Nämä tiedot (maanjäristys-bulettinit) olivat myös Suomessa (ainakin GTK:ssa) lähes mainittuna lähettämishetkellä. Eli suomalaiset viranomaiset saivat tiedon mahdollisesta tsunamista hieman yli tunti (1h 5min) maanjäristyksen jälkeen. Noin 2,5 tuntia järistyksen jälkeen kerrottiin jo tsunami-uhreista Sri Lankassa.

Tsunami Warning Timeline
Here is a timeline showing what Pacific Tsunami Warning Center geophysicists knew, when they learned it, and how they responded.
(Hawai'i Standard Time Dec. 25 — some times are approximate)
2:59 p.m. — Magnitude 9 earthquake occurs in the Indian Ocean near Sumatra. (Initially calculated at 8.)
3:07 p.m. — On-duty personnel at Pacific Tsunami Warning Center receive automatic alerts of large quake.
3:10 p.m. — Warning center issues e-mail notice with preliminary earthquake information. E-mail goes to Pacific nations, news media, government agencies, individual subscribers.
3:14 p.m. — Warning center issues to its Pacific Ocean partners a bulletin that no tsunami threat exists in the Pacific.
4:04 p.m. — Warning center bulletin revises quake to 8.5, warns of possible tsunami near the epicenter.
4:30 p.m. — Warning center reaches Australia Emergency Management, which confirms it is already aware of quake.
5:30 p.m. — News reports of casualties in Sri Lanka on the Internet give Warning Center first confirmation that a destructive tsunami exists.
5:45 p.m. — Warning Center alerts U.S. Pacific Command in Honolulu, and receives query from Sri Lanka navy commander asking about further waves generated by aftershocks.

7:25 p.m. — Australian-owned Cocos Island tide gauge, one of very few gauges in the Indian Ocean, gives a modest 1 1/2-foot wave reading from trough to crest. Harvard University Seismology Department reports earthquake magnitude at 8.9.
7:45 p.m. — Warning center warns Australia Bureau of Meteorology of increased calculated quake strength and the Cocos reading, and possibility of tsunami strike on Australian west coast.
8 p.m. — Warning center reports to the U.S. Pacific Command the increased magnitude and Indian Ocean tsunami threat.
8:15 p.m. — Australian Bureau of Meteorology reports it has issued tsunami alert for nation's west coast.
