Original Note:
The 5 Dec 2024 California earthquake did not produce a tsunami because it was too small and a strike-slip event, which cannot produce the vertical displacement of the seafloor necessary for tsunamis. https://www.usgs.gov/faqs/what-it-about-earthquake-causes-a-tsunami https://earthquake.usgs.gov/earthquakes/eventpage/nc75095651/executive Publicly available seismic data clearly shows it was not an explosion: https://www.usgs.gov/faqs/how-can-you-tell-difference-between-explosion-and-earthquake-seismogram https://www.iris.edu/app/station_monitor/#2024-12-05T00:00:00/RE-MTCL3/map/
