I am a climate scientist, focused on paleoclimate, sea level change and the evolution of Quaternary glaciations.
I reconstruct ice sheets using glacial isostatic adjustment and ice sheet modelling. In Japan but have been all over the place. 🇨🇦🇯🇵🇦🇺🇩🇪🇸🇪

Hello Bluesky folks! I am interested in meeting people working on climate, sea level and ice sheets, especially with reference to the past. Please visit my website for a larger bio! raisedbeaches.net/about/

There was a moderate earthquake a few minutes ago near Mt. Aso in Kumamoto. I was on a bus so I did not feel it. Based on the moment tensor and depth, it is probably on the same fault that ruptured in 2016. earthquake.usgs.gov/earthquakes/...
