For the General scopes see introduction to symposium JSS004. Paleoseismology is now a wellestablished
discipline whose major goal is the identification and dating of past earthquakes in the
geological record. It provides the fundamental data for developing an understanding of the behavior of
seismogenic faults in time and space and the primary recurrence information for seismic hazard
assessment. Paleoseismlogy has evolved during the past 30 years and is now practiced worldwide. As
the field moves into the 21st century there is recognition of the need to: develop longer earthquake
chronologies, reduce uncertainties in recurrence times, and develop better knowledge of earthquake
recurrence on sources that do not not easily lend themselves to traditional paleoseismic analysis
(trenching). We invite contributions on topics that include NEW: -statistical analyses of paleoseimic
recurrence data, particularly for correlating the occurrence of past events along faults ; -approaches to
identify paleoearthquakes on blind or remote (ie, subduction zone) earthquake sources and in
logistically difficult settings such as urban environments; -technologies that increase the length of the
paleoseismic record and paleoearthquake chronologies at investigation sites on major faults; -dating
techniques of paleoearthquakes; -approaches to quantify slip in paleoearthquakes for better estimates
of paleo-earthquake magnitudes
