Local earthquake monitoring
scanloc makes use of a cluster search algorithm to associate phase 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.
In order to provide high-quality picks from S phases, a new S picker is distributed along with scanloc. The S picker allows to identify S phases on the horizontal components or on the vertical components if the horizontals should be unavailable. A user-friendly GUI allows to tune the S picker configuration.Brochure Documentation
scanloc finds earthquakes from only few observations of P an S phases
scanloc has proven its performance for example by detecting between 200-300 earthquakes a day with magnitudes ranging from M1 to M4 with only very few false detections in the CX network (Chile) with station distances of about 50-70 kilometers. The module is also widely applied to record swarm earthquakes at short epicentreal distances or micro earthquake in geothermal environments or in oil and gas production sites.
Employ scanloc in a wide range of monitoring:
scanloc has been demonstrated, promoted and discussed with scientists and the SeisComP community at international science conferences, e.g.:
