Tremors are quite common and occasionally, they get over-ambitious and qualify as quakes. The little village of Comrie, about 15 miles west of Perth where I used to live, was right on the Highland Fault and the locals got their crockery rattled every day or two. That is a good situation, because it is slipping all the time, not sticking and building up to a huge double whammy.
I had my biggest scare ever in 1987. Daughter and I were visiting the Scottish family and we were out for a drive in a favourite area. Caught up to a semi-trailer, which was doing well but just slow enough to be a nuisance. I remembered the road from before I emigrated in 1968, so I just sat back and waited for an overtaking opportunity which I knew would appear soon.. It did, it was clear, so I went for it. Halfway along this big curtain-sided truck there was a crash and a roar and something flashed in front of me about 50' AGL. One of those situations where you fly the plane - we got past, the truck had not fallen on me, the car was still fully functional, and at this point young bro in the back seat informed me that this was one of the terrain-following training areas for RAF Jaguars
They didn't have them in my day.
