#Himawari satellite data in the @NOAA/@UWCIMSS VOLCAT system show the onset of the #Epi eruption at ~18:30 UTC on Jan 31, with colors indicating the presence of SO₂ in the #volcanic cloud.
Potential #infrasound detection from the #Epi eruption detected on @CTBTO infrasound array IS22 in New Caledonia. The first detection arrives around 18:40 UTC. The signal features very low frequency content, mostly between 0.03-0.14 Hz.
SO₂ emissions from #Epi clearly detected in #Sentinel5P#TROPOMI data on February 1. SO₂ amounts are low (~1-2 kilotons) but part of the plume appears to have reached mid-tropospheric altitudes, indicating a fairly energetic #eruption. @CopernicusEU@BIRA_IASB
Scenes from Tongatapu... Lots of dust, damage and clean up to do! But generally calm and stable. People are ready to get to it. Praise God we are still standing. #Tonga#TongaVolcano#tongatsunami
