The sound was recorded by audio engineer Brian Sullivan.
â€œThe first night, no luck. But, Sullivan said he captured a boom from this past Saturday, one minute before 4 a.m. Itâ€™s short, but it sounds like a boom,â€ reports 790 KABC.
One of the comments that keeps cropping up with regard to the Clintonville booms is that the official explanation of earthquakes is inconsistent with what residents are experiencing. You donâ€™t hear an earthquake so much as feel it, whereas the booms are being both felt and heard.
The noise recorded by Sullivan sounds more like a deep underground explosion than a seismic event.
