I enjoy the articles on Livescience. The information on #2 alaska's 1964 earthquake has an error on the length of "shaking lasted about 3 minutes", The earthquake lasted approximately 4.5 minutes and is the most powerful recorded earthquake in U.S. history. https://earthquake.usgs.gov/earthquakes/events/alaska1964/

The fault rupture was over 100 miles long, which contributed to the length of time of the earthquake.

The study of this earthquake contributed to the acceptance of the Plate tectonics Theory.

In addition there were many Tsunamis both tectonic and landslides caused. At least 4.
Kodiak AK that I assume was tectonic (underwater movements of the earth around the fault) that also hit California among other places.
Seward AK, Cheniga AK, and Vadez AK from separate local underwater landslides each starting from separate sources.

I personally experienced this Quake in Anchorage Alaska.

Thank You for all the articles.
