Diego Garcia Escapes Tsunami Damage
The American navy base Diego Garcia in the Indian Ocean was unaffected
by the Asian Tsunami.

Officials said the Diego Garcia Navy Support Facility, which houses
about 1,700 military personnel and 1,500 civilian contractors, suffered
no damage related to Sunday's earthquake and ensuing tsunamis. Diego
Garcia, the southernmost island in the Chagos Archipelago, sits about
1,000 miles south of India and roughly 2,000 miles from the
earthquake's epicenter.

No, I don't think they will reveal much baout, for obvious reasons.
And I do not think they were affected much, because the surrounding
waters reach depths of more than 100m just several hundred m from shore.

It has to do with the deep ocean close to shore as well as the steep slope of the
island. Like the ocean surf the tsunami energy concentrates only when the wave hits
shallows. In Diego Garcia the water rose 6 ft.
