PTWC issued bulletin No. 2 revising the earthquake magnitude to 8.5 based on later seismic energy. That bulletin stated no tsunami threat to the Pacific but identified the possibility of a tsunami near the epicenter. PTWC attempts to contact the Australian Bureau of Meteorology to verify if they received the bulletin. As their main line was busy, they called Emergency Management Australia instead. EMA indicated Australia was aware of the earthquake.
PTWC received a call from a Sri Lanka Navy Commander inquiring about the potential for further tsunami waves from aftershocks. The U.S. Ambassador in Sri Lanka called PTWC to set up a notification system in case of big aftershock.PTWC issues a message to the Tsunami Bulletin Board that goes by e-mail to international tsunami scientists and organizations. The message reports that based on the Reuters news wire article, a destructive tele-tsunami was generated by the Sumatra earthquake. PTWC receives a call from a Sri Lanka Navy Commander inquiring about the potential for further tsunami waves from aftershocks. The U.S. State Department Operations Center calls
PTWC and is advised of the potential threat to the western Indian Ocean and eastern Africa. They agree to set up a conference call with U.S. embassies in the region. The U.S. State Department Operations Center sets up a conference call with the U.S. embassies at Madagascar and Mauritius.
The Next day 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
How ordinary people communicate???
A son of a fisherman who works in Singapore, He decided to phone home When he asked what was happening in Nallavadu she told him that seawater was seeping into their home. He asked his sister to quickly leave their home and to also warn other villagers to evacuate the village. 'Run out and shout the warning to others'. The warning from Vijayakumar, collaborated at this time by a second overseas telephone call from Gopu, another villager working abroad, was broadcast across the village using the loud-speaker system. The village's siren was sounded immediately afterwards for the people to evacuate.
People who have never blogged before have turned to the web to share their gripping accounts and upload their photos and home video, offering a raw, unedited perspective on the human tragedy.
The British Broadcasting Corporation (BBC) joined the ranks of mainstream media now clicking into the blogosphere by publishing first-hand blog reports and images from many of these non-professional eyewitnesses.
A blog is now defined in Merriam Webster's Dictionary as a "website that contains an online personal journal with reflections, comments, and often hyperlinks provided by the writer". In light of the heroic service provided by these dedicated bloggers in informing relatives in the West about the missing, the timely and sensitive postings of photos of located orphaned children, and the call for relief action, that definition may be compassionately broadened in the near future. As 2004 ended, the world witnessed in this digital era the poignant pleas of survivors, families desperately seeking information for loved ones and disturbing images transmitted through the World Wide Web.
Paola di Maio survived the tsunamis's impact on the beach in Phuket, Thailand, and with available Internet connectivity on the island, communicated to Peter Griffin, a communications consultant in Mumbai, India, that the most pressing need was for accurate information. These Internet evangelists quickly set up the Sea-Eat blog, or The Southeast Asia Earthquake and Tsunami Blog, tsunamihelp.blogspot.com.
Australian Geoffrey Huntley, 22, at www.waveofdestruction.com, started his blog immediately after the tsunami hit. He was not prepared for the sheer amount of traffic and his server crashed many times. His site went from 39,000 page serves, a web page that has been viewed by one visitor, to over 3 million in less than 48 hours.
Other bloggers, such as John Lebkowsky (polycot.com), are even more committed to discussions on what went wrong since the world knows all too painfully that there was no available tsunami detection information in the Indian Ocean and apparently no one at the warning center had the telephone numbers of their neighboring scientists in Indonesia, Malaysia and eastern India.
Conclusion: The tsunami killed many people as there were no detectors at the Indian ocean so al few people's life were saved and communication was not so effective. after the 2005 major actions have been taken place they have a warning system where it would help to predict earthquakes in the ocean
