Abstract: | —Properties of the earthquake sequence of the 23 January, 1992 (5.8 M S ?) earthquake in Cephalonia Island, Western Greece, are investigated. The parameter b in the frequency-magnitude relation is found equal to 1.084 while the decay parameter p of the time distribution of the aftershock sequence is found equal to 0.991. The principal parameters method is applied to the aftershock sequence and the average strikes of N156°E (±20°) and N61°E (±10°) were obtained denoting also very small dips. The major strike which resulted from the aftershock epicentre distribution was NW–SE, similar to Miocene-Neogene basins on Cephalonia Island. |
