Strange Pulses and Creepy Sounds Detected

[gordi]

.....This has me very curious.  What's going on?

Anyone have any ideas?

Hi Mystic,

The Plymouth one just sounds like the wind to me.

I have no idea what the weird Pulse is on the seismographs.
Did you confirm that it was definitely travelling East to West across the US? (My US geography isn't great)
What did the narrator mean about a Ship off the East coast just now?? Did I hear him correctly?
