Our research

We investigate tectonically active regions around the world using a variety of seismological methods, and we combine our results with constraints from other disciplines. Recent research topics include:

  • Subduction zone processes as highlighted by seismicity and seismic velocities
  • Faulting and seismic hazard in continental collision zones
  • Effects of fluid and melt migration on volcanic activity in subduction environments
  • Relation between intraslab earthquakes and bending and unbending stresses

Ongoing projects:

 

OpenEEW, development of an open-source earthquake early warning system (Collaborator: Václav Kuna)

MILESTONE ‘Microseismicity Illuminates Subduction Zone structure’ ERC Starting Grant (PI: Christian Sippl, 2021-2026)

CAS-ANID Mobility Plus project ‘Deep learning seismology applied to the Chilean subduction zone’ (Collaborator: Christian Sippl, 03/2023-03/2024)

 

Finished projects:

PRECURSOR, investigating precursory and coseismic processes on the Chilean megathrust supported by the Chilean Science Foundation (Collaborator: Christian Sippl, 2020-2022)
