Ken and Betty Smith live in California and have holidayed in Shannonbridge for the past few years. Being in California they take a healthy interest in earthqukes and Tsunami affairs. They sent the following links that they check out for rumbles -

Hello Der and Happy New Year. I missed your news over the holidays. I hope everyone is healthy. I notice your interest in the word tsunami, but then I have always noticed your keen intellectual interest in many things. We who live with earthquakes are familiar with such things. We had one here in California in 1984 but due to the warning system very few were killed. It was generated by a 9.2 earthquake in Alaska. Here in Santa Barbara we had tidal surges that caused the tides to rise and fall 6 times in a 5 hour period. Believe it or not when the alert sounded here in Santa Barbara many surfers grabbed their boards and headed for the beach. Fortunately for them the major wave hit north of here (Crescent City) where several people died despite being told to take to high ground. You might check out the following website.

You can click on the map to get details of a particular earthquake. Since there have been so many aftershocks the main earthquake is covered. It had detailed information as to what caused the tsunami. The one below gives all of the signifigant quakes of 2004 and if you read through them there are several tsunamis, but not of the same magnitude as the devestating tragedy of last week.

Earthquakes are posted on the website minutes after they occur and I always head for the computer and pull up the following when we shake, which is quite frequently.

If you pull it up you will see California is shaking as I write. We only feel the local ones here or if a 5 or greater occurs within a couple of hundred miles or so..
Did you get the picture of George I sent? That's your lot, Ken
