Deigo Garcia military base unaffected by tsunamis
The key United States military base in the Indian Ocean has been unaffected by the tsunamis which have devastated parts of Asia, The Washington Post has reported.

Diego Garcia, a British territory about 1,500 kilometres south of India, hosts about 3,200 US military personnel and civilian contractors and many US long-range bombers and Navy ships.

Lieutenant Colonel Bill Bigelow, a spokesman for US Pacific Command in Hawaii told the newspaper the US base was apparently safe.

"There are no reports of any damage there," Lt Col Bigelow said.

"Diego Garcia Navy base reports no damage from quake, tsunamis"

"U.S. was aware that a deadly Tidal Wave was building up in the Indian Ocean"
Shame they didnt tell Thailand, Sri Lanka, the easter coast of India and Indonisia. Its good to talk :?

"From the US National Oceanic and Atmospheric Administration :

Dec. 29, 2004 — NOAA scientists at the Pacific Tsunami Warning Center in Hawaii went to work within minutes of getting a seismic signal that an earthquake occurred off the west coast of Northern Sumatra, Indonesia.
NOAA issued a bulletin indicating no threat of a tsunami to Hawaii, the West Coast of North America or to other coasts in the Pacific Basin—the U.S. area of responsibility.


NOAA scientists then began an effort to notify countries about the possibility that a tsunami may have been triggered by the massive 9.0 undersea earthquake.

The Pacific Basin tsunami warning system did not detect a tsunami in the Indian Ocean since there are no buoys in place there. Even without a way to detect whether a tsunami had formed in the Indian Ocean, NOAA officials tried to get the message out to other nations not a part of its Pacific warning system to alert them of the possibility of a tsunami.
However, the tsunami raced across the ocean at speeds up to 500 mph.

Below is the timeline of agency’s actions once the undersea earthquake was detected by the NOAA Pacific Tsunami Warning Center in Hawaii.

(All times listed below are Hawaii Standard Time or HST.)

At 2:59 p.m. Hawaii Standard Time (HST) on Christmas Day a large earthquake occurred in the Indian Ocean near Sumatra, Indonesia.

At 3:07 p.m. the resulting seismic signals received at the NOAA Pacific Tsunami Warning Center (PTWC) from stations in Australia triggered an alarm that alerted watchstanders.

At 3:10 p.m. PTWC issued a message to other observatories in the Pacific with its preliminary earthquake parameters.

At 3:14 p.m. PTWC issued a bulletin providing information on the earthquake and stating there was no tsunami threat to the Pacific nations that participate in the Tsunami Warning System in the Pacific (ITSU). These member nations are part of the UNESCO Intergovernmental Oceanographic Commission (IOC) and the International Coordination Group for the Tsunami Warning System in the Pacific (ICG/ITSU). India, Sri Lanka and the Maldives are not part of the Pacific system.

At 4:04 p.m. PTWC issued bulletin No. 2 revising the earthquake magnitude to 8.5. That bulletin stated no tsunami threat to the Pacific but identified the possibility of a tsunami near the epicenter. No additional information regarding the formation of a tsunami was available.

At approximately 4:30 p.m. HST PTWC attempted to contact the Australia Met Service with no luck but were successful in contacting Australia Emergency Management.
They confirmed they were aware of the earthquake.

At approximately 5:30 p.m. Internet newswire reports of casualties in Sri Lanka provided PTWC with the first indications of the existence of a destructive tsunami.
Indications are that the tsunami had already struck the entire area by this time, although we have not been able to obtain arrival times.

At approximately 5:45 p.m., armed with knowledge of a tsunami, PTWC contacted the U.S.Pacific Command (PACOM) in Hawaii.

At approximately 5:45 p.m., PTWC received a call from a Sri Lanka Navy Commander inquiring about the potential for further tsunami waves from aftershocks.

At approximately 6:00 p.m. the U.S. Ambassador in Sri Lanka called PTWC to set up a notification system in case of big aftershock. He said they would contact Sri Lanka Prime Minister’s office for such notifications.

Continuing news reports gave increasing and more widespread casualties.

At approximately 7:25 p.m. the first reading from the Australian National Tidal Center gauge at Cocos Island west of Australia gave a reading of 0.5m crest-to-trough.

At 7:25 p.m. the Harvard University Seismology Department reported its preliminary Centroid Moment Tensor solution that indicated a magnitude of 8.9.

At approximately 7:45 p.m. PTWC contacted the Australia Bureau of Meteorology and advised them about the increased earthquake magnitude and the 0.5m reading at Cocos Island, as well as the possibility of a destructive tsunami impact on Australia’s west coasts.

At approximately 8:00 p.m. PTWC re-contacted PACOM to advise of increased earthquake magnitude and potential for further tsunami impacts in the western Indian Ocean.

At approximately 8:15 p.m. Australia Bureau of Met called PTWC to advise they had issued an alert to their west coast.

At approximately 8:20 p.m. NOAA National Weather Service Pacific Region director contacted PTWC to report PACOM said no tsunami was observed at Diego Garcia in the Pacific.

At approximately 10:15 p.m. PTWC spoke with U.S. State Department Operations and advised them about the potential threat to Madagascar and Africa. They set up a conference call with the U.S. embassies at Madagascar and Mauritius, and PTWC advised them of the situation.

At 5:36a.m. on December 27 PTWC issued a third Tsunami Information Bulletin for this event informing the Pacific that small sea level fluctuations from the Indian Ocean tsunami were being observed in the Pacific, probably from energy that wrapped around south of Australia."

Thanks tom

BBC radio ran an interview a couple of days ago with someone from the NOAA Pacific Tsunami Warning Center in Hawaii. I understood him to say that they hadnt been in touch with any Indian Ocean countries. He made the point that without access to real-time tide gauge data it isnt possible to determine quickly that a major tsunami event is in progress.

As always, no doubt lives could have been saved if things had been done differently. Hindsight is a wonderful thing. Without a proper system put in place by the Indian Ocean countries, I imagine that a false tsunami alarm flashed across the region could have led to deaths and injuries through panic.

The USGS apparently uses automated monitoring. Links of the link below indicate that changes to that site take place without human intervention and are only reviewed later by a human geologist. The data was there but those who should have been listening weren't.

Also looking at this animation (remembering that its a simulation of course) DG must have been out of 'the line of fire'. Its south of the Maldives as I recall. Somalia on the other hand must have been in line to receive whatever went south of India and Sri Lanka.

The Ickes of this world are going into two schools of 'thought'.

1. DG must have been trashed, the multinational ‘residents’ are all shark food and it’s being covered up. (How difficult would that be to keep quiet?)
Or:

2. DG must have had early warning and prepared ( put up its force field? :roll: ) while the third and developing world in the region were kept in the dark, deliberately.

The physics of tsunamis have been explained in layman terms (until last Sunday I thought it was a trendy management speak word for a tidal wave ) and I can now understand why DG was spared.

Diego Garcia Personnel Safe, Facilities Intact Following Tsunami

Diego Garcia, British Indian Ocean Territory – Navy personnel on board Naval Support Facility Diego Garcia in the Indian Ocean are safe following the earthquake and subsequent tsunami that had devastating effects on Southeast Asia. Facilities and operations were not affected.


Favorable ocean topography minimized the tsunami’s impact on the atoll. Diego Garcia is part of the Chagos Archipelago, situated on the southernmost part of the Chagos-Laccadive Ridge. To the east lies the Chagos Trench, a 400 mile long, underwater canyon that ranges in depth from less than 1,00 meters below the surface to depths that plunge to over 5,000 meters. It is one of the deepest regions of the Indian Ocean.


Diego Garcia is located to the west of Chagos Trench, which runs north and south. The depth of the Chagos Trench and grade to the shores does not allow for tsunamis to build before passing the atoll. The result of the earthquake was seen as a tidal surge estimated at six feet.



Nothwithstanding that the actual event (from quake to tsunami rolling ashore) develops faster that scientists can calculate what effect if any it'll have, there are those blaming the US for a lack of warning who seem to think that there are mud huts on the affected coasts with TV, Internet and mobile phones and the USGS have their addresses and numbers and speak the language.
