Shaking a non-reinforced building very hard will cause it to fall down, he said. Damage from every earthquake takes on its own flavor, he said, speaking by phone Wednesday on the road to meet with officials in Wasilla.Īfter a 6.6 quake struck central Italy and caused extensive damage, Franke concluded the main cause was the type of structures and construction practices from hundreds of years ago. Called the Geotechnical Extreme Events Reconnaissance Association, or GEER, the team also includes faculty from the University of Nevada Reno, Oregon State University, North Carolina State University and the University of Alaska Anchorage.įranke personally has traveled to Japan, Central Italy and Mexico City since 2016. The chief goal is to look at what worked and what didn’t, said Kevin Franke, a civil engineering professor with Brigham Young University and the team leader. 30 quake after doing similar work around the world.

Meanwhile, Anchorage’s buildings are the subject of intense interest to both local and out-of-state engineers, as a lesson in how to build - or not.Ī national team landed in Anchorage several days ago to study the Nov. But engineers warn the extent of the damage hasn’t yet been fully realized. There are tens of thousands of buildings in the Anchorage Bowl, and officials have expressed relief the damage wasn’t more widespread. More than 180 additional structures suffered damage. More than 100 buildings in the Anchorage area, including Chugiak-Eagle River, have been declared unsafe because of structural damage caused by the earthquake. That’s a growing consensus emerging from the geotechnical community as Anchorage and Mat-Su take stock of quake damage. It’s more a problem with the ground beneath the buildings, the engineers say - and the ground failed in some surprising ways that may be rooted in the use of man-made fill rather than natural slides.

30.īut the less obvious structural damage, including cracked foundations and tilted walls, that did occur really isn’t a building problem, based on interviews with a half-dozen structural and geotechnical engineers. Officials credited strong building codes for the collapse of very few structures in the magnitude 7.0 earthquake that shook Southcentral Alaska on Nov.
30, which broke windows, caused structural damage to the walls and foundation, along with broken water pipes. Junior Patea checked on the Jesus Is Lord Church at 3rd Avenue and Post Road after a 7.0 earthquake on Nov. Updated: DecemPublished: December 13, 2018
