Current rates of convergence across the central Andes : Estimates from continuous GPS observations

Crustal deformation and surface kinematics after the 2010 earthquakes in Latin America

“…The first one, called VEMOS2003 (Velocity Model of South America 2003, Drewes and Heidbach 2005), includes 48 velocities derived from a multiyear solution for the continuously observing SIRGAS reference stations (Seemüller et al 2002) and 281 velocities from several geodetic reference and geodynamic projects based on GPS campaigns , Kaniuth et al 1998, Norabuena et al 1998, Brooks et al 2003, Kendrick et al 1999, Lamb 2000, Khazaradze and Klotz 2003, Klotz et al 2001. It covers the South American area between the latitudes 45° S and 12° N. The second model, VEMOS2009 (Drewes and Heidbach 2012, Fig.…”

Structure and development of the Andean system between 36° and 39°S

“…Since 26 Ma ago, the Nazca plate was subducted beneath the South American plate at the Central and Patagonian Andean latitudes ( Figure 1) (Pardo Casas and Molnar, 1989;Somoza, 1998), dipping about 30ºE with an oblique convergence vector with respect to the trench of 79ºN at 7.9 cm/yr (Kendrick et al, 1999).…”

Rapidly Estimated Seismic Source Parameters for the 16 September 2015 Illapel, Chile M w 8.3 Earthquake

“…The toothed white curves indicate the trench position 322 L. Ye et al Pure Appl. Geophys. decades (e.g., NORABUENA et al 1998;KENDRICK et al 1999). Several early interpretations modeled GPS observations with a uniformly totally locked shallow plate boundary and a significantly deforming backarc region (e.g., KENDRICK et al 2001;KHAZARADZE and KLOTZ 2003;BROOKS 2003).…”
