Mount Semeru This Evening Eruption With An Eruption As High As 800 Meters
LUMAJANG - Mount Semeru, which has a height of 3,676 meters above sea level (masl), erupted again with an eruption as high as 800 meters above the peak on Wednesday evening.
"There was an eruption of Mount Semeru at 17.19 WIB with an eruption column height of approximately 800 meters above the peak or about 4,476 meters above sea level," said Mount Semeru Observation Post Officer Yadi Yuliandi as reported by ANTARA, Wednesday, July 16.
According to him, the ash column was observed to be gray with moderate to thick intensity to the west. The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 140 seconds.
Based on officers' records, Mount Semeru previously erupted on Wednesday at 0613 WIB, but the eruption visual was not observed. The eruption was recorded on a seismograph with a maximum amplitude of 22 mm and a duration of 118 seconds.
He 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).

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.
"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.
He appealed to the public to be aware of the potential for hot clouds, lava avalanches, and rain lava along rivers/valleys whose water flows originate at the top of Mount Semeru, especially along Besuk Kobokan, Besuk Bang, Besuk Kembar, and Besuk Sat, as well as the potential for lava in small rivers which are tributaries from Besuk Kobokan.
