      abstract     = {Monitoring of environmental radioactivity for the purpose
                      of earthquake prediction requires the discrimination of
                      anomalies of non-tectonic origin from seismically-induced
                      anomalies. This is a challenging task as time series of
                      environmental radioactivity display a complex temporal
                      pattern reflecting a wide range of different physical
                      processes, including meteorological and surface effects. The
                      present study is based on the detailed time series of gamma
                      radiation from the Eastern North Atlantic (ENA) site in the
                      Azores, and on very high resolution precipitation intensity
                      and soil moisture time series. The results show that an
                      abrupt shift in the average level of the gamma radiation
                      time series previously reported as a potential earthquake
                      precursor can also be explained by a corresponding abrupt
                      change in soil moisture. It was concluded that the reduction
                      of false positive earthquake precursors requires the
                      detailed assessment of both precipitation and soil moisture
                      conditions at high temporal resolution.},
