TRANSCRIPT:

The Story of the Pacific Northwest

Never before in human history have so many people known so much about a risk so large that we’ve never experienced together. But I’ve experienced it, right alongside my wife, which is why this idea is so personal and important to me. I’m going to tell our story at the very end. To begin, I want to tell you a new story of the Pacific Northwest.

The story of the Pacific Northwest begins 3,000 miles away. To be exact, 3,000 miles beneath your feet. Because up from that spot in the core, there’s a massive column of magma, which is rising to two massive plates out at the sea. And those two plates are spreading in opposite directions, but their journey is the same.

Right now, the Juan de Fuca plate is sliding right underneath your feet, in the exact same way that the Pacific plate is sliding beneath Japan. Now, the story doesn’t end there, because that plate, as it dives, the friction and the depth causes it to melt. It becomes a pool of magma. It rises to the surface and creates landscape.

This process created Mount Fuji. This process created Mount Hood. This process created Mount Rainier. And unsurprisingly, this process created Mount St. Helens. This process is called subduction. And subduction is about a lot more than beautiful landscape and occasional volcanic eruptions. It’s also about risk.

The Risk of Subduction

See, right now you’re standing on North America, and North America actually goes all the way out to the ocean, where it is locked with the Juan de Fuca plate.
