Kilauea started up some interesting activity a few days ago, and has been expanding the show! The lava level is still high at the summit vent (Halema'uma'u). But the main show has moved to the active Pu'u O'o vent further away. The floor of this crater had two significant collapsing events overnight, which is linked to the underground magma movement down the rift from the vent. Nothing is showing on the surface at the moment, but instruments indicate ground deformation. Dozens, perhaps we're now up to hundreds, of small earthquakes are continuing to occur in the rift area. The largest so far was a 4.2.
What does all this mean? Well, it could mean simply that the pressure from the magma is breaking some of the underground layering of old lava and forcing its way into the new cracks, extending magma fingers deeper down the rift zone in the Puna district. Or it could mean that the pressure is continuing to build, the magma is being forced to find new outlets, and that there will be a surface eruption. No one knows.
People living in the Puna district have been warned to be on alert for an eruption. Will it happen? When? Where? How much? What sort of eruption? No one can guess.
