Two days after a M6.2 deadly earthquake hit Sulawesi, Indonesia, the Semeru volcano erupted violently, ejecting hot cloud of ash and gas 4.5 kilometers (nearly 3 miles) in the sky.
The pyroclastic eruption took place at 17:24 local time on January 16, 2021.
The National Disaster Mitigation Agency warned people who live on the slopes of the highest volcano on Java (3,676 meters or 12,060 feet) to be vigilant and watch for furious lahars due to heavy rainfall.
Indonesia’s Volcanology and Geological Hazard Mitigation Center did not raise Semeru’s alert status, which already had been at the third-highest level since it began erupting in May.
