I notice, by "exploring" the island through Google Maps, that there is a lot
of vegetation
that is growing in straight lines, particularly on the eastern leg of the
atoll. I wonder if
this is an agricultural endeavor, ie groves or orchards of some sort. I
suppose they could
have also been planted to replace harvested timber or for wind breaks. Or
maybe it could
be some species that naturally grows in straight rows and columns. :-)

Also - I don't recall Diego Garcia being mentioned in the news during the
2004 tsunami
so I googled "diego garcia tsunami" and was interested to find that the
island largely
escaped damage primarily because of the topography of the surrounding ocean
floor.

A lot of interesting info concerning the tsunami and DG....including
"conspiracy theories", etc.
There is a lot of satellite imagery of the base taken at different times. I
noticed a lack of
fighter aircraft in all images I've seen. I would have thought there would
be a contingent of
fighters for defense of the base. Maybe it's considered unnecessary given
the remote location.
