I was listening to “All Things Considered” from NPR on the way back from Hamilton just then. I heard this piece…very interesting.

Here is some information:

And the actual paper:
https://www.science.org/doi/10.1126/sciadv.abm4310
> Magma rheology and volatile contents exert primary and highly nonlinear controls on volcanic activity. Subtle changes in these magma properties can modulate eruption style and hazards, making in situ inference of their temporal evolution vital for volcano monitoring. Here, we study thousands of impulsive magma oscillations within the shallow conduit and lava lake of Kīlauea Volcano, Hawai‘i, USA, over the 2008–2018 summit eruptive sequence, encoded by “very-long-period” seismic events and ground deformation. Inversion of these data with a petrologically informed model of magma dynamics reveals significant variation in temperature and highly disequilibrium volatile contents over days to years
> a framework for inferring subsurface magma dynamics associated with prolonged eruptions in near real time
I wonder what they mean by “near real time”.
Interesting “Fig. 1. Kīlauea magma dynamics model”. I’ve seen something very similar used in aerodynamics sound modelling. It hadn’t occurred to me that it could also be applied to magma.
