Seismic Hazards along the Chilean Subduction Zone Inferred from 25 Years of GPS
I'll be reviewing GPS work in Chile since Bevis and Klotz groups in the early 1990s', explain tectonics setting and the question of partioning (ie. Andean sliver), detail the GPS newtorks we installed and survey since 2002, show coupling maps they provide and their correlation with seismicity, revesit seismic hazard of several known gaps, then focus on the history of large subduction Eq in chile, explain how and why current day coupling determined by GPS is quite relevant to asses futur Eq characteristics, revisit the hazard posed in North Chile (explain why I think next Eq there is not to be expected soon) and on the opposite suggest other mature gaps for candidates.
