Great, something else to worry about. According to Dr. Claire Asher, skyquakes are happening more frequently, and scientists don’t know why. Of course, it begs the question “What is a skyquake,” and Dr. Asher has the answer. “If you’ve ever heard a loud, distant booming noise with no obvious explanation like a thunderstorm or a car backfiring, then you might have experienced a skyquake. She says they could be caused by solar flares, earthquakes, offshore tsunamis, collapsing underwater cafes or avalanches, or even meteors. And yes, that’s as much as experts have been able to narrow it down. Of course, some people think it’s aliens, but at this point it’s as good a guess as any.
