Activity of Gunung Ibu, Semeru and Semisopochnoi.

An eruption of Gunung Ibu occurred in the Moluccas on Monday February 14, 2022 at 10:40 WIT with the height of the ash column observed at ± 1000 m above the peak (± 2325 m above sea level ). The ash column is observed to be gray with thick intensity to the west. This eruption was recorded on a seismograph with a maximum amplitude of 25 mm and a duration of 80 seconds.

Another eruptive episode occurred on February 13, 2022 at 3:38 p.m. WIT with the height of the ash column observed at ± 1000 m above the summit (± 2325 m above sea level). It is observed that the ash column is gray in color with a thick intensity towards the south. This eruption was recorded on a seismograph with a maximum amplitude of 28 mm and a duration of 60 seconds.

The activity level is at 2/waspada.
Communities around Mount Ibu and visitors/tourists are advised not to travel within the 2.0 km radius and the sector expansion is 3.5 km to the crater opening in the northern part from the active crater of Mount Ibu.

Semeru erupted on Java on Sunday February 13, 2022 at 08:15 WIB with the height of the ash column observed at ± 700 m above the summit (± 4376 m above sea level). It is observed that the ash column is white to gray with a thick intensity towards the southwest. This eruption was recorded on a seismograph with a maximum amplitude of 24 mm and a duration of 100 seconds.

The activity level is at 3 / siaga, with recommendations of:
1. Do not carry out any activity in the southeastern sector along Besuk Kobokan, up to 13 km from the summit (the center of the eruption). Beyond this distance, the community does not conduct activities within 500 meters of the bank (river edge) along Besuk Kobokan due to the potential for expansion of hot clouds and lava flows. lava up to a distance of 17 km from the summit.
2. Do not travel within 5 km of the crater/summit of Mount Semeru as it is subject to the danger of rock throwing (incandescent).

Near-continuous low-level eruptive activity continues at Mount Cerberus North Crater at Semisopochnoi. Seismicity remains high and several small explosions have been detected. A low-level ashy plume was observed in webcam data during the day yesterday and today.

Small eruptions producing minor ash deposits near the active north crater of Mount Cerberus and ash clouds generally within 3 km. above sea level have characterized recent activity. Small explosions and associated ash emissions may continue and be difficult to detect, particularly when heavy cloud cover obscures the volcano.
