Which ones do you remember the most? I was there in 1992 for the big three.
But to answer your question, the most violent one was a 5.8 just about under Eureka and very shallow. It dumped me out of bed about 6AM. It was a few years after the 92 swarm. My wife and daughter were out walking and they thought the world was ending because of all the transformers and wires arching.
