Structure of Volatile Conduits beneath Gorely Volcano (Kamchatka) Revealed by Local Earthquake Tomography

A seismic tomography model of Gorely Volcano, Kamchatka, reveals the structure of volatile conduits beneath the volcano. The study identified a 2.5 km wide and 1.5 km thick magma reservoir with high Vp/Vs ratios (up to 2) located 2.5 km below the surface, indicating a region with high melt or volatile content. This reservoir coincides with intense seismicity, suggesting it marks the degassing level. Below this reservoir, another columnar anomaly was observed, interpreted as a conduit supplying magma and fluids from deeper sources. The study used data from 333 local earthquake events recorded by a temporary seismic network over one year, providing the first tomographic model of Gorely Volcano.
