The 1998 SCEC Annual meeting was held October 17-20 at the Riviera Resort and Racquet Club in Palm Springs, California, site of our 1996 meeting. The agenda for the meeting is below. Tom Henyey, Dave Jackson, Jill Andrews, Tom Rockwell, Leon Knopoff, and Ralph Archuleta assisted with the planning.
Meeting highlights:
1. An education and outreach workshop on October 17th hosted by Jill Andrews.
2. Jim Brune led an informal field trip to some spectacular precarious rocks about 15 km south of Banning (also about 15 south of the Banning Fault). A picture of one of these rocks was shown in Brune (1996), Figure 2m. Results on age dating and additional discussion were reported by Brune et al. (1997, abstracts of the 1997 SCEC Annual Meeting). The pedestal of the rock yielded a cosmogenic age date of greater than 13 ka (Bell et al., Dating Precariously Balanced Rocks in Seismically Active Parts of California and Nevada, GEOL., v. 26, no. 6, p. 495-498), and thus the rocks have apparently survived many large earthquakes on the nearby Banning and Mission Creek strands of the San Andreas Fault, thus providing constraints on the ground motion from large earthquakes. Field tests have indicated that ground motion of about 0.25 g would topple these rocks. The Frankel et al. (1996) hazard maps for 2% probability in 50 years give accelerations about twice as high, an inconsistency of the type UNR is attempting to resolve in a current SCEC grant. One large boulder can easily be rocked by hand. Brune (1996), Bull. SSA, 86, 1A, p. 43.
3. Sally McGill invited all SCEC members to visit two trenches on the San Andreas fault on your way to or from the SCEC meeting. The trenches were located near Plunge Creek in Highland (the suburb immediately east of San Bernardino), and are about a 10-minute drive north of Interstate 10 (see directions below). One of the trenches reveals two faulting events. The older event occurred shortly after A.D. 1235-1410, and the younger event occurred between A.D. 1439 and A.D. 1643. So far, we have found no evidence for younger ruptures at the Plunge Creek site that could correspond to the A.D. 1812 and A.D. 1700 events at Pitman Canyon and Wrightwood. A second trench opened on another young alluvial fan at this site was an attempt to determine whether or not more recent earthquakes have occurred at this site.
4. More time for posters on SCEC sponsored research.
5. As we began our ninth and final full year of SCEC funding, there were talks to highlight the achievements of each group and what needs to be done to complete work by 1/31/02, SCEC's sunset date. These talks set the stage for the group meetings.
6. SCEC and SCIGN Advisory Council Meetings.
8. A meeting of the GEM investigators.
9. A joint SCEC/PEER workshop on Tuesday, the 20th.
