MOUNT Semeru in East Java, which has a height of 3,676 meters above sea level (masl), erupted again with an eruption height reaching 2 kilometers on Monday at 01.38 WIB in the morning. “The eruption of Mount Semeru occurred on Monday, January 8 2024, at 01.38 WIB. The height of the eruption column was observed to be around 2,000 meters above the peak (5676 meters above sea level),” said Semeru Volcano Observation Post Officer, Ghufron Alwi in written statement received in Lumajang. According to him, the ash column was observed to be white to gray in color with thick intensity towards the south. The eruption was recorded on a seismograph with a maximum amplitude of 23 mm and a duration of 146 seconds. Also read: Mount Lewotobi eruption, PVMBG urges residents not to take off masks. To observe the earthquake at Mount Semeru in the period Monday from 00.00-06.00 WIB, 18 eruption earthquakes were recorded with an amplitude of 11-22 mm, one hot cloud eruption earthquake with an amplitude of 20 mm. Mount Semeru also experienced five avalanche earthquakes with an amplitude of 5-10 mm, six gust earthquakes with an amplitude of 4-8 mm, two harmonic earthquakes with an amplitude of 3-5 mm, and two distant tectonic earthquakes with an amplitude of 12-18 mm.

Observed white smoke from the main crater with light to moderate intensity at a height of around 200-500 meters from the peak. The weather was clear until “cloudy, weak wind to the southwest,” he said. The status of Mount Semeru is still at level III or alert, so people are prohibited from carrying out any activities in the southeast sector along Besuk Kobokan as far as 13 km from the peak (center of the eruption). Beyond this distance, people are not permitted to carry out activities within 500 meters of the river bank (river border) along Besuk Kobokan because they have the potential to be affected by the expansion of hot clouds and lava flows up to a distance of 17 km from the peak. “People are also not allowed to move within a 5 km radius of the crater/top of Semeru Volcano because it is prone to the danger of throwing rocks (incandescence),” he said. Officials also appealed to the public to be aware of the potential for avalanche hot clouds (APG), lava avalanches and lava along the flow. rivers/valleys that originate at the peak of Semeru Volcano, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat as well as the potential for lava in small rivers which are tributaries of Besuk Kobokan.
