Happy #FieldworkFriday! Our station GORGE is now powered up! After upgrading from 2 to 4 solar panels, & adding a wind generator, we had to adjust for all the extra power. The recent “false-spring” weather here in the PNW has this station looking GORGEous & getting lots of juice!

Today marks the anniversary of the 1700 Magnitude 9 Cascadia Subduction Zone earthquake, reminding us to be prepared for strong shaking in the PNW. URMs are particularly vulnerable, but retrofitting can mitigate the risk. #FixTheBricks www.youtube.com/watch?v=C5wa...
Fix The Bricks! Building Safety is Earthquake Safety
Retrofitting buildings in preparation for our region’s next big earthquake will save lives!
🧱 Retrofitting URMs is not just about preparing for the next earthquake; it's also about supporting…
