What is the Q of the Earth? It might be on one of your web pages, but I don't remember seeing it. Google found a few mentions, but I didn't find a number. I did find an interesting list of damping mechanisms in a geology book. Geology-nuts are as nutty as time-nuts. Many were discussing damping of seismic waves rather than rotation. I've seen mention that the rotation rate of the Earth changed by a few microseconds per day as a result of the 2011 earthquake in Japan. Does that show up in any data? Your recent graph doesn't go back that far and it's got a full scale of 2000 microseconds so a few is going to be hard to see. -- These are my opinions. I hate spam. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
