Activity of Anak Krakatau, Ibu and Taal.

Several eruptive episodes occurred today April 22, 2002 at Anak Krakatau.

The first at 00:49 WIB, with an ash plume, black and thick, observed at ± 500 m above the summit (± 657 m above sea level). This eruption was recorded on a seismograph with a maximum amplitude of 37 mm and a duration of 79 seconds.

A second episode occurred at 01:45 WIB, with a black ash plume observed ±600 m above the summit (±757 m above sea level). This eruption was recorded on a seismograph with a maximum amplitude of 30 mm and a duration of 48 seconds.

A third is noted at 02:37 WIB, accompanied by a thick, black ash plume, observed ± 1500 m above the summit (± 1657 m above sea level) dispersed to the southwest. This eruption was recorded on a seismograph with a maximum amplitude of 60 mm and a duration of 45 seconds.

Mount Ibu, in the Moluccas archipelago, erupted on Friday April 22, 2022 at 08:37 WIT, with a column of gray ash observed at ± 1500 m above the peak (± 2825 m above sea level). the sea). This eruption was recorded on a seismograph with a maximum amplitude of 28 mm and a duration of 70 seconds.

In the past 24 hours, the Taal volcanic network recorded 6 volcanic earthquakes, including 5 volcanic tremor events lasting 2 minutes to fifty-four, 1 weak volcanic earthquake and background tremor low intensity that has persisted since April 20, 2022.

Mirova reports low to moderate thermal anomalies for the past three days, ranging between VRP 3 and 18 MW.

Activity at the main crater was dominated by the generation of 1500 meter high plumes that drifted southwest. Sulfur dioxide emissions averaged 6,042 tonnes/day on April 21, 2022.

Maximum temperatures of 63.7°C were last measured from Main Crater Lake on February 25, 2022.

Based on ground deformation parameters from electronic tilt, continuous GPS, and InSAR monitoring, Taal Volcano Island and the Taal area began to deflate in October 2021.

Alert Level 2 (decreasing unrest) prevails over Taal Volcano. DOST-PHIVOLCS reminds the public that at Alert Level 2, sudden steam-driven or phreatic explosions, volcanic earthquakes, ash fall, and deadly accumulations or explosions of volcanic gas may occur and threaten areas inside TVI and along its coast. Entry into TVI, Taal's permanent danger zone, must therefore be strictly prohibited.
