Yet another phase of lava fountaining, or paroxysms, is almost certainly about to start now. Volcanic tremor has started to rise sharply from low to now already high levels, and strombolian activity at the eastern vent of the New SE crater is becoming more and more intense and near-continuous.
The 5th paroxysm in a row and within a single week comes after a slightly longer interval, approx. 48 hours, than the very regular roughly 35 hours intervals between each of the previous four events.
Given that the last one was very intense compared to the first three, it might not be surprising. Maybe the time to recharge or reproduce the right conditions deeper below for a new gas-rich batch of fresh magma to start rising just took a bit longer.
