“Our operating assumption is that everything west of Interstate 5 will be toast.”
In the Pacific Northwest, everything west of Interstate 5 covers some hundred and forty thousand square miles, including Seattle, Tacoma, Portland, Eugene, Salem (the capital city of Oregon), Olympia (the capital of Washington), and some seven million people. When the next full-margin rupture happens, that region will suffer the worst natural disaster in the history of North America. — newyorker.com
This relatively low-tech method is among a battery of tests that materials scientists are using to determine why several anchor rods securing the newest portion of the San Francisco Bay Bridge, the region’s busiest, failed their earthquake inspections. The first alarms sounded in 2013, when seismic tests found 32 faulty rods. They’d been sitting in a large pool of water, corroding. — wired.com
A vibration control device to dramatically reduce shaking caused by long-period earthquake ground motion — a phenomenon in which major earthquakes shake skyscrapers slowly but severely — was shown to the media on Monday after being installed in a 55-story building in central Tokyo. [...]
The companies said it is the nation’s first rooftop vibration control device against earthquakes. — the-japan-news.com
California’s state geologist has concluded that an active earthquake fault is underneath a massive proposed skyscraper project in Hollywood, setting the stage for a huge battle at City Hall over growth and seismic safety. — latimes.com
Stand your ground, the U.S. debut of the "Considering the Quake: Seismic Design on the Edge" exhibition will be on Feb. 13, 2014 at the AIA's Center for Architecture in New York.
Based on resilient-design research gathered by the exhibition's curators Professor Ghyslaine McClure and Dr. Effie Bouras, it highlights not only the artistic aspect of seismic design, but also its more hidden — and crucial — scientific side. — bustler.net
