This paper (Part 1) describes the period and amplitude variations and the re-occurrence of local peaks, during different earthquakes, in the Fourier amplitude spectra of strong ground motion, recorded at seven stations along the Adriatic Coast in Montenegro, Yugoslavia, in the Dinarides and Illyrides seismogenic zone. In the comparison paper (Part II), this analysis will be presented for the Inner Part of Balkan Peninsula seismogenic zone. The data suggest that some local peaks re-occur during shaking by small local earthquakes (peak ground velocities
v
max<10–20 cm/s). During large strong-motion amplitudes (
v
max>20 cm/s), these peaks are shifted toward longer periods (by non-linear response of soils) or disappear.
