The main objectives are:
- the revision of the historical part of the present national earthquake catalogue, on the basis of systematic analyses of existing archive documents – by reevaluating seismic event parameters (magnitude, depth), by finding new and reliable information on seismic events which are not reported yet, by identifying false events in the catalogue;
- the compilation of improved macroseismic maps of strong earthquakes which occurred in Romania during the non-instrumental period.
A revised, more consistent historical catalogue will allow a more realistic assessment of the seismic hazard, at both regional and local scales. Special attention is paid to the integration and standardization of data and procedures in the cross-border areas, in agreement with ERA (European Research Area) strategy.
- Seismic source physics – The studies are concentrated on: (1) source parameter determination (seismic moment tensor – focal mechanism, source time function) using waveform inversion and relative deconvolution techniques; (2) scaling relations for the source parameters; (3) modelling of the seismic process in Vrancea region, geodynamic scenarios.
- Seismicity – The studies are focused on peculiarities of the seismic activity from different seismogenic regions (clustering, migration of hypocenters, size distribution), space-time statistical modeling of the seismicity, detailed analysis of seismicity bursts (earthquake sequences, swarms) in relation with the local tectonics.
- Seismic hazard – The main objective of the work is the assessment of the seismic hazard on the territory of Romania. Probabilistic hazard analyses are carried out, at both local and regional scales. Several studies cover various aspects related to the hazard assessment (characterization of the seismic source zones, attenuation relations, effects of rupture directivity). The results aim to contribute to the formulation of a reliable national building code, to validate or improve the present input specifications.
- Earthquake forecasting – The studies are oriented towards the monitoring of several reported seismic precursors (seismicity patterns, b-value, energy release) and several natural fields (geomagnetic field, ionosphere, electric field), in order to detect anomalies which are potentially related to strong earthquake occurrence.
