If the island's elevation is only 4 to 22 feet high, that makes
sense.
But why was there so much damage to the coast of Somalia, another
2000
miles further west, and no damage to DG?? Would they tell us if
there
really was damage on DG??

Nah, it's all a big secret to get you conspiracy kooks going!

But actually it probably has a lot to do with the mechanics of the
wave itself
and the sea floor/bed around Diego Garcia itself. The wave may have
'flowed'
around Diego Garcia, but when it reached Somalia it had nowhere else
to go but
up the beach.

It's pretty simple physics.

It all has to do with something called "run-up".........basically, it's
how far the water travels inland which is determined by the sea floor.
USGS has an online walk through on the mechanics of the tsunami. I am
a survivor of the great Alaskan earthquake and subsequent tsunamis in
1964. Did you know that since the initial temblor (off the coast of
Sumatra) there have been a total of 46 exceeding 5.0......and that
there now are indications that a wave was generated as well that
entered the pacific. Interesting stuff here.

Yes, there have been a lot of aftershocks. I subscribe to the the service he

Which notifies me of earthquakes exceeding 5.5 anywhere in the world or 4.5 in
the USA.
