Is the eruption pau.. or maybe just taking a siesta?
As it is, since late yesterday morning, instrumentally, Kilauea's summit (as measured with a tilt meter) started a relatively steep deflation, which since it began has amounted to a mere three microradian loss (so far?), but still seems to have marked the cessation off lava production.. maybe the end of the eruption? Or, maybe it's just a pause? Either way, there does not appear to be an eruption in Halemaumau at this time.
Remember when we had pauses? Like during the Kalapana era we'd have these deflation events which were like bubbles in the system.. Or at least I, at the time, imagined them as such because as the summit would deflate slightly a few hours later the eruption down on the rift would pause, and the lava flow in Kalapana would stop, and then the next day the whole thing would start up again. Eventually attention turned to Deflation Inflation events, often called DI events, which have a similar deformation signal, and are believed to be associated with magma transfer between the main and the shallower magma chambers under the summit. We've been having a series of tilt signals like those recently..
As of this writing there's no activity apparent, when the clouds clear, on the summit cameras.. https://www.usgs.gov/volcanoes/kilauea/summit-webcams
And the summit tilt is more or less flat.. https://www.usgs.gov/volcanoes/kilauea/deformation-data
But what the future will bring...? Well, of course it'll bring another eruption.. but when? Tonight? Tomorrow? Next week.. year..
