An M7.5 earthquake has just occurred off southern Alaska at 8:58:16 1/5/2013 UTC (11:58:16 pm 1/4/2013 local time), just at the NW tip of the area identified in the previous blog as having undergone a rapid change in the last several days. Hypocenter depth was 9.9 km, and a tsunami warning has been issued.  More as the story develops. A screenshot from the earthquake viewer is shown below.  The mechanism for this event was right lateral strike slip (horizontal slip) so a great tsunami is probably unlikely.
