Observation of the plume by meteorological satellite

Ruang Volcano (725 m above sea level) is a volcanic island in the Sangihe Islands in Indonesia. In September 2002, a large-scale eruption occurred, sending plumes of smoke up to a height of approximately 20,000 meters.

Although the situation has calmed in recent years, an eruption of similar magnitude occurred on April 17, raising concerns. This eruption also appears to have sent volcanic smoke up to the top of the troposphere, and the volcanic plume was also confirmed by the Himawari 9 weather satellite.

Raised to alert level 4

The Philippine Institute of Volcanology and Seismology (PHIVOLCS) announced to the public the alert level for the eruptive activity of Taal Volcano on a scale of 0 to 5. PHIVOLCS gradually raised its alert level to 4 , the second highest level, at 8:30 p.m. Japan time.

Ash was detected in the area and local authorities issued an evacuation notice for Taal Volcano Island and the Agoncillo and Laurel areas in Batangas due to the risk of pyroclastic flows and tsunamis.

Depending on the volcanic smoke situation, planes might be affected.

If a large amount of volcanic ash is released into the atmosphere due to an eruption, it can have serious effects on flight operations, such as stopping the engines of planes inhaling it or damaging cockpit windows , making visibility difficult. risk of harm.

Depending on the state of future volcanic activity, it is possible that international flights connecting Eurasia and Oceania may need to be diverted, resulting in delays or other impacts.
