Scientific response to the 2021–2022 seismic swarm in the Monts Dore volcanic province (France): structural insights from punctual surveys (1/2)
Long-dormant volcanic provinces remain excellent proxies in studying active edifices. The Monts Dore volcanic province (French Massif Central) has been recently the site of a unique seismic episode. Geophysical surveys were conducted at different horizontal and vertical spatial scales. Magnetic anomalies highlight mechanical heterogeneities consistent with the regional tectonic context. Low-conductive structures imaged suggest the presence of fluid rising along main paths at various depths. Although we cannot strictly exclude a purely tectonic explanation, our data seem to support the origin of seismicity as being linked to the injection of fluids at depth controlled by internal structural constraints.
