Multiple eruptions at Mount Semeru in East Java, Indonesia, on February 13 and 14, 2026, produced pyroclastic flows up to 6 km (3.7 miles) down the volcano’s southeastern flank and ash plumes up to 2 000 m (6 500 feet) above the crater. PVMBG maintains a 13 km (8 miles) exclusion zone in the southeastern sector.
A slow-moving landslide has damaged hundreds of homes in Padasari village, Tegal, Central Java, Indonesia, forcing large-scale evacuations since early February 2026. Local reporting indicates that ground deformation remains active, preventing residents from returning to affected areas.
A series of collapse-fed pyroclastic density currents descended the Mi-isi Gully at Mayon volcano, Philippines, on February 9, 2026, with the farthest runout reaching 4 km (2.5 miles) from the summit crater. The activity peaked between 10:35–11:37 local time (LT), culminating in a seven-minute event at 10:59 LT that generated ash clouds exceeding 2 km (about 6 560 feet) in height and causing ashfall across parts of Camalig and Guinobatan, Albay, during rainy conditions.
At least nine people have been reported dead, while over 80 remain missing, in Indonesia after a major landslide destroyed homes and forced evacuations in the Pasir Langu village on January 24, 2026.
