2015 COSMOS Technical Session

Current Ground Motion Design Value Maps—Issues and Proposed Solutions

November 13, 2015
8:30 AM—6:00 PM
Crowne Plaza Hotel San Francisco Airport
Burlingame, California

The Consortium of Organizations for Strong-Motion Observation Systems (COSMOS) held its Annual Meeting and Technical Session at the Crowne Plaza Hotel San Francisco Airport located in Burlingame, California, on Friday, November 13th. This year's Technical Session was again co-sponsored by the Pacific Earthquake Engineering Center and the California Geological Survey.
