Earthquake Science, and the Disaster That Created It

The video discusses the 1964 Alaskan earthquake, the largest recorded in North America, and its impact on modern earthquake science. It explains plate tectonics, subduction zones, and different types of faults. The video highlights the scientific advancements made post-earthquake and the establishment of institutions like the US Geological Survey's Earthquake Hazards Program. It concludes with a call to support SciShow Infusion.
