Subduction Processes Along Latin America Subduction Zones 

Subduction zones along Latin America, including those in Mexico, Central America, Caribe and South America, present a dynamic and complex diversity of Earth processes that have important effects on permanent and elastic deformation. Both in the strike and dip directions there is a marked segmentation with a wide variety of seismic and aseismic slip behavior at the plate interface and different deformation styles in the down-going and overriding plates. In addition to megathrust earthquakes, intermediate depth earthquakes and shallow backarc earthquakes are often very damaging and less well studied. Furthermore, recent years have seen an increase in onshore/offshore experiments tackling issues such as fluid content and interaction between seismic and aseismic slip. Likewise, improvements in seismic imaging and earthquake sources studies have led to a wealth of new knowledge related to convergent margin processes including both flat and normal slab subduction.   
 
In this session, we invite contributions studying the variety of subduction processes that take place in these subduction zones and their effects on permanent and elastic deformation along the margin. We welcome both theoretical, observational and modeling studies, including studies using passive and active seismology and geodesy.
