Mount Merapi Launches 13 Incandescent Lava Falls 1.8 Km

YOGYAKARTA - The Geological Disaster Technology Research and Development Center (BPPTKG) stated that Mount Merapi on the border of the Special Region of Yogyakarta and Central Java emitted 13 incandescent lava avalanches on Friday, April 8. ) to the southwest from 00.00 to 06.00 WIB. According to the Head of BPPTKG, Hanik Humaida during the observation period, Merapi also experienced 25 avalanches with an amplitude of 4-9 mm for 29-123 seconds, and one gust earthquake with an amplitude of 3 mm. for 17 seconds. On Friday morning, low pressure crater smoke was observed to be white with medium intensity and 50-75 meters high above the crater peak. On Thursday (7/4) night from 18.00 to 24.00 WIB, Mount Merapi also launched 21 times incandescent lava to the southwest. The maximum sliding distance of incandescent lava is 1.8 km. Quoted Between. based on the results of morphological analysis in the period 25-31 March 2022, it shows that there is an increase in the height of the southwest dome of about 4 meters due to avalanche activity. While the central lava dome is not observed any significant morphological changes.

The volume of the lava dome in the southwest is recorded at 1,672,000 cubic meters and the middle dome is 2,582,000 cubic meters. Until now BPPTKG still maintains the status of Mount Merapi at Level III or Siaga.
