If somebody happens by this idling site, the Pacific Tsunami Warning Center has a warning out for the Northern Marianas.
Their estimate is about 8:53 Zulu -- about 6:53 this evening. They say its magnitude was 7.9 with no reports of damage or waves... But that's bulletin one.
From Japan I'm hearing 8.8 with large waves and major damage. Check out Earthquake-Report.com. They claim it's the largest quake ever recorded in Japan.
Excerpted from bulletin #9:
SAIPAN US 15.2N 145.7E 0916Z 0.65M / 2.1FT 30MIN
So it looks like 2.1 feet at 7:16 pm
I wonder where the gauge is...
