Lars Ottemöller

Lars Ottemöller is a Professor at the Department of Earth Science, University of Bergen, and leads the Norwegian National Seismic Network. He specializes in earthquake seismology, geophysics, and tectonics, with a focus on seismic network analysis, intraplate seismicity, and subduction zone processes. His work integrates seismic tomography, waveform analysis, and observational seismology to study fault systems, mantle dynamics, and environmental triggers for earthquakes.

Research interests include crustal structure analysis (e.g., Moho architecture in the Lofoten-Vesterålen margin), hydrological loading effects on seismicity (Jektvik swarm sequence), and Arctic seismology (e.g., Loki's Castle hydrothermal vent field). He supervises doctoral students like Hasbi Ash Shiddiqi and Quetzalcoatl Rodríguez-Pérez, contributing to projects like EPOS-Norway and the Bergen Arcs Seismic Experiment.

Key contributions involve developing magnitude scales (e.g., ML for the UK), improving seismic network quality (Norwegian and Turkish networks), and advancing waveform-based characterization of slab-mantle wedge earthquakes. His recent work addresses seismicity patterns in stable continental regions and the interplay between tectonic stress and hydrothermal systems in mid-ocean ridges.

He collaborates internationally, co-authoring over 80 publications and contributing to software development (SEISAN). Current projects include background seismicity monitoring for CO2 storage and Arctic seismic monitoring initiatives.
