Seismic Data Acquisition
|
 |
|
| Seismic data acquisition consists of gathering and recording of continuous seismic signals from seismic stations. Process of automatic acquisition, detection, processing and dissemination of seismic data at Observatory's acquisition center is performed on three parallel acquisition systems: DASP (B. Glavatovic, MSO, Montenegro), SeisComP3 (GFZ, Potsdam, Germany) and SmartGeoHub (Geotech Instruments, Dallas, TX).
Acquisition of analogue signals is executed on DASP acquisition system, developed by director of Montenegro Seismological Observatory Prof. Branislav Glavatovic and collaborators. This system is constituted in the beginning of seismic signal acquisition era on PC computers in the World and it has been in operation more than 20 years.
Digital seismic signal acquisition is supported by two acquisition platforms (SeisComP3 and SMARTGeoHub servers), for fully automated earthquake data processing and analyzing of earthquake information, along with simultaneous application of dozens of programs for those purposes. Average time of automatic system reaction on earthquake occurrence on the Montenegro territory and its surroundings, with processing and distribution of earthquake data via Internet and SMS messages is three minutes. |

Digital seismic data acquisition with automatic earthquake data processing and dissemination |

After earthquake occurrence, off-line data processing is done on special software developed in Observatory, creating final parameters of earthquake, on the Montenegro territory, western Balkan and the World.
Digital processing of seismological data, using computer technique, has been started in Observatory from the beginning of applying computer methods in seismology, more than 30 years. During that period of time, original methods of analysis and processing of seismic data are developed in Observatory, which results with comprehensive collection of home-made developed programs.
Seismological database, placed on special data storage (picture on the left) with 6TB capacity, includes: bulletins (from 1979), catalogues (from 1970), digital seismograms of earthquakes registered with Montenegrin seismic network (from 1990), accelerograms (from 1976), continuous seismograms in miniseed format (from 2008) and continuous seismograms in suds format (from 2009). |
