Then the highest mountain on the island of Java erupted again at 03.24 WIB with an eruption column height of 800 meters above the peak, and the eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 117 seconds.

Furthermore, the eruption continued and visually several eruptions of Mount Semeru when the eruption was not observed because it was covered in fog, but officers appealed to the public to be aware of the activity of the mountain which has a height of 3,676 meters above sea level.

Liswanto explained, 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).

Furthermore, outside this 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.
