SeisComP3 locator for (very) local earthquakes


scanloc is designed to monitor local and micro seismicity within small networks with 5 to 20 stations and station distances in the range of kilometers to tenth of kilometers.

scanloc is using a cluster search algorithm to associate detections to one or many potential earthquake sources. While the cluster search itself is based on P-phases only, in a second step S-phases are also associated and used for locating the earthquake.

scanloc has proven its usefulness for example by detecting between 200-300 earthquakes a day with magnitudes ranging from M1 to M4 with only a few false detections per day in the CX network (Chile) with station distances of about 50-70 kilometers.
