TRIBUNBATAM.id - Mount Merapi on the border of the Special Region of Yogyakarta (DIY) and Central Java again released hot clouds of avalanches up to two kilometers to the southwest on Saturday (8/14/2021) at 07.40 am.
"Hot cloud avalanches were recorded on a seismogram with an amplitude of 60 mm and a duration of 158 seconds," said Head of the Geological Disaster Technology Research and Development Center (BPPTKG), Hanik Humaida, Saturday (8/14).
During the observation period from 00.00 to 06.00 am, Hanik explained, Mount Merapi was recorded four times spewing incandescent lava with a maximum sliding distance of 1,200 meters to the southwest.
The active volcano was also detected as experiencing 60 avalanches with an amplitude of 3-55 mm for 7-113 seconds, three gusts earthquakes with an amplitude of 3-4 mm for 12-13 seconds, one hybrid/multi-phase earthquake with an amplitude of 13 mm for 7 seconds, and four shallow volcanic earthquakes with an amplitude of 35-70 mm for 8-16 seconds.
Previously, Hanik said that Mount Merapi is currently entering the extrusion phase or the phase of magma coming out of the mountain's surface.
Mount Merapi has experienced an increase in seismic activity since April 2021 but its seismic activity then decreased on August 6, 2021.
The decrease in seismic activity marks the start of the magma extrusion phase.
Until now, the status of the volcanic activity of Mount Merapi is still at level III or Alert. (*)
