Since the violent re-start of activity on Monday evening, the eruption has been going on with more or less stable lava output from the vent, and volcanic tremor has been stable. During this morning, a tendency of increasing activity seems to be manifesting itself.
Interestingly, more quakes have started to occur again, mostly at 10-15 km depth under the central part of the volcano. There were 6 quakes of magnitude 3.0 or above and 21 quakes between 2.0 and 3.0. The latest magnitude 3+ quake occurred only 1.5 hours ago, at 11.13 a.m., and was felt again by the local population.
Inflation and ground deformation have picked up as well during the past 12 hours or so, after they had been leveling out in the days before.
What could all this mean? We cannot say for sure, but one possible interpretation could be that the quakes and inflation reflect new magma intruding at depth, from where it might connect to the shallower system and further supply the eruption. It could also lead up to new vents forming, depending on how effective the currently active magma feeding system is to counteract the building pressure underground.
The next days will likely be very interesting to follow!
