Abstract
A local magnitude scale has been defined for southern Italy, in the area
monitored by the recently installed Irpinia Seismic Network.Waveforms recorded from
more than 100 events of small magnitude are processed to extract synthetic Wood–
Anderson traces. Assuming a general description of peak-displacement scaling with
the distance, by means of linear and logarithmic contributions, a global exploration
of the parameter space is performed by a grid-search method with the aim of investigating
the correlation between the two decay contributions and seeking for a physical solution
of the problem. Assuming an L2 norm, we found
M log A 1:79 log R 0:58;
yielding an error on the single estimation smaller than 0.2, at least when the hypocenter
location is accurate. Station corrections are investigated through the station residuals,
referring to the average value of the magnitude. Using a z test, we found that some stations
exhibit a correction term significantly different from 0. The use of the peak acceleration
and peak velocity as indicators of the magnitude is also investigated.
