I don't quite know what happened with seismon. I updated the USGS client yesterday and restarted that code, but I didn't make any changes to the seismon code. I've restarted the seismon_run_info code that we are using and that seems to have fixed it. Maybe the seismon code crashed when I added geopy yesterday?
