Mayon Volcano Remains at Alert Level 3 as Lava Flows and Seismic Activity Persist

The volcano has experienced continuous lava effusion and frequent seismic activity, prompting regional travel disruptions and heightened monitoring efforts.

What is Mayon Volcano’s Current Alert Level?

As of June 2023, Mayon Volcano remains under Alert Level 3, which indicates “increased volcanic unrest” and a “high risk of hazardous eruptions.” This classification, issued by PHIVOLCS, follows 178 consecutive days of lava flow from the volcano’s crater, as reported by GMA Network. The agency emphasized that the alert level reflects ongoing “lava fountaining, ash emissions, and ground deformation,” with authorities advising nearby communities to avoid the volcano’s immediate vicinity.

How Has the Volcanic Activity Affected Travel?

The prolonged eruption has led to significant travel disruptions across the Philippines, particularly in the Bicol region, where Mayon is situated. According to Inquirer.net, local airports and roads near the volcano have faced periodic closures, while airlines have rerouted flights to mitigate risks from ash clouds. PHIVOLCS has not issued warnings for cross-border effects, focusing instead on domestic safety protocols.

What Are the Seismic and Lava Flow Trends?

Seismic activity at Mayon has remained consistent, with frequent tremors and volcanic earthquakes recorded by PHIVOLCS. The lava flow, which began in early April 2023, has extended beyond the crater, creating new fissures on the volcano’s slopes. “The lava is advancing at a slow rate, but its persistence underscores the need for continued vigilance,” said a PHIVOLCS scientist. The agency has also noted increased sulfur dioxide emissions, a common precursor to more explosive eruptions.

Why Is This Eruption Significant?

This prolonged activity has been characterized by sustained lava effusion. Experts note that the extended activity could indicate a “calm before a storm,” as prolonged effusion sometimes precedes more violent eruptions. “We are monitoring for any signs of increased explosivity,” said PHIVOLCS Director.

What Are the Next Steps for Authorities?

PHIVOLCS has maintained a 6-kilometer permanent danger zone around Mayon, with additional restrictions during periods of heightened activity. The Philippine government has also deployed emergency response teams to nearby municipalities, while local governments have conducted evacuation drills. “We are preparing for all scenarios, but our priority is the safety of residents,” said Department of the Interior and Local Government Secretary Benjamin Abalos.
