"I give up"

Don, I do not believe you are a quitter.

It is a strange feeling to know exactly what your (plural) misunderstanding is, but at a loss to put into words.

Don, Chris has answered a question that you did not pose, but Cathryn posed it through her misinterpretation of your post.

It is a good question. And anyway, the same phenomenon that Chris mentioned is happening here in Japan. One place is just a few kilometers from my home. Recent activity has gone up, with several@>3M quakes in the last week. That is the Wakayama City area.
