JAKARTA - Mount Semeru, which has a height of 3,676 meters above sea level (masl), erupted again with an eruption column height observed about 600 meters above the peak on Saturday, at 07.54 WIB.

The officers of the Semeru Volcano Observation Post (PPGA) on Mount Sawur, Sigit Rian Alfian, in his written report said that there was an eruption of Mount Semeru with an eruption of about 600 meters above the peak or about 4,276 meters above sea level.

"The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 89 seconds. The ash column was observed to be white to gray with a thick intensity to the east," he said in a written report on Mount Sawur, Lumajang Regency, East Java, quoted from Antara, Saturday, February 11.

The activity of Mount Semeru on Saturday, 00.00-06.00 WIB was recorded visually as clear, crater smoke was not observed, sunny to cloudy weather, and weak winds to the north.

Observations of the seismicity were recorded 21 earthquakes with an amplitude of 16-22 mm, two gusts with an amplitude of 5-9 mm, and three volcanic earthquakes with an amplitude of 10-15 mm.

Mount Semeru is still on Alert status or level III, so the public is advised to comply with a number of recommendations submitted by the Center for Volcanology and Geological Disaster Mitigation (PVMBG).

People are prohibited from carrying out any activities in the southeast sector along Besuk Kobokan as far as 13 km from the summit (the center of the eruption).

Outside this distance, the community is also 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 17 km from the summit.

"The public is also advised not to move within a 5 km radius of the crater/peak of Mount Semeru because it is prone to the danger of throwing stones (pijar)," he said.

In addition, he continued, the public is also advised to be aware of the potential for hot clouds of avalanches (APG), lava avalanches, and lahars along rivers/valleys that originate at the peak of Mount Semeru.

"Especially as long as Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat and the potential for lahars in small rivers which are tributaries of Besuk Kobokan," he said.
