Large but not really major, thank goodness... Even though it was a very shallow quake I doubt that it would generate a tsunami of any great size. Just
doesn't have the energy to do that, really. The mag 7.7 Sth of Masset (BC) back on Oct 28 last year (depth 20 km) didn't cause much of a tsunami
either and it wasn't very far south of this one.
However it could still be problematic in some of the more local regions they have mapped. As for Hawaii I'd say you have nothing to worry about if you
live there, folks.

Hi TA. I'd agree that it's looking like a more typical mainshock/aftershock sequence. We have to hope so, anyway.
If it is a typical one, then we can expect a whole bunch of smaller events there in the coming days. TA knows this but I'm mentioning it for when
people say "OMG look at all the aftershocks... Is that normal?" Yes, it is
normal with such a shallow event of this size, and we can expect one
or two even in the mag 6 range.
If we don't
see dozens of aftershocks in the coming hours and days, that would be a worry.
EDIT: Just for comparison, this is what the quake map looked like on Nov 3, 2012 -- six days after the mag 7.7 event off BC:
There are 89 events on that map, including two in the mag 6 range and nine in the mag 5 range. This is a very typical aftershock sequence for an event
like this, and we can expect something similar with today's quake.
