• Ambient noise levels and detection threshold in Norway 

      Demuth, Andrea; Ottemöller, Lars; Keers, Henk (Peer reviewed; Journal article, 2016-07)
      Ambient seismic noise is caused by a number of sources in specific frequency bands. The quantification of ambient noise makes it possible to evaluate station and network performance. We evaluate noise levels in Norway from ...
    • 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 ...
    • Extending local magnitude ML to short distances 

      Luckett, Richard; Ottemöller, Lars; Butcher, Antony; Baptie, Brian (Peer reviewed; Journal article, 2019)
      Local magnitudes calculated at stations less than 10 km from earthquakes in the British Isles are up to one unit of magnitude higher than local magnitudes calculated at more distant stations. This causes a considerable ...
    • 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 ...
