Recent earthquakes in Chile, 2014, Mw 8.2 Iquique, 2015, Mw 8.3 Illapel and 2016, Mw 7.6 Chiloe have put in evidence some problems with the straightforward application of ideas about seismic gaps, earthquake periodicity ...

Along a subduction zone, great megathrust earthquakes recur either after long seismic gaps lastingseveral decades to centuries or over much shorter periods lasting hours to a few years when cascadingsuccessions of earthquakes ...

The 2010 Mw = 8.8 Maule earthquake, which occurred in the subduction contact between the Nazca and the South American tectonic plates off the coast of Chile, represents an important opportunity to improve understanding of ...

We present a novel approach combining time-variable computations of b-value and afterslip to study the postseismic activity following the Mw 8.8 Maule 2010 earthquake. We subdivided the first 392 days after the mainshock ...

The characterization of a seismogenic zone associated with the rupture process that occurs during great megathrust earthquakes has been approached from different perspectives. Different studies lightened the structural ...

The recent 2011 Tohoku-oki earthquake occurred in a region where giant megathrust earthquakes were not expected. This earthquake proved the difficulty to assess seismic hazard mainly based on information from historical ...

Complexities in the rupture process during a megathrust earthquake can be attributed to the combined effect of inhomogeneous distribution of stress accumulated during the interseismic period and inho-mogeneous rheology of ...

Historical and paleoseismic records in south-central Chile indicate that giant earthquakes on the subduction megathrust - such as in AD1960 (M-w 9.5) - reoccur on average every similar to 300 yr. Based on geodetic calculations ...

Segmentation can influence the extent of earthquake rupture and event magnitude(1): large megathrust earthquakes result from total rupture of relatively continuous segments of the subduction interface(2-5). Segmentation ...
