Here is the USGS event page:

[W3DRM]

Scalphunter is the closest to the epicenter. Perhaps he can fill us in on what, if anything, he felt from his location (approx 350 NNE of the quake).

I also hope he isn't impacted by a potential tsunami in the area.

[Harryca]

Looks like the sudden surge in web traffic crashed the West Coast/ Alaska Tsunami Center's servers, I am not getting any response however, I am displaying their messages on my web page http://ucweather.org/tsunamialt.php

This one seems to be working just fine. I also could not get into the AK Tsunami servers.

[Harryca]

Now their stupid Atom feed is hosed up and can't display that anymore.  Nuts!!!

Edit:  Looks like it is working now, they must have been updating it when I was trying access it but, their energy and travel times maps are not showing.

Just need to know where to go LoL

Glad you're ok.  I hope everyone up there is ok, too.

7.7 is a strong quake.  There has been aftershocks, too.

[Scalphunter]

after shocks of 5.8,4.8,and 5.1 mag so far.....

John

[Scalphunter]

Looking where the aftershocks are and knowning where the fault lines run in that area  the aftershocks are moving offshore into deeper water.

[Scalphunter]

Another 4.6 to the west of the orginal quake.

[Scalphunter]

on warning for Hawaii they are saying an 7 foot wave is possible. Have not seen anything like that in writing. That was off fox news.

[Scalphunter]

The WCATWC has downgraded the Tsunami Warning to a Tsunami Advisory... which is now in effect for areas of the Alaskan Coast South of Sitka, AK.
 
This remains a serious event. The WCATWC staff has also requested that in addition to the Advisory region, residents of the Kodiak Island area should stay home, away from the beaches, and off the roads. While Kodiak, AK is not included in this Tsunami Advisory, the area could experience odd and unpredictable local currents at this time.

[Harryca]

on warning for Hawaii they are saying an 7 foot wave is possible. Have not seen anything like that in writing. That was off fox news.

They either got some bad info or just plain got it wrong.  All the reports I have seen so far have been anywhere from .2 to 1.1 feet even in BC near the epicenter.

Edit:  Looks like the highest wave so far has been 1.3 feet at Arena Cove, CA.  My website is still getting quite a few hits from this event.

 Now that this event is over with and talking to friends it is interesting that where your house is buit sure can make an difference.
Several of us are on bedrock and we did not feel anything. Those who haul fill in over muskeg and sunk pilings where the ones to feel the quake.

Down in Port Clements one fella said it seem like it lasted about 3 mins. He felt it and it kept shaking, looked out his window and his boat was rocking, he was shaking and his truck was moving.

 As to hits here on website  we zero hits. People in this area just seem to take what comes along with an grain of salt. I think in part lot of it has todo with satellite TV. Everything comes in by the bird so unless your in Anchorage or Fairbanks the TV never going to issue an warning. Even the cable comes in off the bird and rebroadcast.

My itte earthquake gadget sticker sure did the trick on the weather computer setting off the alarm within mintes of it happening.

Let you guys get back to your windstorm.

In the past 25 minutes the area of last nigth 7.7 was rocked with 6.3, 5.4, and 5.1 after shock. All of these are offshore along the QC trench.

note there is confusing info when the wave height is refered to as the increase in sea level measured by a wave bouy
i.e 2 feet
but that also is then accompanied by a decrease in sea level, e.g 2 ft
so the wave height crest to trough can also be described as 4 ft

The DART system uses underwater transponder that measures the wave in the sea column near the bottom. If 2 foot wave passes over then it is 2 feet above normal sea level un-like the wind generated waves. According to what I have read tsumani waves fall in the class as gravity waves and have long periods from  crest to troughs. There is good section on them found in NOAA web site.

yes, very long periods...12 minutes for these ones in Hawaii
normal wind generated wave period is measures in seconds (e.g 12 seconds)
