The muma group focuses on methods to improve the imaging of seismicity patterns in natural and induced microearthquake sequences. Such patterns express the underlying earthquake-physical or external forcing mechanisms that drive the seismicity. Earthquake-physical mechanisms include all processes involved in the earthquake nucleation process in and near the seismic source. It can range from precursory aseismic slip to cascading foreshock interactions. In contrast, external forcing mechanisms incorporate all mechanisms impacting seismicity from outside the seismic source, ranging from earthquake-earthquake interactions, via seasonal hydrological changes, to anthropogenic impacts from geotechnical operations. High-resolution monitoring of seismicity patterns provides the most direct geophysical tool for imaging these processes outside of laboratory settings.
The muma group is led by Dr. Toni Kraft and works to improve the precision and reliability of Switzerland’s national earthquake catalogue through advanced data processing techniques. The group also takes a leading role in monitoring seismic activity related to industrial subsurface operations, such as geothermal energy projects in the framework of the GEOBEST project or tunnelling. Their research provides valuable insights into both natural and induced seismicity, contributing to safe industrial practices and improved public safety.
