How Tsunamis Work

Ted-ed provides another excellent animation about tsunamis, how they form, and what can be done about them.

As usual with TED-ed animations, this one has a nice mix of general and very specific information which should be information for just about any casual viewer. These forces of nature kill tens of thousands of people and, regardless of whether you live near the coast, could directly impact your life someday (as the people of Japan found out after Fukushima). In any event, we can pretty much guarantee that you will see the word used in a news headline down the road.

The funny thing about tsunamis is that they are impossible to predict, and even after they occur, their actual effects also are difficult to predict. Sometimes, a seemingly horrible underwater earthquake will cause little damage (South America, 2014), while other times, one with just the right formation will take out a huge swathe of a country (Fukushima).

Tsunamis are a fact of life, and interest in them spikes every time... there is a tsunami. So this is an evergreen topic.

From the web page:
The immense swell of a tsunami can grow up to 100 feet, hitting speeds over 500 mph -- a treacherous combination for anyone or anything in its path. Alex Gendler details the causes of these towering terrors and explains how scientists are seeking to reduce their destruction in the future.
