"You can’t hear it, but the Earth is constantly humming. And some parts of the world sing louder than others.

After discovering the mysterious low-frequency buzz in 1998, scientists figured out that the Earth’s hum is caused not by earthquakes or atmospheric turbulence, but by ocean waves colliding with the seafloor......."


Not surprisingly, it seems to be coming from North American Pacific Coast.

The Farallones?

I think that the local inhabitants would put up a huge SQUAWK!

Perhaps those who complain of hearing voices have been correct all along.

Surprised that we earthlings haven't had complaints about the constant humming. On the other hand, maybe that's what attracts UFO's-- trying to turn off that incessant noise coming from earth.

TWIMC:
The California Academy of Sciences has recently placed a webcam on Southeast Farallon Island (currently down for maintenance):

FYI, The islands are near to the edge of the continental shelf and were, therefore, part of the mainland before the notorious hot-wind-from-Nevada melted the ice sheet at the end of the last glacial period.

I hadn’t really paid attention to it before, but if you go to the satellite view in Google Maps you will see that they superimpose their visual images on a bathymetric representation of the world’s oceans which, among the other features, nicely shows the extent of the continental shelves:
