Abstract

Mind the seismic gap Analysis of seismic data and Global Positioning System (GPS) observations from the region around the site of the recent magnitude-8.8 Maule earthquake in Chile have been combined with modelling of the Andean subduction zone to build up a detailed image of the event. The earthquake occurred at a 'seismic gap', part of the fault that has not experienced a major earthquake since 1835, and it seems to have released most of the stress accumulated since that time. The observations suggest that coseismic slip heterogeneity at the scale of single asperities, and therefore the seismic potential of future great earthquakes, might be anticipated by geodetic observations.
