Abstract
HT
| All | Selected | Percent kept | Nb. Secondly, we have subdivided the Italian area into two zones selecting earthquakes with magnitude HT ht occurring in the Apennines (defined as a rectangular area from 41 to 44 HT ht N latitude and 9 to 15 HT ht E longitude) and elsewhere outside this area. For the first investigation, we have followed [50] (see also the recent work by [21]), who found that in the 2008 bulletin 99.6 % of the blasts have local magnitude HT ht (Fig. The Fig. a shows the distribution of the polarities for the chosen target area in the Apennines, while Fig. c exhibits the polarities in the same area but only along back azimuth approximately NE-SW (i.e., the ranges 15-105 HT ht and 195-285 HT ht ).
