The last decade has seen a series of devastating earthquakes strike major population centers. The recent Izmit event on the Anatolian fault was by far the largest, most destructive, and costly in terms of human lives. Strong similarities between the Anatolian and San Andreas fault systems make this an event of particular interest. Details of the surface rupture and the relationship of damage to near-surface geology will be presented. Hear first-hand accounts of this tragic urban earthquake from scientists who arrived just days after the event to document its effects. (Note: There are no abstracts for this late-breaking session on the GSA web site.)

"GEOLOGIC HAZARD MAPPING: THE STATE OF THE ART" (T28)
CCC C101-103 Tuesday, October 26, 8:00 a.m. to 12:00 p.m.
Natural geologic processes become "hazards" in the presence of humans. New methods for mapping areas susceptible to floods, earthquakes, landslides, tsunamis, expansive soils, and liquefaction will be presented in this session.

CLIMATE

PARDEE KEYNOTE SYMPOSIUM: "GLOBALLY WARM CLIMATES OF THE EARLY CENOZOIC: EVIDENCE, CAUSES, AND BIOTIC CONSEQUENCES" (K006)
CCC Ballroom 4, Monday, October 25, 1:30 p.m.-5:30 p.m.
Earth's most recent occurrence of greenhouse conditions was in the early Cenozoic. This record lends insight to the greenhouse period we're now entering. Specific topics include the search for causal mechanisms of climate change and impacts on organisms and ecosystems. (Note: The cycle of "icehouse/greenhouse" regimes is addressed in Session T40, "The Tropics Compared: Icehouse and Greenhouse States.")
