Relating Dike Geometry and Injection Rate in Analogue Flux-Driven Experiments

Dikes feed most eruptions, so understanding their mechanism of propagation is fundamental for volcanic hazard assessment. The variation in geometry a propagating dike as function the injection rate remains poorly studied. Here we use experiments injecting water into gelatin to investigate thickness, width and length flux-driven connected its source time intruded volume. Results show that thickness vertically dikes proportional constant long latter constant. Neither buoyancy nor injected volume influence thickness. along-strike is, however, These results, consistent with inferred behavior several observed during emplacement, open new opportunities better understand how propagate also forecast emplacing may once geometric features are detected real-time through monitoring data.
