kengrEarlier this week new info on faults around Mt. Hood came out.
The news item wasn't specific, but from the description, it sounds like they used lidar to map the surface without the trees getting in the way.
They uncovered several previously unknown faults as well as evidence of major quakes 6000 & 3000 years ago.
If these faults let go, Portland would get a 7.2 quake.
So Ysabet's "The Big One" quake(s) on Terramagne are likely to trip those faults. Which would add more destruction to Portland and a lot of other places in NW Oregon.
