LUMAJANG - Mount Semeru which has a height of 3,676 meters above sea level (masl) experienced two eruptions on Saturday morning, namely 08.14 WIB and 08.22 WIB with an eruption height of 400 meters to 500 meters above the peak.

"There was an eruption of Mount Semeru at 08.14 WIB with an eruption observed about 500 meters above the peak or 4,176 meters above sea level (masl)," said Mount Semeru Observation Post Officer, Liswanto, as reported by ANTARA, Saturday, November 23.

According to him, the ash column was observed to be white to gray with moderate intensity to the southwest. When the report was made, the eruption was still ongoing.

The second eruption of Mount Semeru occurred at 08.22 WIB with an eruption column height of about 400 meters above the peak or 4,076 meters above sea level.

"The ash column was observed to be white to gray with moderate intensity to the southwest. When the report was made, the eruption was still ongoing," he said.

The highest volcanic activity on the island of Java is still dominated by earthquake eruptions based on officers' observations on Friday (22/11) recorded 115 times with an amplitude of 10-22 mm, and an earthquake length of 61-148 seconds.

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 activities 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 kilometers from the summit.

"People are also not allowed to 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.
