    • 3D Local Earthquake Tomography of the Ecuadorian Margin in the Source Area of the 2016 Mw 7.8 Pedernales Earthquake 

      León‐Ríos, Sergio; Bie, Lidong; Agurto‐Detzel, Hans; Rietbrock, AndreasORCIDiD; Galve, AudreyORCIDiD; Alvarado, AlexandraORCIDiD; Beck, SusanORCIDiD; Charvis, PhilippeORCIDiD; Font, Yvonne; Hidalgo, SilvanaORCIDiD; Hoskins, MariahORCIDiD; Laigle, Mireille; Oregioni, Davide; Meltzer, AnneORCIDiD; Ruiz, MarioORCIDiD; Woollam, JackORCIDiD (Journal of Geophysical Research: Solid Earth, 2021-03-25)
      Based on manually analyzed waveforms recorded by the permanent Ecuadorian network and our large aftershock deployment installed after the Pedernales earthquake, we derive three‐dimensional Vp and Vp/Vs structures and ...
    • An Exhumation Pulse From the Nascent Franciscan Subduction Zone (California, USA) 

      Rutte, DanielORCIDiD; Garber, JoshuaORCIDiD; Kylander-Clark, AndrewORCIDiD; Renne, Paul R.ORCIDiD (Tectonics, 2020)
      We investigated a suite of metabasite blocks from serpentinite matrix and shale matrix mélanges of the California Coast Ranges. Our new data set consists of 40Ar/39Ar dates of amphibole and phengite and U-Pb dates of ...
    • Evolution of Magmatism in the New Hebrides Island Arc and in Initial Back-Arc Rifting, SW Pacific 

      Haase, K. M.ORCIDiD; Gress, M. U.ORCIDiD; Lima, S. M.; Regelous, M.; Beier, C.ORCIDiD; Romer, R. L.; Bellon, H. (Geochemistry, Geophysics, Geosystems, 2020)
      We present new geochemical and isotopic data for rock samples from two island arc volcanoes, Erromango and Vulcan Seamount, and from a 500 m thick stratigraphic profile of lava flows exposed on the SW flank of Vate Trough ...
    • Observations of Laboratory and Natural Slow Slip Events: Hikurangi Subduction Zone, New Zealand 

      Ikari, Matt J.ORCIDiD; Wallace, Laura M.ORCIDiD; Rabinowitz, Hannah S.ORCIDiD; Savage, Heather M.ORCIDiD; Hamling, Ian J.ORCIDiD; Kopf, Achim J. (Geochemistry, Geophysics, Geosystems, 2020)
      Slow slip events (SSEs) are recognized as an important component of plate boundary fault slip, and there is a need for laboratory friction data on natural samples to guide comparisons with natural SSEs. Here, we compile a ...
    • Plume-Induced Subduction Initiation: Single-Slab or Multi-Slab Subduction? 

      Baes, MarziehORCIDiD; Sobolev, StephanORCIDiD; Gerya, Taras; Brune, SaschaORCIDiD (Geochemistry, Geophysics, Geosystems, 2020)
      Initiation of subduction following the impingement of a hot buoyant mantle plume is one of the few scenarios that allow breaking the lithosphere and recycling a stagnant lid without requiring any preexisting weak zones. ...
