  • Earthquake complexity and co-seismic rupture history
  • Earthquake cylce and sequence interactions

 

In my research i am interested in how earthquakes ruptures behave and how and why earthquakes develop complex ruptures in space and time.  Earthquake rupture behaves very differently in each case, sometimes propagation of the rupture occures across multiple fault planes with different geometries and sometimes it slows down/accelerates in different parts of the involved rupture area. I am interested in modelling this complex behaviour by using InSAR, GNSS and seismological data.  Often the choice of the modeled degree of complexity is however dependent on expert knowledge. Therefore i am looking for data driven ways to help us evaluate complex rupture behavior. In my Ph.D. i focus on continetal medium sized earthquakes to investigate if we can resolve their complex ruptures or if they do not exhibit such behavior. Also they are often neglected in studies but do have a significant impact on the hazard and as part of the seismic cycle.

As part of this project a code to asses the evolution of an earthquake rupture in time with a multi-array backprojection method has been developed, which is available on github: Palantiri
