Whose research first linked undersea earthquakes to the great 2004 Indian Ocean tsunami?
Quick Answer
Scientists using seismic and geodetic data identified the massive Sumatra-Andaman earthquake as the source. The event led to major improvements in Indian Ocean tsunami monitoring.
The Full Story
The 26 December 2004 Sumatra-Andaman earthquake was one of the largest earthquakes ever recorded, with a moment magnitude of about 9.1 to 9.3. Seismic, satellite, and coastal data showed that the seafloor uplift near Sumatra generated the Indian Ocean tsunami. The disaster killed more than 200,000 people across multiple countries. It transformed global awareness of tsunami risk and accelerated the creation of warning systems in the Indian Ocean region. The event is now a central case study in natural-disaster science and preparedness.
