    Question Earthquakes

    There have been lots of earthquakes in the Denali area and Southcentral AK lately. How does that affect your cabins? And foundations?

    I haven't heard of any damage this year. Most cabins are so flexible that they are virtually uneffected by substantial earthquakes.

    In 2002 a 7.9 struck 45 miles east of Cantwell. That is less than 100 miles from my house. I didn't even get a single crack in my drywall. There was limited damage in Cantwell itself. At my hardware store we lost one bottle off the shelves. Really not that big of deal. It knocked the Trans Alaska Pipeline off it's seismic supports without a drop leaking. The Parks and Richardson Highways had some substantial cracks, but they were repaired quickly.

    I'll take the risk of earthquakes over the risk of hurricanes and tornadoes any day

    I didn't realize anything in FBKs was damaged. Sorry I made light of it. I drove from Talkeetna to Delta the long way around and back down to Talkeetna through Fairbanks the week after the quake and didn't hear of too many problems. I figure that if that's all a 7.9 is going to do that close to home I am going to be fine for a long time

    The 7.9 didn't damage anything huh? I guess it was a good thing that the earthquake was a roller and not a shaker. If it had been a shaker, like the 64 earthquake, we might have had more damge then just roads and such.

    Picture taken in this link is near fielding lake, Notice something wrong with the buildings?

    Here's another little tidbit from up Mentasta way.

    My wife was in her coffee shop in Glennallen on the phone with me when this happened. She caught a few bottles coming off the shelves and we had to relevel the cabin. The most exciting part for her was watching the waves come down the highway and her Van jumping in the air and landing about a foot from where it was parked. Damage to the school and a few home fuel tanks tipped over, but I don't believe there was anybody killed or seriously hurt.

    Mentasta got the brunt of it if I remember right. Everything worked out ok in the end? Or did the cabin need extra re-enforcement?

    It's a small cabin with the ultimate foundation. We were in a tent at -25 when we started. Scaped the snow and as much vegetation back as possible. Layed two all weather 2 X 12's on the ground, set a spruce chunk on top, used 2 X 4's and plywood to get the stringers level and went from there. I have wedges on top of all the posts so I just need to tap them in or out to level things back up. Well drained gravel underneath so frost heave has never really been an issue. My spruce posts are all back under the cabin so they never get wet. Not the system I'm using on my house, but hey, it's worked since about 1996 so who's complaining.
