Interactions between Magmatism, Tectonics, and Faulting in Rifts, Arcs, Ridges, Calderas, and Volcanic Fields
Session ID#: 72237
Session Description:
Interactions between magmatism, tectonics, and faulting occur at different temporal and spatial scales, as they are observed from individual volcanoes to plate boundaries, during single eruptive events or over centuries. However, our current understanding is still limited due to a lack of integrated approaches. Field, geodetic, and modeling studies suggest that earthquakes can trigger volcanic eruptions and intrusions through static and dynamic stress transfer. Conversely, magmatic activity can generate earthquakes via stress changes in surrounding country rock. In rifting events, magmatic fluids can release tectonic stresses and also be influenced by pre-existing fracture zones. Finally, the combined effects of magmatic, gravitational, and tectonic stresses can trigger caldera and volcano flank collapse. We strongly encourage multidisciplinary studies integrating geodesy, structural geology, volcanology, geochemistry, seismology, stress analysis, and/or modeling (numerical and analogical) to decipher relationships between magmatic, tectonic, and faulting processes at different temporal and spatial scales.
