A tree's age can be easily determined by counting its growth rings, as any Boy or Girl Scout knows. In good growing years, when sunlight and rainfall are plentiful, the growth rings Then using tree ring dating methods, it may be possible to date earthquakes occurring before historical records were kept.

A few of its blue-green feathery leaves flagged from the top of what otherwise looked like a snag.
