"#Coronae" are defined by a (partial) quasi-circular ring of closely spaced concentric fractures. They are hugely abundant on #Venus' surface and considered key for Venus' tectonic and volcanic history ⚒️🌋

It was such a pleasure to attend #LPSC25 last week and present my latest #Venus #science work, some originating from my time at NASA Jet Propulsion Laboratory; @caltechseismo.bsky.social. These presented studies will likely soon result in some exciting publications (stay tuned...)!

⚒️ There are many reasons for wishing to be at #EGU24 in Vienna last week, but the biggest must be the award ceremony for my mentor Taras Gerya @eth-erdw.bsky.social
(ETH Zurich 🧪) , who was awarded the August Love Medal from the Geodynamics Division @eurogeosciences.bsky.social 🔭 Congrats Taras!

3D tectono-magmatic models of plume-margin interactions on Venus reveal
- several tectonic evolution scenarios, highly dependent on lateral variation in lithosphere strength
- longer magmatic lifetimes for asymmetric coronae (vs symmetric)
