On September 18th, 2022, at 2:44 pm local time, a moment magnitude 6.9 earthquake struck 42.7 km north of Taitung City, Taiwan. The earthquake followed a magnitude 6.5 earthquake in the same area the previous day. The M6.9 earthquake caused both geotechnical failures and damage to infrastructure, mainly bridges, railroads, and highways. Damage to buildings was primarily concentrated on older non-ductile structures, as well as non-structural component damage. At least one building collapsed and hundreds more suffered some damage. The earthquake resulted in at least one death and 171 injuries.
The earthquake highlighted the vulnerabilities of older non-ductile concrete buildings in seismic regions, concrete bridges, and non-structural building components during an earthquake. This webinar will provide an overview of the event, including the earthquake seismology, emergency management, and geotechnical and structural engineering impacts.
