BPPTKG Head Hanik Humaida said that during the observation period, the volcano has also experienced 28 earthquakes with an amplitude of 3-9 mm for 13-110 seconds, three gust earthquakes with an amplitude of 3-4 mm for 9-22 seconds, and three multi-phase earthquakes with an amplitude of 3-6 mm for seven seconds.
Based on observations on Sunday morning, crater smoke did not come out of the mount.
However, based on observations on Saturday from 00.00 a.m. to 24.00 p.m. local time, Mount Merapi released hot clouds as far as 1,800 meters in the southwesterly direction to the upper reaches of Krasak and Boyong Rivers.
The BPPTKG still maintains the status of Mount Merapi at Level III or Alert.
The lava and hot clouds of Mount Merapi are forecast to impact areas comprising Kuning, Boyong, Bedog, Krasak, Bebeng, and Putih in the south to the southwest.
In the meantime, Mount Merapi's volcanic material could disperse as far three kilometers from the mountain's peak.
