"This is the preliminary solution obtained by Project CAP (Central and Southern Andes GPS Project) for the coseismic displacement field associated with the recent M 8.8 Maule earthquake in south-central Chile. Peak measured displacement is 3.04 m near the city of Concepcion, Chile. Significant displacements are evident as far east as Buenos Aires, Argentina (2-4 cm) and as far north as the Chilean border with Peru."
