Following undergraduate studies at the University of Bremen (Germany), Thessa Tormann obtained her MSc in Geophysics at Victoria University of Wellington (New Zealand). In 2011, she received her PhD from ETH Zurich for her thesis "b-values as stress-meters in the earth's crust". She is part of the Statistical Seismology group at the Swiss Seismological Service.
Thessa Tormann's main research interest is the statistical analysis of seismicity on different scales, from subduction zones to local microseismicity, with the target of understanding the physical processes behind revealed patterns. A strong focus is the investigation of size distributions of natural or induced microseismicity and what those can reveal about the stress conditions at a monitored site, e.g. a potential reservoir. Such understanding can help to improve the assessment of associated seismic hazard.
