[Geysers] Tsunami (Reilly)

[Karl and Lori Hoppe]

For question #1, try to visualize a wave as it travels
down a length of rope.  As the wave gets towards the
end, the tip of the rope is pulled back so it can
travel up and back down the wave.  As anyone who's
been snapped with a towel knows, it's the tip of the
wave that does the most damage...  I would suppose
this is what would happen to water in a tsunami-type
wave.  The water is getting more shallow so the wave
has to get higher.  The shoreline is finally pulled
way back so that it can travel up to the highest
amplitude, then travels back down as the wave crashes
onto the shore.

For question #2, check out:

Click on the big picture (says "Multimedia Feature"). 
Let the animation play (first showing you a
before/after slide of damage in Sri Lanka).  A map of
that section of the world will come up and you can
click the arrow to see a simulation of the tsunami. 
That will answer question #2.  The wave basically
traveled up along the coastline of India - both east
and west.
