Earthquake dynamic friction to zero


CR: Don’t be afraid—ride it out, enjoy it … I know a seismologist, who, when an earthquake occurs, will just drop to the floor and lie spread-eagle on the ground and try to determine which way the waves are coming from—I didn’t react fast enough to do that the other night.

Now, I really don't think she meant that all eastern earthquakes are a 'fun ride'.  If so, then there is no meaning to my life.  :(

However, she did mention that the Japan earthquake drove the dynamic friction to zero.  I've been postulating that this happens in most earthquakes, but especially 'super quakes', such as Kobe, Japan, or Armenia.  It's a question of luck, whether you are right on the 'hammer zone'.
