The Next Great Cascadia Earthquake - How did we get here?
Our understanding of plate tectonics is only about 60 years old, and we are still low on the Earth's learning curve. Cascadia earthquakes helped usher in a new hypothesis of everything, but then was forgotten for many years. More recently, our understanding of Cascadia earthquakes suddenly went from unknown, to a potential generator of M9 earthquakes in just a few short years. How did this happen, and what does the future hold?
