Reminds me of this man, over exactly 100 years ago. To quote:
On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of tetraethyl lead (TEL), in which he poured TEL over his hands, placed a bottle of the chemical under his nose, and inhaled its vapor for sixty seconds, declaring that he could do this every day without succumbing to any problem.
So tsunamis are definitely a threat generally from earthquakes and an earthquake of this size can make it deadly. Unlike the San Andres faults that cause most California earthquakes ( which wouldn’t produce significant tsunamis) this earthquake occurred in a discordant part of the pacific oceanic crust called the Mendocino triple junction - the intersection of the San Andres fault, Cascadian subduction zone (where the Pacific crust is plunging under the North American continent, feeding features like Mt. St Helens), and the Gorda plate (the last remnant of the precursor to the pacific plate, the Panthalassic Ocean that surrounded Pangea).
