The magnitude 7.0 earthquake that struck southern Alaska on Nov. 30 cracked roads and collapsed highway ramps, but there were no reports of widespread catastrophic damage or collapsed buildings. Analysts say the state’s strict building codes helped structures withstand the shifting earth.

Sterling Strait, a member of the Alaska Seismic Hazards Safety Commission, noted that the state uses the International Building Code, considered the best available standard for seismic safety. It requires buildings to be designed to resist possible ground motion determined by location and earthquake histories. It also mandates structural connections — such as beams and columns — be reinforced to resist damage from shaking.
