Mount Semeru Experienced 8 Eruptions Followed By Eruptions Of Up To 700 Meters

JATIM - Mount Semeru was recorded as having eight eruptions accompanied by eruptions with an altitude of up to 700 meters above the peak of Mahameru on Sunday morning from 00.00 to 10.00 WIB.

"The ash column was observed to be white to gray with moderate intensity to the southwest. When the report was made, the eruption was still ongoing," said Mount Semeru Observation Post Officer Liswanto in a written statement received in Lumajang, Sunday, November 10, which was confiscated by Antara.

He explained that the first eruption occurred at 00.10 WIB, but the visual eruption was not observed and when the report was made, the eruption was still ongoing. Then it did not take long to revive the eruption at 00.25 WIB with an eruption height observed about 400 meters above the peak.

Furthermore, the eruption occurred again on the highest mountain on the island of Java, which was 00.37 WIB, at 04.36 WIB, at 05.22 WIB, then at 05.28 WIB with an eruption height was observed up to 700 meters above the peak or 4,376 mdpl.

"There was another eruption at 06.27 WIB with the eruption being observed as high as 600 meters above the peak. The ash column was observed to be white to gray with thick intensity to the west. The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 116 seconds," he said.

Then there was an eruption at 09.45 WIB, but the visual eruption was not observed and the eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 100 seconds.

He explained that Mount Semeru is still on alert status, so the Center for Volcanology and Geological Hazard Mitigation (PVMBG) provides a number of recommendations, namely that people are prohibited from carrying out any activity in the southeast sector along Besuk Kobokan as far as eight kilometers from the summit (the center of the eruption).

Then outside of that distance, people are not allowed to carry out activities at a distance of 500 meters from the riverbank (river border) along Besuk Kobokan, because it has the potential to be affected by the expansion of hot clouds and lava flows up to a distance of 13 kilometers from the summit.

"People should also not move within a three-kilometer radius of the crater/peak of Mount Semeru, because they are prone to the danger of throwing stones-lights," he said.

In addition, the public also needs to be aware of the potential for hot clouds, lava avalanches, and rain lava along rivers/valleys that originate at the top of Mount Semeru, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat, as well as the potential for lava in small rivers that are tributaries from Besuk Kobokan.
