Consultation concerning problems related to geo-electromagnetism; consultation concerning problems related to seismology and seismic risk.
Deterministic and statistical earthquake hazard assessment.
Geodetic research, global (Earth tides, resent tectonic movements) and local geodynamic (local tectonic movements in surroundings of fault, dangers objects (dams, nuclear power plants, landslides, etc.)) measurements by continuously recording extensometers, borehole tiltmeters and geodetic (GPS, EDM, precise levelling) measuring methods, gravitational measurements; Study of the connection between ground and object movements; Investigation of movements and deformations of dangerous industrial objects (dams, nuclear power stations, bridges, etc.); Development of instruments, laboratory and in-situ calibration of geodynamic and geodetic instruments. Investigation of the variations of the Earth's electromagnetic field; Deep and near-surface field geophysical research; Earthquake observations, processing and interpretation of the recorded data: Earthquake seismograms and their processing; Geophysical, geological and environmental interpretation of seismological observations; Geodynamic, earth structure and environment protection research.
Equipments and instruments to monitor various variations of the Earth's electromagnetic field, especially to investigate the long-term changes of geoelectromagnetic activity and parameters, with the following elements: 1. Széchenyi István Geophysical Observatory 2. field electromagnetic geophysical instruments 3. numerical and analogue modelling devices 4. observatory data bases.
The RI consists of the Sopronbánfalva Geodynamical Observatory, the Laboratory for Instrument Calibration, Computer Centre of the Geodetic and Geophysical Research Institute (GGRI) as well as from the instruments necessary for global and local geodynamic and geodetic measurements. The Sopronbánfalva Geodynamical Observatory in co-operation with other observatories provides data for study of the inner structure of the Earth and for the investigation of the tectonic movements in the Pannonian Basin. The Laboratory for Instrument Calibration possesses equipments and instruments for investigation and calibration of geodetic instruments. In addition the instruments of the KI provide data for geodetic and environmental basic researches. The Computer Centre supports the solution of the data processing tasks and provides direct connection with the partners of the KI.
The Hungarian Seismological Network (HSN) consists of six broadband stations: Budapest, Sopron, Becsehely, Tarpa, Piszkéstető, Mórágy, which are equipped with broadband seismometers, 24 bit digitizers, time signal receivers, industrial computers. Records of the stations are collected by the Budapest Seismological Observatory connected on-line to the additional short periodic stations and with foreign stations. Data centre with the use of recorded seismograms determines the magnitudes, geographical coordinates and focal depths of earthquakes, forwards data of the Hungarian stations to collaborative foreign institutions. The HSN guarantees for the Seismological Department of GGRI the necessary for its research work observed data and makes possible the participation in international scientific data exchange. An expectation to the Seismological Department is the immediate and accurate information of the public and the governmental institutions. in connection with earthquakes.
