Rocking! Ripping! Jolting! Shaking! This is what happens when tectonic plates collide and separate. The Cascadia Subduction Zone, a fault that runs from Northern California to Vancouver Island, is a big crack in the Earth’s crust that is part of the infamous Pacific Ring of Fire. Bring the family to make your own “earthquake wave box” and learn about plate tectonics, geologic history, and seismic risk in the Pacific Northwest. Presentation begins at 2:00 p.m. and is best for ages 10 and up. Related activities in the classroom all day.
