At the cone, several vents remain active with near-continuous pulsating ash-rich lava fountains, as well as intermittent stronger explosions, generating an ash plume rising approx. 2 km today. Most of the erupted lava is directly entering the lava tube system from the lower vents.
Volcanic tremor has increased again compared to yesterday, but still remains lower than the average of the past weeks. Whether its amplitude corresponds to the lava output rate is in parts speculation; visually, the latter seems to be reduced at the moment.
The lava flows did not advance significantly over the past 24 hours, with nearly all activity occurring along the southern margins of the active flow field.
Trade winds today are carrying the ash plume, approx. 2 km high, towards the SW over the ocean, which is good for the airport on the east side to be operational.
During the past 24 hours, 119 quakes of magnitudes from 2.3 up to 3.7 maximum have been registered under the volcano as of this update. Larger ones have been absent since the 5.1 event yesterday morning, but this can of course change again quickly.
