Rayleigh waves in the frequency range 0.7-2.5 Hz are recorded at stations on the Scottish LOWNET array, from local underwater explosions in the Kirkcaldy Bay region of the Firth of Forth. The fundamental mode is identified by comparing theoretical and observed particle motion plots derived from seismograms at the Edinburgh station, this being used as a guide for selection at the other stations. The selected signals are then analysed to obtain estimates of the group velocity dispersion characteristics along isolated event-station paths, and this information is interpreted in two ways:
