SSA 2001 Annual Meeting

Planned Field Trips

Great Faults of the Bay Area: A Ride through the Past to See the Future
Field trip leaders: David Schwartz, Jim Lienkaemper (USGS, Menlo Park), William Lettis, Keith Kelson, Jeff Unruh (William Lettis and Associates), Gordon Seitz (LLNL), and Thomas Sawyer (Piedmont Geosciences)
Saturday, 21 April 2001, 8:00 a.m.-6:00 p.m. (return approximate). Fee $35.

Great Shakes from the East Bay: The faults east of San Francisco Bay carry almost half of the Pacific-North American plate boundary slip through the Bay Area. This field trip will provide the opportunity to visit these faults before they produce their next big earthquakes! We'll stop at locations on the southern Hayward, northern Calaveras, and Greenville strike-slip faults, and on the hanging wall of the Mt. Diablo blind thrust atop the summit of Mt. Diablo. We will discuss and debate recurrence, fault behavior, seismicity, tectonics, and earthquakes hazards of this rapidly developing region. And of course we'll test the effect of active faulting on grapes with a sampling of Livermore Valley's earthquake wines. Boxed lunches will be provided. Wear comfortable shoes; hats are recommended. The bus will pick up participants in front of the Cathedral Hill Hotel at 8:00 a.m. and will return them to the hotel at approximately 6:00 p.m.

Strengthening Our Civic Heritage: Recent San Francisco Retrofits
Field trip leader: Eric Elsesser, Forell/Elsesser Engineers, Inc. of San Francisco
Saturday, 21 April 2001, 9:00 a.m.-1:00 p.m. (approximate). Fee $10.

This half-day field trip will start with a slide presentation describing the retrofit process and use of base isolators at San Francisco City Hall. Trip participants will then go on site to view the base isolators and the retrofit process currently taking place at the Asian Art Museum. Finally, participants will see the final product of a retrofit in an inspection of San Francisco City Hall (see Special Events for more information about City Hall). Participants should meet at 9:00 a.m. inside the Polk Street entrance to City Hall, an eight-block walk from the Cathedral Hill Hotel.
