[Frontier Letter] Forecasting the fate of vertically propagating dikes from geodetic data
This study investigates the cause of dike arrests beneath active volcanoes by reconciling geodetic measurements with theoretical and experimental insights. Four causes of dike arrests are considered: (1) solidification, (2) insufficient volume, (3) negative buoyancy, and (4) stress perturbation near the dike tip. Then, this study discusses the cause of dike arrests associated with the 1997 and 1998 seismic swarm off the Izu Peninsula, Japan, and the 2015 failed eruption of Sakurajima volcano, Japan, as an example. This study suggests that the Izu Peninsula cases are caused by insufficient volume of the dike, the loss of buoyancy, or both. The Sakurajima case is most likely due to insufficient volume.
