Hi Bill. Welcome to the board. Always glad to see some new persons.

I had thought about the bulge, but wasn’t sure where it would fit into the scheme of things. I suppose that the cause could be related, but would like to see more data before making any determination on it. It would be interesting to learn if it’s still continuing at this time. It would also be interesting to learn if it took 10 years to get this large, or if it became this large in a couple of years. There is a seismograph in the area now and to the best of my knowledge there have been one or two very small quakes recorded.

Oregon doesn’t have many quakes, but then you only need one big one to make up for all the ones you didn’t have. Take Care…Don in creepy town
