NOAA: 120 Years of Earthquakes and Their Tsunamis: 1901-2020

Note that while the great majority of all earthquakes occur at plate boundaries, these tsunami-causing earthquakes mostly occur at convergent plate boundaries.

National Oceanic and Atmospheric Administration (NOAA): This animation shows every recorded earthquake in sequence as they occurred from January 1, 1901, through December 31, 2020, at a rate of 1 year per second.

The earthquake hypocenters first appear as flashes and then remain as colored circles before shrinking with time so as not to obscure subsequent earthquakes. The size of each circle represents the earthquake’s magnitude while the color represents its depth within the earth.

This animation also highlights significant tsunamis generated by some of these earthquakes. When the following earthquakes appear they will also have their tsunami’s “energy map” that shows each tsunami's maximum modeled wave heights on the open ocean:
