I don't know how it works in the states, but the warning was issued 3 minutes after the quake and I assume that meant the EAS went off right away. But in Canada, it did not appear on Environment Canada's website until 35 minutes later.... and we don't have any mass notification warning systems. Hope these people are okay.

There was a 5.8 aftershock a few minutes later as well.

This is a transform (strike-slip) fault, so the danger there actually is a significant tsunami is lower than if it was on a subduction fault - you can still have thrusting motions on a strike slip fault so a tsunami is possible, but probably not that large.

It would appear first on this DART buoy: http://www.ndbc.noaa.gov/station_page.php?station=46410

Listening to Prince Rupert RCMP scanner. Lots of conversation about watching the shore, but nothing about damage.

They are expecting the wave any time now as it's arrival time was 10 minutes ago on an island nearby. Listening here on the VLC player link. It's not compatible with Windows Media Player.
