Att: hap0206 - haha, yep underground earthquakes can cause tsunamis .. as you know .. and we know how Trump feels about early warning systems ..
December 26, 2004, an extremely powerful earthquake occurred off the coast of the Indonesian island of Sumatra in the Indian Ocean. This magnitude 9.1 earthquake, the third largest in the world since 1900, generated a tsunami that reached as high as 167 feet (51 meters) and caused flooding up to three miles (five kilometers) inland.
The tsunami, not the earthquake, was responsible for the majority of the impacts, which were observed in 17 countries in Southeastern and Southern Asia and Eastern and Southern Africa. Impacts included approximately 230,000 deaths, the displacement of 1.7 million people, and roughly $13 billion (2017 dollars) in economic losses.
The extent of the losses was partly because of the lack of an official tsunami warning system in the Indian Ocean at the time and limited knowledge about tsunamis.
