Mount Semeru, which is located on the border of Lumajang and Malang Regencies, East Java, experienced an eruption with an eruption as high as 900 meters above the peak on Monday at 21.20 WIB.

"The height of the eruption column was observed to be about 900 meters above the peak or 4,576 meters above sea level," said Mount Semeru Observation Post Officer Sigit Rian Alfian as reported by ANTARA, Monday, October 14.

According to him, the ash column was observed to be white to gray with thick intensity to the southwest, the eruption was recorded on a seismograph with a maximum amplitude of 21 mm and a duration of 118 seconds.

Previously, there was also an eruption of Mount Semeru on Monday at 16.10 WIB with a column height of ash observed about 500 meters above the peak and a column of ash was observed to be white to gray with thick intensity to the southwest. The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 110 seconds.

In the morning, at 06.18 WIB there was also an eruption of Mount Semeru with a height of about 600 m above the peak or 4,276 meters above sea level.

"The ash column was observed to be white to gray with thick intensity to the north and northwest. The eruption was recorded on the seismograph with a maximum amplitude of 21 mm and a duration of 103 seconds," he said.

The eruption of Semeru for the first time on Monday occurred at 02.47 WIB with a column height of ash observed about 500 meters above the peak. The ash column was observed to be white to gray with thick intensity to the north and northwest. The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 126 seconds.

Sigit said 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).

Beyond 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 km from the summit.

"People are also not allowed to move within a three km radius of the crater/peak of Mount Semeru because it is prone to the danger of throwing stones (lightning)," he said.

In addition, the public 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 which are tributaries from Besuk Kobokan. Created, the eruption is still ongoing.
