Pre-eruptive magma conditions and tectonic interactions in a geothermally active volcanic system
Abstract:
In modern volcanology, significant efforts are dedicated to understanding the subsurface processes that drive surface monitoring signals observed at active volcanoes. Accessing the depths where these processes occur is challenging; therefore, insights into magma storage and ascent conditions often come from studying eruptive products. The Main Ethiopian Rift offers an ideal location to study these processes, characterised by regularly arranged active silicic volcanoes and small fault-controlled eruptive centres. These silicic volcanoes have produced hundreds of cubic kilometers of highly evolved magmas, many of which host large calderas and edifices formed in the post-caldera stage. In my talk, I will focus on one of these volcanic complexes, Bora-Baricha-Tullu Moye, and discuss pre-eruptive magma conditions and tectonic interactions.
