Documenting the performance of unreinforced masonry buildings and buildings retrofit under a mandatory unreinforced masonry retrofit ordinance passed in 1989 and a repair and retrofit ordinance passed after the 1992 earthquakes will be the focus of two San Francisco engineers who will travel to Eureka and Ferndale on behalf of EERI. Bret Lizundia, a principal at Rutherford & Chekene, and David Bonowitz, a consulting San Francisco structural engineer, are traveling on Thursday to Humboldt County. Their observations and photos will be posted in the next few days on EERI's website. They will also be coordinating with GEER investigators, who have been in the field documenting ground displacement, and with Ken Luttrell, who is representing SEAOC's new Earthquake Performance Evaluation Program. The presence of several strong motion instruments provides a good opportunity to gather data on building performance at various acceleration levels. Check the virtual clearinghouse on EERI's website in the next few days for updates! Visit the Earthquake Clearinghouse Website here
