2016 SCEC Ventura Special Fault Study Area Workshop

Applications Due: August 8, 2016
Participants: 60 maximum

Date: September 10, 2016
Time: 9:00am-5:00pm
Location: Hilton Palm Springs Resort

SCEC Award: 16027

First Workshop: August 15, 2013

CONVENERS: Scott Marshall, James Dolan, Thomas Rockwell, and John Shaw

OVERVIEW: With the Ventura Special Fault Study Area winding down in the next year, the time has come to bring together the most up to date and significant results and attempt to form a consensus view of the Ventura fault system and its associated hazards. To this end, we will host a 1-day workshop on the Saturday before the 2016 SCEC Annual Meeting in Palm Springs, CA. Workshop presentations will focus on recent findings for the Ventura SFSA in the areas of near-surface and offshore geophysics, crustal structure, geodesy, fault modeling, paleoseismology, tectonic geomorphology, seismology, and dynamic rupture and tsunami modeling. Each topical session will have invited oral presentations followed by significant time for constructive discussions.
