Kilauea Eruption 12/23/24

[TomK]

Well maybe you'll listen to USGS for some answers to your questions TomK. The "blips" or "diurnal noise" are real readings from the instrument caused by the thermal expansion of the surrounding rock.

Sigh...

Yes, I know that. I asked whether the instruments were subject to thermal expansion and contraction and, if so, what corrections were made. There's no point measuring a very small effect using an instrument subject to the same effect without correction. Given that the instruments are on or close to the surface, they experience the same conditions as the rock or soil surface layer.
