I don't underestimate the power of even a small tsunami. I have friends 
rendered homeless by the Santa Cruz tsunami (their boat being their only 
home).

Though I can understand one is underwhelmed by a mag 6.x earthquake in 
that region considering I believe more than 20 6+ ones happened there 
since the first mag 7.2 earthquake that happened 2-3 days before the mag 
9 one.

Most recent ones:
