The annual @SCEC meeting in Palm Springs has begun this week, which means...
It's time for an #AlwaysAWindowSeat tour of the plate boundary thanks to my NorCal-SoCal flight. A thematic thread, complete with faults, infrastructure, trains, and clouds 😍: Flight started at one of the [four] last places you see the San Andreas Fault on land.
Pop quiz, geo-Google-Earthers: what is the closest major airport in the world to a major fault line? Show your work
