Surface Crevasse Evolution Observed Using Matched Field Processing and Source Relocation at Hansbreen, Svalbard
arXiv:2606.10992 · kill-test 2 OPEN (no contradiction edges)
- claim We propose a two-step workflow integrating Matched Field Processing and discrete arrival times relocation to map glacial seismic activity at meter-scale resolution under limited instrumentation. Applying this to surface icequakes at Hansbreen allows estimation of crevasse propagation rates and diffusion coefficients of 0.47 to 0.55 m²/s. We interpret the crevassing as sustained subcritical crack p
- falsifier Independent measurements of the same crevasse opening episodes, for example via repeated drone surveys or time-lapse cameras over the study period, that produce opening rates or diffusion values outside the 0.47-0.55 m²/s range.
- machinery Two-step workflow of matched field processing followed by arrival-time relocation for meter-scale icequake source localization under sparse array constraints
- premise The relocation step after matched field processing truly removes systematic location errors and delivers unbiased meter-scale accuracy with the available sparse instruments.
