A new paper by IPGP and OVPF researchers A. Lavayssière and L. Retailleau:

Capturing #Mayotte’s deep #magmatic plumbing system and its spatiotemporal evolution with #volcano-#tectonic #seismicity

With a beautiful evaluation of #earthquake location uncertainties

Sketches showing the deep magmatic plumbing system offshore the island of Mayotte as deduced from the analysis of seismicity. Two cross-section across seismicity clusters show events colour-coded by time and sized by magnitudes before and after mid-March 2020. The majority of seismic events are quite deep, between 25km and 45km, and related to three magmatic chambers in the lithosphere.
