Re: Hot On The Trail In Earthquake Country

Hi All. As usual Petra takes me, or has me take her all over the place. If it’s not one place its another. I have to admit it’s interesting to see where I’m going next.

So you say climbing a tree is easy. So is falling out of them and breaking your neck you knuckle head.

This was the first time I had been to The Earthquake Trail in Olema, Ca. so it was a new experience for me. For those who haven’t been there I would recommend going. I know most of you have seen pictures of the fence, but its something all together different to see it live. It sort of leaves you with a cold feeling of just what kind of power a quake of that magnitude must be to move the surface of the earth 12 feet in the time it takes you to blink an eye. The way the tree is laying the next large quake will rip the top half away from the bottom much the same way it did the fence.

Petra feels very strongly about this quake. She told me more then once we were going to have a quake. She puts it in a time frame of 90 days. That gives me plenty of time to study the data, but then maybe not. There is a lot of creep in the Bay Area that can’t be accounted for. The last time this happened was at the SJB site. There was an increase in creep, which lasted for ten weeks before the 1984 quake at Morgan Hill. There was also an increase in the Bay Area creep before the Yountville quake. For a very short period it returned to normal, but what is there now is not normal. It could be we don’t have a maximum of 90 days. Take Care…Don in creepy town.
