YouTube is a great tool if used correctly, but you can find some utter nonsense! I usually try to avoid posting on this kind of thing, however, this video actually confused me greatly and annoyed me as well. Please don't watch it all, it is nine minutes long, watch just a little and you will get the jist. The author states the following in her description:
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.
To cut a long video very short. The author assumes that these lines flashing up on Google Maps/Earth (whenever the author moves the map) are somehow linked to recent earthquakes and/or a sink-hole because a line may randomly cross a recent earthquake event. They are obviously not. I am no graphics expert, but it seems quite obvious that they are the result of loading or redrawing of the map as it is moved. At which point do we jump to seismic signals, infrasound or Haarp?! In science the principle of parsimony is often referred to: if there are many theories the simplest should be preferred. This is definitely the case here.
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.
