Here's What a 9.2 Earthquake Can Do to a City

It's been fifty years since the Great Alaska Earthquake, the biggest ever to shake the United States. At magnitude 9.2, it leveled a city and was felt as far away as Texas. This fascinating short documentary reveals how it also led to a scientific breakthrough.


At the time of Great Alaska Earthquake, the theory of plate tectonics had only recently been considered viable. Scientists were still debating it, and seeking more evidence to bolster claims on both sides. Ultimately, evidence gathered from this quake wound up being one of the deciding factors that led to the geology community accepting plate tectonics.

This documentary was created by the US Geological Survey, a group of civil servant scientists who study the earth and the environment. USGS scientists were among the first on the scene at in 1964 after the quake, and it was their data-gathering that helped change the way we understand the planet's crust.

One thing people don't realize about earthquakes is... it's the only natural disaster that doesn't actually kill people. People "only" die as a result from being hit or crushed by man-made objects... not from the earthquake itself.
