Abstract :

Understanding strong ground motions in the near-fault areas is important for seismic risk assessment in densely populated areas. In the past, lack of information on strong ground motion for large and moderate earthquakes led to the use of mainly far field large and moderate earthquake records in equations for calculation of the strong ground motion parameters. In this article, we collected and generated a seismic catalogue with a data set of corrected and processed 217 triaxial near source strong ground motion and accelerometric data recorded from 1976 to 2018 obtained from 30 shallow crustal earthquakes with a focal depth below 30 km from different regions including 24 in Iran, 5 in California and one in Italy (because of the lack of Iranian near-field accelerograms) in different stations. These data were recorded (129 Iranian records, 88 from California and Italy) with a source-to-site distance less than 80 km and earthquakes between Mw = 5 and 7.5. Receiver function method was used for site classification for these records. The percentage of processed data in this study was 18%, 43%, 33% and 6% for the different site classes of 1, 2, 3, and 4. In the final catalog, records in which their PGA≥ 100 cm /s2, were reported. This near source ground motion database also contains information about ground motion, source parameters and is fundamental for dynamic research in earthquake engineering for the estimation of strong ground motion parameters (PGA, PGV, PGD and frequency content of response spectra) of moderate-to-large earthquakes.
