Really was not expecting to hear the name #Shimanto (AKA #KochiPrefecture) in a lecture about the #Cascadia / #JuanDeFuca fault.
The Shimanto Mountains were mentioned as an analog of our own #OlympicMountains - both are non-volcanic, near a #megathrust #SubductionZone (#NankaiTrough for Japan: major #earthquake every 100-200 years), and contain remnants of paleomegathrust (new fave word) fault lines thanks to historic and ongoing subduction.
As terrifying as it can be, I love #geology so much.
