Mount Semeru, located on the border of Lumajang and Malang Regencies, East Java, has once again shown a significant increase in volcanic activity. According to the latest data from the Center for Volcanology and Geological Hazard Mitigation (PVMBG), the highest volcano on Java Island recorded seven explosive eruptions within just four hours.
The eruptions spewed ash columns of varying heights, between 400 and 1,300 meters above the peak. This phenomenon indicates an increase in magma pressure below the surface, drawing serious attention from volcanologists and relevant authorities in disaster mitigation efforts.
The impact of this activity is starting to be felt by residents living on the mountain slopes, with reports of volcanic ashfall spreading up to several dozen kilometers from the eruption site. As a preventive measure, the local government has activated emergency preparedness protocols and urged the public to remain calm yet vigilant regarding any developments.
The Geological Agency of Indonesia highlighted the importance of continuous monitoring of seismic activity and ground deformation around Mount Semeru. Given the mountain's history of frequent eruptions, residents in high-risk zones are advised to prepare self-evacuation plans and continuously monitor official information from relevant agencies to minimize the risk of casualties and material losses.
