The Center for Volcanology and Geological Hazard Mitigation (PVMBG) has confirmed that Mount Semeru remains at Level III (Alert) status. Based on the latest evaluation, the volcanic activity of the tallest mountain on Java Island is still dominated by surface processes, but the potential for eruption remains a real threat to the surrounding areas.
Authorities have strictly forbidden residents and tourists from carrying out activities in the designated disaster-prone zones. Real threats such as hot cloud avalanches, lava flows, and volcanic material ejections can occur suddenly without significant early warning.
In addition to the risk of eruption, residents living along the rivers originating from Mount Semeru are asked to increase preparedness for lahar floods. High rainfall risks washing down volcanic materials deposited on the mountain slopes, which could threaten the safety of settlements and infrastructure along the river paths.
As a mitigation measure, local governments and related parties have been instructed to conduct intensive monitoring and expand safety dissemination to residents. The public is also urged to remain calm, refer only to official information channels, and not be easily influenced by unverified rumors regarding the volcanic activity.
