In the past, Etna has been known for producing series of paroxysms at similar, surprising regular intervals. Obviously, the question now is whether the next one will follow this pattern or not. At the time of writing this post, tremor seems to be rising indeed, first sign that activity increases.
At the surface, the New SE crater seems to have sporadic mild explosions, with a light ash plume rising.
