2. This morning’s M6.3 event near Wells.
For 2006 and half of 2008, NSF-funded USArray stations- blue triangles- help us monitor E. Nevada. They move east in a few months!
It would cost $30k to retain a station. How do we keep the 40 USArray stations that are the only way to monitor quakes like this?
