Transform Plate Boundaries: Mechanics and Hazards Posters

Submit an Abstract to this Session



Session ID#: 26428

Session Description:
Transform plate boundaries offer a window into the mechanical deformation of lithosphere absent of external mantle processes (corner flow, upwelling). Continental transforms also present significant hazards due to their proximity to population centers. A variety of deformation styles occur at transform plate boundaries, particularly at fault stepovers, endpoints, and in oblique zones. Recent ruptures of transform faults including the Kekerengu Fault of New Zealand and the Queen Charlotte Fault of western North America highlight the need for improved understanding of the mechanics and deformation processes associated with transform systems. We seek contributions highlighting new results from the recent Kaikoura earthquake and studies of the Queen Charlotte Fault, the San Andreas Fault, the North Anatolian Fault, and the Alpine Fault. We emphasize the importance of multi- and cross-disciplinary approaches to study transform systems and welcome broad contributions, especially research involving earthquake seismology, paleoseismology, marine geology and geophysics, tectonic geomorphology, and geodesy.
