– Another minor eruption of Mount Semeru in East Java occurred on Wednesday
(2/3/2022) at 10:16 p.m. local time. It spews volcanic ash whose height of the
column was approximately 1,000 meters above the peak.
The Volcanological
Survey of Indonesia’s Officer at Mount Semeru Observation Post, Mukdas Sofian,
reported that the volcanic column was observed to be gray in color with thick
intensity and moved to the southeast. This eruption was recorded on a
seismograph with a maximum amplitude of 22 millimeters and a duration of 1,200
seconds.
On Thursday
(3/3/2022) morning from midnight till 6 a.m. local time, the volcanic
activities of Mount Semeru were observed to be decreasing. The volcano is
currently on alert level III, and locals are prohibited from carrying out
activities in the southeast sector along Besuk Kobokan within a radius of 13
kilometers from the summit. They are also advised strongly not to get within
500 meters from the riverbank along Besuk Kobokan because it can potentially be
affected by the eruption of volcanic clouds and lava that flows up to 17
kilometers from the summit.
In addition, they
are also prohibited from doing activities within the radius of 5 kilometers
from the crater of Mount Semeru due to the potential hazard of incandescent
rocks, volcanic clouds, and lava avalanches as well as lahars along the rivers
whose headwaters are on the summit of Mount Semeru, especially in Besuk Kobokan,
Besuk Bang, Besuk Kembar, and Besuk Sat. Residents are also advised to be aware
of the potential lahars that may flow along the tributaries of Besuk Kobokan.
