the effects of earthquakes are amplified, meaning cities like Eugene, Salem and Portland might see even greater impacts.

The new bridge will be earthquake-ready, so crews are digging a 10-foot-wide, 125-foot-deep hole to see how concrete supports react during a simulated seismic event.

They’ll also build the system they’ll use to fake a Cascadia Subduction Zone earthquake. "So in the steel reinforcement cage, we have what's called load cells and those are basically two-foot ...
