How strong of an earthquake does it take to leave a mark on the geological record? We can tell when there were major earthquakes in history by looking at the shifts in layers of rock and soil - but earthquakes happen all the time, mostly small. So how strong must an earthquake be before it leaves noticeable geological evidence?
