Several parameters of strong motion are evaluated and discussed. Emphasis is given on records from small-to-moderate magnitude earthquake events with M<6.0 which are found to satisfy several damage potential criteria, when recorded at small distances from the source. These records are characterized by pulses of shorter duration and smaller peak ground velocity, PGV, than records of greater earthquake magnitude, while representing forward directivity phenomena. Such events can cause extensive damage to medium period structures with fundamental period less than 1 sec which are located close to active faults. A simple expression, based on the ratio of spectral velocity (SV) to peak ground velocity (PGV), is proposed as a criterion to identify the velocity pulse type of near-source records.
