Based on visual observations, white smoke of moderate to thick intensity appeared, reaching 100 meters high above the crater’s peak.
The BPPTKG maintains the status of Mount Merapi at Level III or Alert. The potential danger due to the eruption of Merapi is estimated to be within a maximum radius of five kilometers from the summit.
Tourism, climbing, and mining activities in rivers, whose upstream are located on the slopes of Mount Merapi, are recommended to be put on hold. (INE)
