I am not convinced the tremor signal is clear, free from atmospheric influence.. and as such that sudden drop earlier this morning could be the wind speed dropping below a certain threshold as much as it might be a marked decrease in actual tremor..
Curious as to what led to this addendum - what thresholds might be involved and why this confounding factor is/isn't also gathered at the data source and factored in. Any explanation or pointers to readings on this are appreciated!
It’s purely anecdotal, my own observations, experience.
Back in the day.. ie before the eruption started and the signal, the seismic trace, wasn’t overwhelmed with tremor, I noticing flurries, bands of increased what looked like sloppy tremor, that weren’t otherwise accounted for.. ie just seismicity without other data streams acting up as well. At the same time I was watching the IFA’s weather page to get a feel for weather conditions.. temp, wind direction/speed, humidity.. and I noticed those bands of increased seismic noise coincided with periods of high winds as recorded on MK, and assumed were happening at ML as well.
Whereas the tilt.. have you appreciated how much the summit has re-inflated? What’s striking to me is how the rate of re-inflation is so similar to, and, at a casual glance looks to mirror the same rate of deflation during the steady state last half of the eruption’s deflation..
The tilt for the last month.. ie up to and including the entire eruption and the now steady rebound..
And yeah Kilauea’s behavior.. chicken skin.. like wow.. But interestingly there’s no clear change instrumentally as it is with ML.
