Strange Mysterious Sound Reported In San Diego

The mysterious sensation was described by some people as sounding like a door slamming whilst other people stated it was strong adequate to rattle windows.

A verify of the U.S. Geological Survey website showed no earthquake activity.

NBC 7 San Diego’s Dagmar Midcap was in Del Mar at the time and described it as a “Sonic ‘rumble’” She tweeted, “according to my contacts at USGS, not seismic but rather sonic.”

Two months ago, when San Diegans heard a comparable sound, there was evidence of chaff on weather radar. Chaff is a material at times emitted during military workout routines.

On Friday, nevertheless, Tina Stall with the National Weather Service mentioned there was no visible chaff in the location at the time the noise was reported.

The mysterious sound had both residents and specialists scratching their heads. Scripps Institution of Oceanography scientist Kristoffer Walker stated he felt it too, and looked into microphones recorded from MCAS Miramar.
