Shaking me into Action

Not a lot of posts lately,  even though we have a lot to talk about…  I’ll try to get some written here in the next couple days,  so my apologies if an avalanche of posts come your way this week.  We had quite the earthquake shake this morning,  so I at least have to post about that!

At 3:58am this morning,  Teen and I were roused from our sleep to a 5.8 quake.  It was actually centered a little over 100 miles to the southeast of us closer to Haines,  AK,  but we sure did feel it here.  One of the stronger quakes we have seen in a couple years.  It could be that being on the second floor of the hangar helped to increase the swaying motion we felt too.

Here is the map location from the Alaska Earthquake Center (who will be here this weekend servicing their remote sensing sites by helicopter and operating from the hangar).

June 4th,  2014 Earthquake at 3:58am centered 49 miles west-southwest of Haines,  Alaska and 113 miles east-southeast of Yakutat

Red lines on the map indicate our major fault lines.  If you move straight toward the ocean from the quake’s location (at a 45º angle down and left),  you can kind-of see Lituya Bay,  home of the largest wave ever recorded on earth.  In the 1958 quake centered there,  the hillside at the head of the bay collapsed,  creating a splash-wave that denuded the forest over 1,700 feet up the opposite hillside.  By the time the wave hit Cenotaph Island and the three fishing boats anchored in the bay,  it was between 30 and 100 feet high,  sinking two of the three boats.  It was quite a ride!  I’ll attach some photos from the ’58 quake below.

The region around Yakutat has had a lot of quake activity lately,  but most were too weak to feel.  Lots of little quakes tends to mean the plates are slipping gradually to relieve the pressure,  instead of having a really big catastrophic one like the 1958 and 1899 quakes that killed people around here.  We like little ones,  in other words…  No Tsunami warning was issued.

Hard to tell the damage in this,  but it nearly topped the visible hillside!

Taken a month ago,  you can clearly see the brown stripe of the "bathtub ring" along the shore,  where the spruce forest was killed and only willow and alder grows today
