Analysis of strong motion data from three events (MW = 4.3–4.9) recorded recently in central Albania area
Abstract We present here the results of the analysis in terms of Brune stress-drop and high-frequency diminution parameters of three strong motion records obtained from events that have occurred in the area of Elbasani (central Albania). The data have been recorded by the digitally upgraded SMA-1 instrument situated in the centre of the Elbasani town on the ground level of a small size, one-story building. We observed two distinct levels of stress-drop: the first level comprises the values 25 bars and 40 bars, while the second one is related with the stress-drop value 250 bars. The first class of the stress-drop is typical for areas of normal focal mechanism, while the last one is typical for areas of thrust focal mechanism. The presence of different faulting mechanisms, evidenced by earthquakes occurring around Elbasani, indicates the complexity of faulting environment in this area. As far as high-frequency diminution parameter is concerned, the lowest values are found for the longitudinal components in the range κ = 0.001–0.026. The analysis of the transversal components resulted with κ values in the range κ = 0.039–0.051. These values are lower than those observed previously for this parameter, for the same soil category.
