Volcanic activity at Mount Semeru, located on the border of Lumajang and Malang regencies, has shown another increase. On Monday (6/7) morning at 05:13 WIB, Java's highest volcano was reported to have erupted, spewing a column of ash approximately 1,000 meters above the peak.
According to a report from the Mount Semeru Observation Post, the thick grey volcanic ash material is moving northwards. The eruption was recorded on the seismograph with a maximum amplitude of 22 millimeters and a duration of 167 seconds. Currently, Mount Semeru's status remains at Level III (Alert).
Volcano monitoring authorities strictly prohibit the public from engaging in any activities within a five-kilometer radius of the main crater. This preventive measure is taken due to the high risk of incandescent rock ejection, which poses a threat to local residents' safety.
Additionally, residents and sand miners are urged to refrain from any activity within a 13-kilometer radius in the southeastern sector along Besuk Kobokan. Outside this radius, people are still prohibited from approaching within 500 meters of the riverbanks along the lahar flow route, to anticipate the threat of pyroclastic flows and cold lahar flows that could occur at any time.
Increased education and extra vigilance are expected along the river basins originating from Mount Semeru, including Besuk Bang, Besuk Kembar, and Besuk Sat. The public is asked to constantly monitor official information from relevant agencies to ensure safety amid fluctuating volcanic activity.
