There was an earthquake swarm in March of 1978 that was perhaps larger than the current swarm. For many days (over a week, as I recall) it went on, and the staff at the OFVC felt dozens of them. Two very good things happened from that swarm. Daisy became regular for the first time in years, and Splendid became much more common - 1978 was a very good Splendid year. I believe the March 78 swarm was centered on the Madison Plateau. If someone has records of this I'd like to know. I do have Rick's annual report somewhere for that year, and will see what he wrote about it. BTW, there's a lot of pretty wild stuff out on the internet about the swarm.

I have been going into the Park for fifty plus years and this is a first for me. Norris Geyser Basin has given us a few clusters of earthquake activity, but I believe this is the biggest and best in my life time. A friend of mine plotted all the recent earthquakes by longitude and latitude on Google Earth. He sent me his link and I took some computer snapshots. I have attached two of them so everyone can enjoy them. Hope you like them.... Gary Henderson Meridian, Idaho -------------- next part -------------- An HTML attachment was scrubbed...
