CAAP prohibits flights near Taal, Mayon

Metro Manila (CNN Philippines, June 5) — The Civil Aviation Authority of the Philippines has prohibited airplanes from flying within 10,000 feet of the surface of Taal and Mayon volcanoes amid their unrest.

It advised pilots to avoid flying close to the volcanoes' summit as ash from sudden phreatic eruptions can be hazardous.

The Philippine Institute of Volcanology and Seismology earlier raised the alert over Mayon Volcano to Alert Level 2 due to an increase in rockfall from the volcano’s summit lava dome.

Meanwhile, Taal Volcano remained at Alert Level 1. However, latest reports showed an increased degassing activity in the volcano, which produced steam-rich plumes that rose 3,000 meters above Taal Volcano Island.

This created volcanic smog or vog over Taal Caldera, which affected the municipalities of Balete, Laurel, and Agoncillo in Batangas.
