  • Unravelling the excitation ... Unravelling the excitation mechanism of very long-period (VLP) tremors in the Gulf of Guinea: evidence for vibrations of thin surface crustal plates
    Xia, Yingjie; Feng, Xuping; Chen, Xiaofei Geophysical journal international, 03/2024, Volume: 237, Issue: 2
    Journal Article
    Peer reviewed
    Open access

    SUMMARY The Gulf of Guinea exhibits a continuous emission of narrow-band and long-period signals (16, 26 and 27 s) on teleseismic records, yet the underlying excitation mechanism remains unclear. ...

  • Cascading foreshocks, after... Cascading foreshocks, aftershocks and earthquake swarms in a discrete fault network
    Im, Kyungjae; Avouac, Jean-Philippe Geophysical journal international, 10/2023, Volume: 235, Issue: 1
    Journal Article
    Peer reviewed
    Open access

    SUMMARY Earthquakes come in clusters formed of mostly aftershock sequences, swarms and occasional foreshock sequences. This clustering is thought to result either from stress transfer among faults, a ...

  • Uncertainty quantification ... Uncertainty quantification in time-lapse seismic imaging: a full-waveform approach
    Kotsi, M; Malcolm, A; Ely, G Geophysical journal international, 08/2020, Volume: 222, Issue: 2
    Journal Article
    Peer reviewed

    SUMMARY Time-lapse seismic monitoring using full-wavefield methods aims to accurately and robustly image rock and fluid changes within a reservoir. These changes are typically small and localized. ...

  • Slipping the Shumagin Gap: ... Slipping the Shumagin Gap: A Kinematic Coseismic and Early Afterslip Model of the Mw 7.8 Simeonof Island, Alaska, Earthquake
    Crowell, Brendan W.; Melgar, Diego Geophysical research letters, 16 October 2020, Volume: 47, Issue: 19
    Journal Article
    Peer reviewed
    Open access

    In July 2020, a Mw 7.8 earthquake initiated directly to the east of Simeonof Island offshore of the Alaska Peninsula. The earthquake ruptured the eastern part of the Shumagin Gap, a region devoid of ...

  • Comparison between alarm-ba... Comparison between alarm-based and probability-based earthquake forecasting methods
    Biondini, Emanuele; Gasperini, Paolo Geophysical journal international, 11/2023, Volume: 235, Issue: 2
    Journal Article
    Peer reviewed
    Open access

    SUMMARY In a recent work, we applied the every earthquake a precursor according to scale (EEPAS) probabilistic model to the pseudo-prospective forecasting of shallow earthquakes with magnitude $M\ ...

  • Propagation of Slow Slip Le... Propagation of Slow Slip Leading Up to the 2011 Mw 9.0 Tohoku-Oki Earthquake
    KATO, Aitaro; OBARA, Kazushige; IGARASHI, Toshihiro ... Science (American Association for the Advancement of Science), 02/2012, Volume: 335, Issue: 6069
    Journal Article
    Peer reviewed

    Recordings by Japan's dense seismic network in the days and weeks before the 2011 Mw 9.0 Tohoku-Oki earthquake provide an opportunity to interrogate what caused the dynamic rupture of one of the ...

  • On the role of density and ... On the role of density and attenuation in three-dimensional multiparameter viscoacoustic VTI frequency-domain FWI: an OBC case study from the North Sea
    Operto, S; Miniussi, A Geophysical journal international, 06/2018, Volume: 213, Issue: 3
    Journal Article
    Peer reviewed
    Open access

    3-D frequency-domain full waveform inversion (FWI) is applied on North Sea wide-azimuth ocean-bottom cable data at low frequencies (≤10 Hz) to jointly update vertical wave speed, density and quality ...

  • Distributed Global Debris T... Distributed Global Debris Thickness Estimates Reveal Debris Significantly Impacts Glacier Mass Balance
    Rounce, D. R.; Hock, R.; McNabb, R. W. ... Geophysical research letters, 28 April 2021, Volume: 48, Issue: 8
    Journal Article
    Peer reviewed
    Open access

    Supraglacial debris affects glacier mass balance as a thin layer enhances surface melting, while a thick layer reduces it. While many glaciers are debris‐covered, global glacier models do not account ...
