This report is based on a year-long investigation of the earthquake impacts and covers seismology and tectonics, geotechnical impacts on buildings and infrastructures, building codes and their impact on the earthquake damage, structural impacts on buildings, nonstructural damage, performance of instrumented buildings, impacts on schools and hospitals, performance of bridges, and damage to lifelines and […]
Geotechnical Engineering Reconnaissance of the 30 November 2018 M7.0 Anchorage, Alaska Earthquake
Between the dates of December 8 through 15, 2018, the Geotechnical Extreme Events Reconnaissance Association (GEER) deployed a multi-disciplinary Phase I team comprised of seven investigators to observe and document the significant geotechnical engineering impacts and lessons learned from this event. The GEER team collaborated closely with other engineering reconnaissance efforts including those led by […]
Preliminary Observations in the Aftermath of the November 30, 2018 Anchorage, Alaska Earthquake
In the days following the November 30, 7.0M Anchorage earthquake, SOM engineering team Samantha Walker and Patrick Murren deployed to Alaska on a reconnaissance effort to chronicle building performance, view damaged buildings, and collaborate with the structural and earthquake engineering communities at large. The team spent several days in Anchorage and south-central Alaska documenting the […]
Shaking of Frontier Building in Anchorage, Alaska during the M7.0 November 30, 2018, Anchorage, Alaska Earthquake
The building was instrumented by U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking. Such data are useful in making decisions about improving the performance of this and similar buildings. See the video here: https://www.youtube.com/watch?v=BXhU5oeIgs0&feature=youtu.be
New maps and data show widespread Anchorage earthquake damage and more than 100 unsafe buildings by Anchorage Daily News
The new data, compiled in response to requests from the Anchorage Daily News, offer the first detailed look at the location and extent of the damage left by the quake. There were no fatalities and relatively minor injuries, but public and private inspections are unearthing a wide range of structural damage, including shifting earth, cracked […]
