On Wednesday, Mount Semeru in East Java erupted, sending ash and gas more than 13 kilometers (8 miles) away and raising the alert level to its highest status, Level IV. The eruption led to the evacuation of nearly 1,000 residents from surrounding villages and the rescue of 178 climbers, who had become stranded during their ascent, according to thejakartapost and channelnewsasia.

The climbers were camping at Ranu Kumbolo, a location approximately 6.4 km from the crater, when the eruption occurred. Officials confirmed that all climbers and their guides are reported safe. “The situation is under control,” affirmed Septi Wardhani from Semeru National Park. The area is noted for its natural beauty but is also recognized for the risks associated with volcanic activity, as Semeru is one of Indonesia's highest peaks, standing at 3,676 meters (12,060 feet), according to Al Jazeera and AA.

Following the eruption, authorities deployed rescue teams to assist in the evacuation efforts. Over 900 individuals moved to temporary shelters established in schools and mosques. Local officials reported there were no immediate casualties, despite ash and rock debris damaging homes and infrastructure in nearby communities, as detailed by thejakartapost and channelnewsasia.

Many residents reported experiencing shock and trauma from the event, reminiscent of previous deadly eruptions that have plagued the area. The last significant eruption in December 2021 resulted in numerous fatalities and widespread destruction. Authorities have assured residents that they are continuously monitoring the volcano's activity as the situation evolves, emphasizing the need for preparedness in this seismically active region, according to Al Jazeera and AA.
