The Indonesian island volcano Anak Krakatau continues to be explosively active and produces volcanic ash. The VAAC Darwin reports ash at 2400 m altitude. MIROVA recorded a weak thermal anomaly with a power of 3 MW and seismic activity is elevated. Unfortunately, there are no longer any usable LiveCam images, because the ash erupted yesterday has soiled the camera.
The VSI recorded 18 seismic signals caused by explosive eruptions. The longest lasted 62 minutes. Harmonic tremors were also recorded. Already at the beginning of the month the earthquakes increased with a low frequency and indicated that magma was moving underground. Further eruptions can be expected.
GAK erupsi, ini proses biasa & ttp tenang, jauhi dr rad 2km. Erupsi proses biasa, keluarkan material tanda aktif, bhw GAK sdg tumbuh. Saksikan fenomenanya adalah hal luar biasa. (Sumber HPI Banten).@vulkanologi_mbg @PRB_BNPB@Kemenpar_RI @infomitigasi

The eruptions started on 29 December 2019, and initially the volcano increased its activity and erupted phreatic. In the evening, glowing tephra and volcanic ash was also produced.
