It was an one-two punch because either one by itself unlikely would have produced the disaster: the earthquake not only produced the tsunami, it also sunk the coastline about 4 feet rendering tsunami barriers useless. I read somewhere their tsunami barriers where just high enough to stop the tsunami but the coastline sinked. No engineer could have predicted that. |

But that's what I'm saying! Tsunamis can't happen by themselves. They're caused by earthquakes (or volcanic eruptions, nuclear explosions, or other literally earth-shaking events). The odds of a record-breaking earthquake co-occurring with an extreme tsunami approach 100%. Similarly, it's not at all surprising for the coastline to sink in an earthquake.
