Was there actually a tsunami?

Edit: My friend in the Bay Area says “Nothing happened and they called [the warning] off.”

Felt it like a hundred miles inland too. Really deep slow rumbles here.

I hope you have moved to higher ground if you live in northern California

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).

I found an estimate of when the wave will hit the shore. Looks like it will hit the Bay Area in just a few minutes
