Then, the community is also expected to anticipate disturbances due to volcanic ash from the eruption of Mount Merapi and be aware of the dangers of lahars, especially when it rains around Mount Merapi.
"All tourism and mining activities in the river channel that originates at Mount Merapi in the Disaster-Prone Area (KRB) III are recommended to be temporarily stopped," he concluded.
