lutra Oct 24, 2018 01:12 PM Origin of Loud Sounds At Goleta Beach? I also heard loud sounds in the early morning (after midnight) hours of 10/18/18 and would like to know what they were. I'm wondering if these were the same sounds that the OP heard. We're near Magnolia shopping center, and they sounded like loud thumps that were occurring every 15-30 minutes for many hours non-stop. If they sounded like explosions near Goleta beach, I can imagine that the sound, traveling all the way over here, would be more muted.
