Wed 15 May 14:00: The Turkana Rift Arrays Investigating Lithospheric Structure (TRAILS) Experiment
The Turkana Depression is a broad, topographically-subdued, region between the elevated Ethiopian and East African Plateaus. The Depression is unique in East Africa for being host to a NW-SE-trending failed Mesozoic (Anza) rift system through which the near-orthogonal, N-S-trending East African Rift subsequently developed. Whether the Depression’s low-lying nature is a result of a significantly thinned crust instigated by its multiple rifting phases, or instead due to a lack of dynamic mantle support is debated. Also poorly understood is the extent to which Cenozoic rifting and magmatism have developed across the Depression during the linkage of other comparatively narrow East African Rift zones to the north and south. Utilising data from the 2019-2021 Turkana Rift Arrays Investigating Lithospheric Structure project and surrounding networks, receiver function analysis and its joint inversion with surface-waves, are used to probe Moho architecture and the lithosphere-asthenosphere system.

Thu 09 May 11:30: Engineering solutions for heart valve disease using computational modelling and simulation
Transcatheter valve replacement is a revolutionary, minimally invasive alternative to surgery for patients with heart valve disease. With over 1.5 million procedures performed worldwide and expectations of a sharp increase in the coming years, there is growing concerns about the rise in adverse events such as coronary obstruction and valve thrombosis. It is anticipated that the interaction between the implanted transcatheter heart valve with patient-specific anatomy may give rise to unfavourable hemodynamics, contributing to these adverse events. In this seminar, we will explore the role of computational modelling and simulation in improving our mechanistic understanding of these events, and as a tool to assist clinicians in patient selection and pre-procedural planning, ultimately improving patient outcomes.

Wed 05 Jun 17:30: Extreme glacial implies discontinuity of early human occupation of Europe Building doors are card operated, so latecomers may not be able to access the venue.
The oldest known hominin remains in Europe [ca. 1.5 to 1.1 million years ago (Ma)] have been recovered from Iberia, where paleoenvironmental reconstructions have indicated warm and wet interglacials and mild glacials, supporting the view that once established, hominin populations persisted continuously. We report analyses of marine and terrestrial proxies from a deep-sea core on the Portugese margin that show the presence of pronounced millennial-scale climate variability during a glacial period ca. 1.154 to 1.123 Ma, culminating in a terminal stadial cooling comparable to the most extreme events of the last 400,000 years. Climate envelope–model simulations reveal a drastic decrease in early hominin habitat suitability around the Mediterranean during the terminal stadial. We suggest that these extreme conditions led to the depopulation of Europe, perhaps lasting for several successive glacial-interglacial cycles.
Building doors are card operated, so latecomers may not be able to access the venue.

Wed 08 May 14:00: Searching for habitability on Venus and exoplanets
Venus today presents a type example of how habitability can fail to persist on a planet: rocky and to a first order overwhelmingly Earth-like, but with a climate profoundly hostile to life’s complex molecular machinery. But, was it always like this and will we know a Venus from an Earth when we see one elsewhere in the galaxy? This talk investigates what evidence there may be to constrain Venus’s past climate state, and relates this to the frontier of our search for habitable conditions on exoplanets.

Wed 01 May 14:00: New Insights from the Collaboratory for the Study of Earthquake Predictability (CSEP)
As seismology enters the era of statistical aftershock forecasting and continuous real-time seismic hazard estimation, the community needs independent model evaluation methodology to provide the best available science and to understand its current limitations. CSEP is a global community with a mission to improve earthquake forecasting by comparative model testing in a truly prospective manner (i.e., against data not yet available during model development). In this talk, I will provide an overview of new insights into earthquake predictability gained by CSEP experiments around the globe and over nearly two decades. I will illustrate how these insights are informing national seismic hazard models and real-time forecasting.
