MOUNT MERAPI, Indonesia—Indonesia’s Mount Merapi erupted Saturday with avalanches of searing gas clouds and lava, forcing authorities to halt tourism and mining activities on the slopes of the country’s most active volcano.
Merapi, on the densely populated island of Java, unleashed clouds of hot ash and a mixture of rock, lava, and gas that traveled up to 7 kilometers (4.3 miles) down its slopes. A column of hot clouds rose 100 meters (109 yards) into the air, said the National Disaster Management Agency’s spokesperson Abdul Muhari.
