...Ali Tolga Şen; Simone Cesca; Dietrich Lange; Torsten Dahm; Frederik Tilmann; Sebastian Heimann Abstract The very shallow part of subduction megathrusts occasionally hosts tsunami earthquakes, with unusually slow rupture propagation. The aftershock sequence of the 2010 M w 8.8 Maule earthquake...

... of greatest slip during the 2010 M w 8.8 Maule earthquake (offshore Chile) to complement a natural-source seismic experiment designed to monitor the post-earthquake response of the outer accretionary prism. We describe the MCS data and discuss the implications for the response of the accretionary prism during...

... earthquakes greater than M w  8.3. Analyses of the strong‐motion recordings of the 2010 M w  8.8 Maule, Chile, and the 2011 M w  9.0 Tohoku, Japan, earthquakes provide important insights on the rupture process of great earthquakes that will help improve predictions of strong ground shaking for future...

...-strike variation of splay fault activation. The Constitutión-Concepción segment in central Chile was considered to be a mature seismic gap showing little seismic activity on the megathrust since the last great earthquake in 1835. On 27 February 2010, this segment ruptured in the M w 8.8 Maule...

...Saburoh Midorikawa; Hiroaki Yamanaka; Kosuke Chimoto; Rafael Riddell; Hiroyuki Miura; Koichiro Saguchi Abstract In the 2010 Maule, Chile, earthquake ( M w 8.8), many high‐rise buildings in downtown Concepción (CONC) sustained severe damage. The accelerogram observed at CONC had large amplitudes...

..., to provide an unparalleled view of the offshore portion of the southern Chilean forearc. Melnick et al. (2012) recently postulated the activity of a splay thrust fault, the Santa María Fault System (SMFS), during the 2010 Maule earthquake. This work is timely given current interest in the role of splay...

... along the Santa María Fault Zone (SMFZ) during the 2010 Maule (Chile) earthquake: the spatial relation between megathrust slip and the SMFZ, and the relationship between coseismic and longer-term deformation patterns. The upper-plate strain regime leading to reactivation of splay faults during...

...Eric Kiser; Miaki Ishii Abstract A backprojection method is applied to the 27 February 2010 M w 8.8 and 25 March 2012 M w 7.1 Maule, Chile, earthquakes using high‐frequency (0.8–2 Hz) USArray data. During the 2010 event, highest energy release occurred north of the epicenter, with two subevents...

... ruptures and coastal uplift at Isla Santa María in south-central Chile (37°S) caused by the 27 February 2010 Maule earthquake ( M w 8.8). During the earthquake, the island was tilted parallel to the margin, and normal faults ruptured the surface and adjacent ocean bottom. We associate tilt and crestal...

...Emile A. Okal; Sutatcha Hongsresawat; Seth Stein Abstract We present a comprehensive study of the Earth’s gravest spheroidal modes excited by the Maule, Chile, earthquake of 27 February 2010, using uninterrupted time series extending over a minimum of 19 and a maximum of 93 days. For each of 101...

... the QCN RAMP following the 27 February 2010 M 8.8 Maule, Chile earthquake. Once the location has been estimated, the magnitude is computed using an empirical magnitude distance relationship with the acceleration vector magnitude, |a|, similar to the method of Wu et al. ( 2003 ) and Cua and Heaton...

...Zhigang Peng; Hector Gonzalez‐Huizar; Kevin Chao; Chastity Aiken; Bladimir Moreno; Gregory Armstrong Abstract We provide additional evidence of tectonic tremor in Cuba triggered by the 2010 M w 8.8 Maule, Chile, and the 2011 M w 9.0 Tohoku‐Oki, Japan, earthquakes. The high‐frequency tremor signals...

...Felipe Aron; José Cembrano; Felipe Astudillo; Richard W. Allmendinger; Gloria Arancibia Abstract We present new field structural data from the Chilean Coastal Cordillera located above the northern and central parts of the interplate contact ruptured by the A.D. 2010 M w 8.8 Maule earthquake...

..., including simultaneously solving for global velocity structure. To illustrate the technique, we apply it to the Maule region of Chile, where an M w 8.8 earthquake occurred in 2010. * Now at Spectraseis Inc., 1899 Wynkoop Street, Suite 350, Denver, Colorado 80202. 13 May 2013...
