SeisComPROGLOBAL EARTHQUAKE MONITORING PROCESSING ANALYSIS
SeisComPro provides gempa's extension modulesto SeisComP for fulfilling the requirements of anenhanced real-time analysis of natural localearthquakes and for induced microseismicity.The SeisComPro modules are especially tailored tomonitoring high-rate seismicity at a wide range ofmagnitudes during earthquake swarms, mining orvolcano activity, geothermal energy production orextraction of crude oil or natural gas.
SeisComPro in a nutshell• ccloc detects microseismicity and classifies
earthquakes, explosions or blasts by cross-correlating waveforms with master templates• scanloc clusters and associates phase picks
ensuring that earthquake monitoring in high-rateseismicity areas delivers reliable hypocentres• sceval evaluates detections to identify fakes•GAPS allows earthquake analysis from anywhere•Recommended extensions: npeval, scqceval

SeisComPro: Software Extensionsand Web Applications for SeisComP
ccloc detects earthquakes and other seismicevents at very low to large magnitudes bymatching waveform templates from knownmaster events to real-time or archived data.Monitoring applications:•High-rate natural seismicity including earhquake
swarms•Micro-seismicity• Induced seismicity at geothermal power plants,
in mines or near oil and gas production wells•Nuclear explosions•Discrimination of earthquakes from other
seismic sources such as explosions
cclocCross-correlation detection with templates

GAPS is an interactive Web module perfectlycomplementing a locally installed SeisComP. Itprovides remote access to earthquake and sensorinformation and interactive processing fromanywhere through a Web browser. GAP simplifiesthe fast supply of information to stakeholders andto the public. GAP's 4 Web apps provide access to:• Earthquake activity in customized source
regions and magnitudes: EQView• Network state and activity: StationView• Real-time seismogram plots: TraceView• Interactive seismic analysis: OriginLocatorViewVisit: https://demo.gempa.de/gaps/.
scanloc is a clustering and association tool todetect and to locate local to regional earthquakesusing the cluster search algorithm DBSCAN. Thecluster search in scanloc identifies phase picksfrom a cloud of possible picks reliably associatingthem to earthquakes. It also associates additionallyincoming P- and S-phases to already existinginternal or external hypocentre solutions.In high-seismcity areas scanloc ensures reliabilityof earthquake hypocentres at a wide range ofmagnitudes. It is just perfect for monitoring localearthquakes, geothermal sites, mines orcarbonhydrate production.
sceval evaluates origins received from theSeisComP messaging system.Due to noisy data or unfavourable coincidences ofautomatic detections of seismic phases fromdifferent earthquakes or picks at wrong timesearthquake locations may be unreasonable oreven fake events. Such outliers are tagged asrejected by sceval and prevented from beingmistaken as a real earthquake. Real seiscmicevents are recognised and confirmed. In this way,operators and stakeholders are provided with thecorrect information on earthquakes avoidingunnecessary work load or excitation.
