Mayon volcano on Luzon island in the Philippines remains active, building up its lava dome. It has produced three lava flows, the longest of which has traveled a distance of 3.4 km. These flows follow the channels of Bonga, Mi-isi, and Basud. Yesterday, seven pyroclastic density currents were reported, covering a distance of up to 4 km. Additionally, 201 debris avalanches were recorded. An ash eruption was also observed, sending volcanic ash up to an altitude of 3000 m.
The seismic network of PHILVOLCS detected 100 volcano-related earthquakes. Among these, 58 were tremor phases caused by magma movements underground. Some of these tremors lasted up to 13 minutes, suggesting that the volcano does not intend to decrease its activity in the near future.
Gas emissions reached 1888 tons per day yesterday, which is a significant amount. Steam rose up to 800 m above the height of the dome.
Overall, ground deformation due to magma inflation is being observed. However, in the eastern part of the volcanic area, the opposite trend of deflation is occurring. It’s likely that the magma erupting at the dome currently originates from this sector.
Mayon is an active stratovolcano located on the island of Luzon in the Philippines. It is known for its nearly perfect cone shape and is one of the most iconic and picturesque volcanoes in the country.
