Journal Article
Melnick, D., Hillemann, C., Jara-Muñoz, J., Garrett, E., Cortés-Aranda, J., Molina, D., …Strecker, M. R. (2019). Hidden Holocene slip along the coastal El Yolki fault in Central Chile and its possible link with megathrust earthquakes. Journal of Geophysical Research. Solid Earth, 124(7), 7280-7302. https://doi.org/10.1029/2018jb017188

Megathrust earthquakes are commonly accompanied by increased upper‐plate seismicity and occasionally triggered fault slip. In Chile, crustal faults slipped during and after the 2010 Maule (M8.8) earthquake. We studied the El Yolki fault (EYOF), a tra...

Assessments of megathrust earthquake rupture patterns provide fundamental insights into the processes that control the seismic cycle along subduction zones. When large earthquakes occur in regions with sparse geodetic networks, as was the case for th...
