“…For the M w 5.5 case the depth to the top of rupture is 5.3 km, while for the M w 7.5 case the depth is 0.2 km. The model of Kawashima and Aizawa (1989) has magnitudes converted from M JMA to M w using the relationship of Fukushima (1996), while the models of Papazachos et al (1992) and Koutrakis et al (2002) have M S values converted to M w using the conversion of Ambraseys and Free (1997).…”

“…Although not immediately apparent in these plots on logarithmic axes, the differences between the D BA 0:10g and D UA 0:10g durations at 100 km is a small fraction of a second for all magnitudes. Figure 9 compares predictions of bracketed duration from the new equations with three previously published models, one derived from Japanese data (Kawashima and Aizawa, 1989) and two derived from Greek strong-motion data (Papazachos et al, 1992;Koutrakis et al, 2002). These comparisons are hampered by the use of different parameter definitions in the models; adjustments are made for magnitude scales as explained in the figure caption.…”

The complete characterization of earthquake ground motion includes the length of the interval of strong shaking as well as the amplitude and frequency content of the time series. There are relatively few published equations available for the prediction of strong-motion duration from earthquakes, which may in part be a consequence of the fact that the duration of shaking has generally not been considered in structural engineering. Recognizing that there are many applications for which an estimate of the duration of ground motion is needed, this study presents new empirical predictive equations for a number of definitions of strong-motion duration using the records from the Next Generation of Attenuation (NGA) global database of accelerograms from shallow crustal earthquakes. The equations can be used to estimate ground-motion durations from shallow crustal earthquakes of magnitude between M w 4.8 and 7.9 at distances up to 100 km from the source.

“…In Greece, the number of reported predictive ground motion equations has rapidly increasing due to the improvement and expansion of the strong motion networks in recent years (Danciu and Tselentis, 2007;Koutrakis, 2000;Koutrakis et al, 2002Koutrakis et al, , 1999Margaris et al, , 1990Papoulia and Stavrakakis, 1990;Skarlatoudis et al, 2003;Papazachos, 1992, 1994).…”

Abstract. Seismic hazard assessment represents a basic tool for rational planning and designing in seismic prone areas. In the present study, a probabilistic seismic hazard assessment in terms of peak ground acceleration, peak ground velocity, Arias intensity and cumulative absolute velocity computed with a 0.05 g acceleration threshold, has been carried out for Greece. The output of the hazard computation produced probabilistic hazard maps for all the above parameters estimated for a fixed return period of 475 years. From these maps the estimated values are reported for 52 Greek municipalities. Additionally, we have obtained a set of probabilistic maps of engineering significance: a probabilistic macroseismic intensity map, depicting the Modified Mercalli Intensity scale obtained from the estimated peak ground velocity and a probabilistic seismic-landslide map based on a simplified conversion of the estimated Arias intensity and peak ground acceleration into Newmark's displacement.

“…The first effort was performed by Galanopoulos and Delibasis (1972), who studied the maximum expected macroseismic intensity distribution in order to estimate the seismic hazard in Greece, while Shebalin et al (1976) published a similar study for the Balkan peninsula. Several other studies were performed for the broader Aegean area (Algermissen et al, 1976;Makropoulos and Burton, 1985;Drakopoulos and Stavrakakis, 1988;Papoulia and Stavrakakis, 1990;Koutrakis et al, 2002;Tsapanos et al, 2003;Vamvakaris et al, 2008;Tselentis and Danciu, 2010;Vamvakaris, 2010, among others). Papaioannou (1984), studied IMM and PGA using the mean value method (Wiechert and Milne, 1979) and the asymptotic distribution of extreme values (Gumbel, 1958).…”
