Well, with all the other things going on phase 54 of the ongoing series of eruptions at Halemaumau passed, in these hallow halls of discourse, without notice. But hey, there's been a lot going on.. right?
And still, in the background of it all there's a bit one can say.. the events get shorter, the fountain heights not as high, but overall this event has been one of many of a similar profile, when seen as compared here with all the rest on the summit tilt record..

Where ever since the change 11-12 episodes ago from the higher volume, longer lived events that over time showed the summit (in the area of the tilt meter) losing a bit of height over time, which changed to shorter events with smaller fountains but an accumulating summit height with time, and still, overall, it's been remarkably steady hereabout. We have eruptions, they happen like clockwork, what's to say?
And, as usual, with the end of phase 54 on Tuesday evening BIVN posted an update from HVO which in part said:
An abrupt switch from summit deflation to inflation at the end of the episode, as well as the resumption of low frequency tremor bursts, indicate that another episode is likely in the coming weeks, scientists say.
Which, as anyone who's read these over time has gotten used to, this is a boiler plate the eruption ended inflation resumed statement. Although, now that a little bit of time has passed the sequence that has followed is anything but boiler plate. Here's the tilt for the last week now..

Where it is obvious that after a few hours of the noted inflation after the eruption ended the mountain switched to deflation and is continuing to do so. And, by all accounts, this is the first time since the onset of this eruption series that this has happened.
Note that the plots here are dynamic. They are direct feeds from HVO, and as such will change over time, and the second, one week, plot will only show this change for the next 5 days (after this posting). Although, these both are from the HVO deformation page which can be seen here for a continuous look at the volcano's internal workings through their array of deformation instrumentation.
