Anons. Check out the national data buoy center (Google it!)
Three buoys in event mode off PAC NW and one in event mode off NE USA.
Lots of things can send these buoys into event mode (weather, seismic events, localized disturbances).
We are supposed to watch the water. These are curious events off both coasts.
Won’t speculate further without sauce, but the water bears watching, folks.
