YOGYAKARTA - Mount Merapi on the border of the Special Region of Yogyakarta and Central Java on Monday at 00.00 to 06.00 WIB launched incandescent lava up to 13 times to the southwest with a maximum sliding distance of two kilometers.
Head of the Geological Disaster Technology Research and Development Center (BPPTKG) Hanik Humaida said. During the observation period, Mount Merapi also experienced 29 earthquake avalanches with an amplitude of 4 to 28 mm for 20 to 164.6 seconds and one earthquake gust with an amplitude of 3 mm for 21.5 seconds.
According to the BPPTKG, on Monday, April 11 morning, it was observed that there was low pressure white smoke from the crater with moderate intensity as high as 10 to 20 meters above the summit of the crater of Merapi.
During the observation period on Sunday, April 10, at night from 18.00 to 24.00 WIB, Mount Merapi launched nine incandescent lava avalanches to the southwest with a maximum sliding distance of two kilometers.
Based on the results of morphological analysis from April 1 to 7, 2022, no significant changes in the height of the dome were observed on the southwest dome of Merapi and no significant morphological changes were observed in the middle dome.
According to BPPTKG, during that period the volume of the lava dome in the southwest was recorded at 1,672,000 cubic meters and the volume of the middle dome of 2,582,000 cubic meters. Until now BPPTKG still maintains the status of Mount Merapi at Level III or Standby.
Lava flows and hot clouds from Mount Merapi can impact areas in the south-southwest sector which include the Boyong River (a maximum of five kilometers) and the Bedog, Krasak, Bebeng rivers (a maximum of seven kilometers).
In addition, lava flows and hot clouds from Mount Merapi can impact areas in the southeastern sector which include the Woro River (a maximum of three kilometers) and the Gendol River (a distance of five kilometers).
If the volcano experiences an explosive eruption, then the ejection of volcanic material can reach an area within a radius of three kilometers from the top of the mountain. This was reported by Antara.
