Time-reverse imaging has become an efficient tool to detect the origin of passively acquired seismic tremor signals. Practical experience has mainly been developed for 2D applications. Three component signals are reduced to two components and reverse propagated on the plane vertically below a station line. The data used for time-reverse imaging are the vertical and the horizontal particle displacement...
Central Switzerland shows comparatively high seismic activity by Swiss standards. Many historical earthquakes are known and several of them caused damage. The last major event dates back to 1964 and has the characteristics of an earthquake swarm. Among dozens of felt shocks were two main shocks (Mw = 5 and 5.7) that moderately damaged a limited area with hundreds of buildings suffering loss. Our aim...
