multiple Ash Emissions Events
Volcanic activity in Negros Island has intensified, with Kanlaon Volcano experiencing a higher number of ash emission events compared to the previous day. The latest updates from the Philippine Institute of Volcanology and Seismology (PHIVOLCS) provide a detailed account of recent volcanic unrest.
Recent Ash Emissions Events
PHIVOLCS recorded three ash emission events lasting up to 52 minutes on Thursday. This observation marks an increase from the two similar occurrences noted on Wednesday. These emissions produced moderate plumes reaching heights of up to 100 meters.
The ash plumes, influenced by prevailing wind directions, drifted south-southwest and southwest. In addition to these ephemeral ash discharges, the volcano has shown consistent degassing interspersed with sporadic ash emissions.
Volcanic Earthquakes: A Closer Look
Over 16 volcanic earthquakes were detected at Kanlaon Volcano on Thursday, including six volcanic tremors of varying durations, stretching up to 52 minutes. Notably, there was a decline in activity compared to the 20 reported earthquakes on Wednesday, one of which lasted for an hour and 32 minutes.
Continued Edifice Inflation
The volcano’s edifice remains inflated, indicating ongoing geological processes. PHIVOLCS warns that these signs are indicative of magmatic intrusion to shallow levels of the volcano’s structure, increasing the likelihood of an eruption.
Alert Level 3 in Effect
Currently, Alert Level 3 is in effect for Kanlaon Volcano, signifying a high level of volcanic unrest. This status suggests a significant risk of hazardous eruptions within several weeks.
Timeline and Previous Eruptions
Historical context highlights the volcano’s potential danger. On December 9, an explosive eruption occurred at Kanlaon Volcano’s summit vent. The eruption generated a substantial plume that reached an altitude of 4,000 meters. Ashfall and pyroclastic density currents (PDCs) were also documented during this event.
Understanding Potential Hazards
Given the current conditions at Kanlaon Volcano, it is crucial to understand the potential hazards that could arise from an eruption. These include sudden explosive eruptions, lava flow, ashfall, PDCs, rockfall, and lahars—torrential flows of mud, rock, and water—especially during heavy rainfall.
To safeguard nearby communities, the volcano’s danger zone has been expanded to a radius of six kilometers from the summit crater.
Staying Informed and Making Preparations
For those living within or near the danger zone, staying informed about PHIVOLCS updates and following safety guidelines is paramount. Evacuation plans should be developed, and necessary supplies should be prepared in advance.
By staying vigilant and adhering to official recommendations, the risks associated with volcanic activity can be minimized.
Conclusion
The increasing number of ash emissions and volcanic earthquakes at Kanlaon Volcano underscores the need for continued monitoring by PHIVOLCS. Given the volcano’s unrest and the potential for hazardous eruptions, public awareness and preparedness are essential.
