Inp.polri.go.id - Lumajang. The tremors of the cold lava flood of Mount Semeru occurred for about 1.5 hours due to heavy rains that flushed the peak of the volcano which has an altitude of 3,676 metres above sea level in Lumajang Regency, East Java, Monday.
The officer of the Semeru Volcano Observation Post at Mount Sawur, Ghufron Alwi, said on Monday (25/12/2023) that observations of the seismic activity of Mount Semeru on 25 December 2023 for the period 12 to 6 pm showed a flood tremor earthquake, antaranews.com..
The activity of the highest mountain on Java Island showed eruption earthquakes, two gusts as well as two distant tectonic earthquakes.
"For visual observation, the volcano is clearly visible until it is covered by fog. Crater smoke is not observed. The weather is sunny to rainy, weak to moderate winds to the north and northeast," Ghufron said.
Meanwhile, Head of Prevention, Preparedness and Logistics of Lumajang Wawan Hadi Siswoyo urge residents and sand miner to be vigilant when rain falls on Semeru peak
The status of Mount Semeru is at level III or alert, prohibiting people from doing any activities in the southeast sector along Besuk Kobokan as far as 13 km from the peak of the volcano.
Beyond that distance, people should not carry out activities at a distance of 500 metres from the edge of the river along Besuk Kobokan because it has the potential to be hit by the expansion of hot clouds and lava flows up to a distance of 17 km from the peak.
"People should also not do activities within a radius of 5 kilometres from the crater/peak of Semeru Volcano because it is prone to the danger of incandescent rock ejection," he said..
