I have earthquake maps of the west coast....Over 1000 quakes in the past...When on vacation I saw a map of Arkansas and there are a lot of vaults lines in that state...You have to remember that there may not be any history in your area but they have been happening for millions of year..Art
As a young man while wondering around the mountains hunting and fishing I saw a lot of Geological features that looked out of place....Years later I was in a book store looking at a Geological book and there were photo’s of these feature....Yes things like dikes and quake vaults....So I started reading about them...There is so much to learn..Art
