They could pick up these units with a Boxing Day sale. Seriously, the big quakes are due in a month, and it might be the only time to get a GPS signal for eastern earthquakes. As we know, they put these units all over New Madrid and got nothing. That parrot is dead!
My Christmas wish is for a big array of GPS all over Oklahoma. Then it would show what the local 'stress-quakes' are showing. We would expect a slow rise in the city (on the thrust), and relative motion on the shear wings. I am patient, and I'm sure we'll get the gps eventually, but it'll be too late.
Update: another isolated stress-quake. Things are heating up!
Update2: M3.1 isolated earthquake.
