  abstract = {{V}iscosity is a fundamental physical property that controls lava flow dynamics, runout distance, and velocity, which are critical factors in assessing and mitigating risks associated with effusive eruptions. {N}atural lava viscosity is driven by a dynamic interplay among melt, crystals, and bubbles in response to the emplacement conditions. {T}hese conditions are challenging to replicate in laboratory experiments, yet this remains the most common method for quantifying lava rheology. {F}ew in situ viscosity measurements exist, but none of those constrains the spatial evolution of viscosity along an entire active lava flow field. {H}ere, we present the first real-time, in situ viscosity map of active lava as measured in the field at {L}itli-{H}rútur, {I}celand. {W}e precisely measured a lava viscosity increase of over two orders of magnitude, associated with a temperature decrease, crystallinity increase, and vesicularity decrease from near-vent to distal locations, crossing the p},
