Abstract: | The presence of quarry and mine blasts in seismic catalogues is detected using the Wiemer and Baer (Bull Seism Soc Am 90(2):525–530,
2000) algorithm. The procedure is based on the observation that quarry blasts generally take place during daytime hours: the areas
with a high ratio of daytime and night-time events are likely to be regions with quarry activity. In the first part of this
work we have tested the method, using both a synthetic and a regional catalogue; in the second part the procedure has been
applied to some of the European regional catalogues available on line. The comparison between the results obtained and the
location of known quarries and mines for the analysed catalogues confirms the reliability of the methodology in identifying
mining areas. |
