write a post that describes the key elements of the Thunderbird and Whale story, and which parts allow for the interpretation that this story is rooted in the reality of earthquakes and tsunamis.

How are these two accounts related, and how are they both relevant for confirming the occurrence of Cascadia Subduction Zone megathrust events?
