No earthquake would ever cause California or any other place to "fall into the ocean" ever. Land doesn't work that way. At most a continent could be torn apart, slowly, and a new sea/ocean will fill in the gap. It would take millions of years.

Considering the most well-known fault line, the San Andreas Fault, doesn’t run parallel to the state line, not likely. Indeed, the majority of the north-south fault lines are west of the San Joaquin valley and into the Bay Area and coast.

So while the chances of losing part of California to the Pacific are not zero, it’s even less likely the state will split from Arizona, Nevada, Oregon, and Mexico along the state lines and international border.

(I live about 25 miles west of the San Andreas Fault, where it’s closest to me.)

0% land is not floating on the sea it is just land that is higher than the sea floor. For anything to “fall into the ocean” you need to break off of the rest of the land and fall into the sea, this often happens dramatically with cliffs but it’s never more than 20-30 feet on a bad year.

so i should have asked what are the odds of a chunk of cali falling into the sea? thx!

Still unlikely.

The landmass isn’t simply floating on the water, waiting to be split and separated to float off into the sunset.

Cute question though. We were asking that in elementary school in the early 1970s.

exactly awww :)
