We could also be hit by a meteor.

With regard to an massive meteor.
The Tidal Wave would probably be the least of our worries.

If the meteor was a few miles long it probably would not only create giant Tidal Waves, but a blast that would be kin to setting off all the nuclear weapons in the world a million times over.
We would be DOOMED.

One problem is there seems to be an obsession with this exceedingly unlikely but really dramatic things; Yellowstone Caldera, La Palma collapsing, etc....

And things that are not only likely, but PROBABLE in the next few decades...a magnitude 7-7.5 earthquake on the Hayward Fault in Oakland and Berkeley, or in Salt Lake City...or in any of a number of other places...that would kill 5,000+, cost hundreds of billions of dollars, and make 9/11 look like a joke...are basically ignored.
