Remembering the deadliest tsunami in history
CNNTwenty years ago on December 26, a 9.1-magnitude earthquake triggered massive tsunamis across the Indian Ocean, sending waves slamming into the coasts of 14 countries with devastating power. The 2004 Indian Ocean earthquake and tsunami was one of the deadliest disasters in modern recorded history, killing an estimated 230,000 people and affecting millions. The lack of an early-warning system and minimal sea-level data left seismologists scrambling to determine the earthquake’s magnitude and exactly if – and where – the waves would hit. The National Oceanic and Atmospheric Administration called the tragedy a “wake-up call” and has since ramped up investment in tsunami science and the deployment of buoys used in tsunami monitoring systems to detect seismic events quicker and more accurately.
