The Ecuadorian forearc is a complex region of accreted terranes with a history of largemegathrust earthquakes. Most recently, aMw7.8 megathrust earthquake ruptured the plateboundary offshore of Pedernales, Ecuador on 16 April 2016. Following this event, an inter-national collaboration arranged by the Instituto Geofisico at the...

The Ecuadorian convergent margin has experienced many large mega-thrust earthquakes in the past century, beginning with a 1906 event that propagated along as much as 500 km of the plate interface. Many subsections of the 1906 rupture area have subsequently produced Mw ≥ 7.7 events, culminating in the 16 April 2016, Mw 7.8 Pedernales earthquake....

On April 16th 2016 a Mw 7.8 earthquake ruptured the central coastal segment of the Ecuadorian subduction zone. Shortly after the earthquake, the Instituto Geofisico de la Escuela Politecnica Nacional of Ecuador, together with several international institutions deployed a dense, temporary seismic network to accurately categorize the post-seismic...

Megathrust ruptures and the ensuing postseismic deformation cause stress changes that may induce seismicity on upper plate crustal faults far from the coseismic rupture area. In this study, we analyze seismic swarms that occurred in the north Ecuador area of Esmeraldas, beginning two months after the 2016 Mw7.8 Pedernales, Ecuador megathrust...

Repeating earthquakes are earthquakes that repeatedly break a single, time-invariant fault patch. They are generally associated with aseismic slip, which is thought to load asperities, leading to repeated rupture. Repeating earthquakes are therefore useful tools to study aseismic slip and fault mechanics, with possible applications to...

The study of repeating earthquakes can provide us with a deeper understanding of the interaction between seismic and aseismic slip. Repeating earthquakes are the result of repeated loading and failure of single fault asperities, likely driven by surrounding aseismic slip. As such, they are especially useful in the study of transient or stable...
