I called my son at 2:00 a.m., yes, I was still up. He was home and said nothing had happened yet. I see it passed by Japan so I assume all's well?
The Emergency nuclear attack, amber, and tsunami warning Broadcast System issued a tsunami warning to Alaska coastal areas last night, advising that homes are not built to withstand a tsunami, then called it off. An 8.3 is common enough in the region where it occurred that it might be considered normal, about the top end of the range.
Nary a hiccup. The islands saw a cm level change, even the worst Japan saw was a 1 M wave.... pretty mild all round.
