Mount Semeru, which is on the border of Lumajang and Malang Regencies, East Java, erupted again with an eruption height of 500 meters above the peak on Saturday afternoon.

"There was an eruption of Mount Semeru at 15:14 WIB with an eruption column height of about 500 meters above the peak or 4,176 meters above sea level (masl)," said Mount Semeru Observation Post Officer Mukdas Sofian in a written report received in Lumajang.

According to him, the volcanic ash column of Mount Semeru 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 115 seconds," he said.

Based on officer data, he said, Mount Semeru was recorded as having an eruption five times on Saturday, which was 00.59 WIB with visual eruptions not being observed, then the second eruption occurred at 05.09 WIB with an eruption height of 400 meters above the peak.

The third eruption occurred at 09.39 WIB with the visual of the eruption not being observed, but was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 122 seconds.

The fourth eruption occurred at 13.45 WIB with an eruption column height of 300 meters above the peak with a column of volcanic ash white to gray with thick intensity to the southwest and the fifth eruption occurred at 15.14 WIB.

Mukdas explained that Mount Semeru is still on Alert or Level II status, so that 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).

Outside of that distance, he said, people are not allowed to carry out activities at a distance of 500 meters from the riverbank 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.

"The public is also advised not to move within a three-kilometer radius of the crater/peak of Mount Semeru, because it is prone to the dangers of incandescent stones," he said.
