TomK - Sigh...
Sigh indeed - if you read the USGS link provided (or this paper) you might see why given the installation conditions the instrument itself is unlikely to be heated in an uneven way and therefore the cause of the diurnal pattern. There is more discussion there, and in the Mt Edna paper, of other subtle causes of noise (including even the tilt detected due to rain filling the small air gaps or pores in the surrounding rock!) that are accounted for by those involved with the work.
MyManao - In a closed hydraulic system, with a fluid that itself is minimally compressible... If that same closed break system were to get a hole in it it would then become an open system... Which is Kilauea...?
So you're saying it's like a pie crust growing more flaky as it heats... ;) More seriously, it would seem to me like other volcanoes under observation may offer some comparisons? Are there volcanoes where the diurnal heating isn't as great and therefore this possible bump in magma accumulation isn't as pronounced or not present at all? Alaska volcanoes comparing between summer and winter where the difference in thermal gain from solar exposure would be the most pronounced? Just thinking that in trying to sus out a correlation/causation issue that other systems might help to isolate the effect.
ETA: Looks like the deflation (and listing to a side?) really kicked off at around 6a kalianna. Someone more knowledgeable might have insight as to the delay timing between the eruptions & deflation detections.

Regardless, the idea of earth tides was eye opening enough for me to recognize how little I know about the world. Going to go surf the ground swell as the sun passes overhead. A hui hou!
