Mount Semeru, which is on the border of Lumajang Regency and Malang, East Java, erupted again with volcanic ash eruptions as high as 900 meters above the peak, or 4,576 meters above sea level (masl).

"There was an eruption of Mount Semeru on Friday at 17.25 WIB, and the eruption was recorded on a seismograph with a maximum amplitude of 23 mm and a duration of 118 seconds," said Mount Semeru Observation Post Officer Sigit Rian Alfian as reported by ANTARA, Friday, August 30.

According to him, the column of volcanic ash was observed to be white to gray with thick intensity to the northeast and east.

Previously, the highest mountain on the island of Java erupted at 10.06 WIB with a column height of ash observed about 900 meters above the peak, and the ash column was observed to be white to gray with thick intensity to the east. The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 110 seconds.

He explained that the status of Mount Semeru at Level II or Alert, so that the Center for Volcanology and Geological Hazard Mitigation (PVMBG) provided a number of recommendations, namely that people are prohibited from carrying out any activities in the southeast sector along Besuk Kobokan, as far as 8 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 km from the summit.

The community is 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).

In addition, it is necessary to be aware of the potential for hot clouds, lava avalanches, and lahars along rivers/valleys that originate at the peak of Mount Semeru, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat, as well as the potential for lahars in small rivers that are tributaries of Besuk Kobokan.
