In the event of earthquakes, I am planning to get some use from the 6' long pry bars I have acquired, pointed on one end and a chisel on the other. I have not used these in building demo or in extrication, but I did acquire experience with them in reconstructing some historic dry stone masonry. I was very impressed at what a nice long pry bar could accomplish in moving heavy stones. I will be happy if I never have to post about their utility in the aftermath of an earthquake, but you can never tell.

I also have an assortment of smaller tools; a standard crowbar is right at bedside.

Lately we have experienced several very small quakes (2.5-2.9) locally (San Nicholas Island, Westlake Village, Carpenteria). I sure hope these aren't precursors...
