flashing lines may or may not be seismic monitoring signals, haarp, infrasound, or something else, but they appear to connect to earthquakes on this static google map. Probably a plug in designed to pick up signals or to monitor weather, i.e., eqs, seismic movements.. The google portion of this report is not verified or confirmed as factual, this is only a investigation and observation.
The only factual part of this report is that there was a 3.2 earthquake in the Yellowstone area (not really that unusual by the way). Please please please tell me this was an early April Fools joke, unfortunately I don't think it was.
