| description | The definition of the network resolution power is an important parameter to
be considered when evaluating most of the seismic analysis, being connected
to the location quality and earthquakes detectability.
<br><br>
We estimated the resolving power of the seismic network of Campi Flegrei. The
results show that the actual moment magnitude threshold is 0.5 in the
Solfatara area, center of the caldera, but increases sharply going away from
the center.
<br><br>
We also estimated the theoretical resolution power of the actual seismic
network of Campi Flegrei plus 5 hypothetical borehole stations, moving the
borehole stations into 3 different wells. As expected, big improvements in
the location parameters come from the use of borehole stations. The results
show that a 3000 m deep borehole located close to the actual hypocentral
area would allow to detect and locate the very low magnitude earthquakes,
probably connected to the hydrothermal system characterizing the Campi
Flegrei caldera.
<br><br>
Finally, we performed an optimization analysis of the permanent seismic
network of Campi Flegrei finding the best 3 station positions that would
increase the resolution power of the network to locate earthquakes in the
South and offshore part of the caldera. We evidenced that the actual network
has an improvable resolution in the South and West part of the caldera. |
