The tsunami that affected the coasts of the Indian ocean on December 26, claimed close to lives, mainly on the island of Sumatra, Indonesia, which suffered overwhelming devastation. This article asks whether a tsunami warning system is needed in the Indian Ocean, where the probability of experiencing a similar catastrophe is very small. In addition, other alternatives, including land use planning and education focused on tsunami risk management, are presented.
The Dec 23 tsunami killed around people along the coastlines of the Sunda Strait, capping a year of earthquakes and tsunamis in the vast archipelago, which straddles the seismically active Pacific Ring of Fire. No sirens were heard in those towns and beaches to alert people before the deadly series of waves hit shore. Seismologists and authorities say a perfect storm of factors caused the tsunami and made early detection near impossible given the equipment in place.

Triggered by a massive undersea quake off the coast of Indonesia, the Asian tsunami pounded Indian Ocean coastlines with waves up to feet high, catching victims and the world's leading scientists by storm. Are we better prepared for the next big one? Where will the next one hit?
On 26 Decthe fourth-largest earthquake in a century erupted underwater off the Indonesian province of Aceh, causing a tsunami that accelerate to speeds of more than kilometres per hour and barreled one-fifth of the way around the earth. More thanpeople died in 14 countries in Southeast Asia and South Asia, and as far away as Africa; most were women — in some places three times the number of men — the elderly and children. In all, nearly 2.
A study carried out six years ago by the Geological Society of London that accurately predicted a possible major hazard emerging from Anak Krakatau volcano could have been used as a basis to prevent Indonesia's latest natural disaster, which has killed more than people. The study said a tsunami could be triggered by a collapse of Anak Krakatau's flank as the volcano is partly built on a steep wall of the caldera resulting from the eruptions. Using a numerical model, it simulates both Anak Krakatau landslides and the tsunami propagations, detailing the tsunami's possible travel time and wave amplitude when hitting various coastal areas including Sumur, Carita, Labuan and Anyer in Banten province - on the western tip of Indonesia's most populous island, Java - and parts of Lampung province, in the southern tip of the country's second-most populous island, Sumatra.
The French tsunami alert centre, CENALT, has already provided more than 24 tsunami information alerts and issued three tsunamis advisory warning messages since the beginning of its operations in French coasts are mainly exposed to seismic activities coming from the North African coast where tsunami waves can hit France within one to two hours after the outbreak of an earthquake and from the Ligurian Sea, where tsunami waves can reach French shorelines in less than 10 minutes after a tremor. Three other early warning systems exist in the Pacific operational for 50 yearsin the Indian Ocean, and in the Caribbean.
