Rezumat

We report on peak ground accelerations (PGAs) recorded for three strong earthquakes in Vrancea, Romania (August 30, 1986, moment magnitude Mw = 7.1; depth h = 131.4 km; May 30, 1990, Mw = 6.9 depth 90.9 km; May 31, 1990, Mw = 6.4 depth 86.9 km & October 28, 2018, Mw = 5.5 depth 147.8 km). The PGAs increase with increasing epicentral distance, and then decrease for larger distances. These real data may be a new chalenge for the probabilistic seismic hazard studies or other methodologies, which take the epicentral PGA as a basic input parameter. To our knowledge, this phenomenom has not been reported elsewhere. Its spatial regularity leaves open the possibility of ascribing it to the soil particularities, like non-linearities.
