Based on the morphological analysis of Merapi for the period 23-29 February 2024, he said the morphology of the southwest dome of Mount Merapi was observed to change slightly due to lava avalanche activity, while the morphology of the middle dome was relatively fixed.
Meanwhile, the analysis of air photos on January 10, 2024 showed the volume of the southwest dome of Mount Merapi was measured at 2,663,300 cubic meters and the middle dome was 2,358,400 cubic meters.
Until now, BPPTKG still maintains the status of Mount Merapi on the border of Central Java and DIY at Level III or Alert.
To anticipate the potential danger of the eruption of Mount Merapi, BPPTKG appealed to the public not to carry out any activities in areas of potential danger.
The lava fall and hot clouds from Mount Merapi can have an impact on areas in the south-southwest sector which include the Boyong River (a maximum of five kilometers) and the Bedog, Krasak, and Bebeng rivers (a maximum of seven kilometers).
