Earthquakes track subduction fluids from slab source to mantle wedge sink
Halpaap, Felix; Rondenay, Stéphane; Perrin, Alexander; Goes, Saskia; Ottemöller, Lars; Austrheim, Håkon; Shaw, Robert; Eeken, Thomas (Peer reviewed; Journal article, 2019)Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly related. By combining seismic ... -
Imaging Subduction Beneath Mount St. Helens: Implications for Slab Dehydration and Magma Transport
Mann, Michael E.; Abers, Geoffrey A.; Crosbie, Kayla; Creager, Kenneth; Ulberg, Carl; Moran, Seth; Rondenay, Stéphane (Peer reviewed; Journal article, 2019)Mount St. Helens (MSH) is anomalously 35–50 km trenchward of the main Cascade arc. To elucidate the source of this anomalous forearc volcanism, the teleseismic‐scattered wavefield is used to image beneath MSH with a dense ... -
Localized crustal deformation along the central North Anatolian Fault Zone revealed by joint inversion of P-receiver functions and P-wave polarizations
Schiffer, Christian; Eken, Tuna; Rondenay, Stéphane; Taymaz, Tuncay (Peer reviewed; Journal article, 2019)The North Anatolian Fault Zone (NAFZ) is a major plate boundary that separates the Eurasian Plate to the north from the Anatolian Plate to the south and is associated with powerful damaging earthquakes. Despite numerous ... -
Multimode 3‐D Kirchhoff Migration of Receiver Functions at Continental Scale
Millet, Florian; Bodin, Thomas; Rondenay, Stéphane (Journal article; Peer reviewed, 2019)Receiver function analysis is widely used to image sharp structures in the Earth, such as the Moho or transition zone discontinuities. Standard procedures either rely on the assumption that underlying discontinuities are ... -
A reappraisal of the H–κ stacking technique: implications for global crustal structure
Ogden, CS; Bastow, Ian D; Gilligan, Amy; Rondenay, Stéphane (Journal article; Peer reviewed, 2019)H–κ stacking is used routinely to infer crustal thickness and bulk-crustal VP/VS ratio from teleseismic receiver functions. The method assumes that the largest amplitude P-to-S conversions beneath the seismograph station ... -
Seismicity, Deformation, and Metamorphism in the Western Hellenic Subduction Zone: New Constraints From Tomography
Halpaap, Felix; Rondenay, Stéphane; Ottemöller, Lars (Peer reviewed; Journal article, 2018-02-23)The Western Hellenic Subduction Zone is characterized by a transition from oceanic to continental subduction. In the southern oceanic portion of the system, abundant seismicity reaches depths of 100 km to 190 km, while the ... -
Water Migration in the Subduction Mantle Wedge: A Two-Phase Flow Approach
Wang, Hongliang; Huismans, Ritske; Rondenay, Stéphane (Journal article; Peer reviewed, 2019)Subduction zones are the main entry points of water into Earth's mantle and play an important role in the global water cycle. The progressive release of water by metamorphic dehydration induces important physical‐chemical ...
