2004 Tsunami
On December 26, 2004, the world's most powerful earthquake in more than 40 years struck deep under the Indian Ocean off the west coast of Sumatra, triggering a massive tsunami. One of the things that made this event particularly destructive is that the tsunamis struck relatively well-populated areas in the middle of the tourist-packed holiday season. Here is a timeline of the disaster:12:59 am - A massive 9.0 earthquake occurs in the Indian Ocean off Sumatra, Indonesia. The quake is so large it is felt in the neighboring countries of Thailand, Malaysia and Singapore. Huge buildings in the Thai capital of Bangkok shake under the force of the earthquake and its aftershocks. Bangkok is 1,242 miles (nearly 2,000 km) from where the earthquake took place.
1:07 am - After the quake, stations in Australia alert the NOAA Pacific Tsunami Warning Center of the earthquake and the potential tsunami threat. There are widely conflicting reports from different sources about the size of the quake. Different reports put the earthquake at magnitudes varying between 6.6 and 8.9. At the same time, an Indonesian radio station reports the death of nine villagers as the result of a tidal wave.
