4. Just got a phone alert here in Japan

While everyone had their attention focused on some islands between Okinawa and the Kyushu mainland, a big M8.7 mfer hit off the coast of Kamchatka. There's a 10ft tsunami evacuation warning for Osaka east/northward, and a tsunami alert for the rest of Japan's Pacific coast, as well as nearly the entire coast of Hokkaido.

in Santa Cruz. That's a step below a warning, and we've had a couple of those in the 16 years I've lived here (actually in Capitola) without incident, except for boats in the harbor being sloshed around a bit after the big quake east of Japan some years ago that did so much damage there.

9. LAPD just announced a warning. We live about 5 miles from the beach, but about 1 mile from the L.A. port.

I heard it was only going to be an issue with boats at marinas and ports being roughed around. I recall years ago this happened in Marina Del Rey (or thereabouts) and there was quite a bit of damage.

Hawaii is the trouble spot.
