The LVD signals during the early-mid stages of the L'Aquila seismic sequence and the radon signature of some aftershocks of moderate magnitude.

摘要: The L'Aquila seismic swarm culminated with the mainshock of April 6, 2009 (ML = 5.9). Here, we report and analyze Large Volume Detector (LVD, used in neutrinos research) low energy traces (∼0.8 MeV), collected during early-mid stages sequence, together data a radon monitoring experiment. peaks LVD do not correlate evolution magnitude earthquakes, including major aftershocks. Conversely, our measurements obtained by utilizing three automatic stations deployed along regional NW-SE faulting system, seem to be, one case, more efficient. In fact, timeseries on Paganica fracture recorded marked variations that occurred prior moderate aftershocks (with ML > 3). station (PGN) seems better responds active seismicity due fact detector was placed directly within bedrock an fault. It is suggested future networks for should preferentially implement this setting.
