Sylmar Quake 1971 (6.6)
Whittier Narrows Quake 1987 (5.9)
Big Bear Quake 1992 (6.4)
Northridge Quake 1994 (6.7)

The Northridge Quake was really destructive because it triggered off some faults that hadn't had any activity in many, many decades. Some of the faults were unknown to seismologists until the quake hit. One failut that broke loose was only about a half mile from my residence, so we felt not only the shaking from the main quake but, also, the "sub-quake" caused by the local fault giving way. Definitely an 'E' ticket ride..

Back when they still did underground testing, a particularly large test was expolded that caused tremors felt all the was to Las Vegas. News reports at the time said when the shaking hit the casinos, gamblers paused for about a split second and then carried on with their games, totally ignoring
swinging light fixtures overhead...

Good post with good stats Thx vienna
