Title: Earthquakes, Magmatism, and Burkas: Seismic Investigations of the Red Sea and Arabian Peninsula
Abstract: The Red Sea is an archetype extensional environment, marking a transition from continental rifting to seafloor spreading. Many questions exist on how the Red Sea initiated and has evolved through time, how the subsurface (crustal, lithospheric, and mantle) structure beneath the Arabian Peninsula relates to the rifting, and how the deeper Arabian-Red Sea structure influences near-surface magmatism and earthquakes. Over the past 10+ years, I have conducted a variety of seismic investigations focused on these questions. This presentation will highlight several early studies as well as a more recent investigation aimed at understanding seismic swarms in the Harrat Lunayyir lava field. Some of the interesting cultural aspects associated with working in Saudi Arabia will also be shared.
