abstract="A method is presented to detect earthquake precursors from time series data on  earthquakes in a target region. The Regional Entropy of Seismic Information (RESI)  is an index that represents the average influence of an earthquake in a target  region on the diversity of clusters to which earthquake foci are distributed. Based  on a simple qualitative model of the dynamics of land crust, it is hypothesized that  the saturation that occurs after an increase in RESI precedes the activation of  earthquakes. This hypothesis is validated by the earthquake catalog. This temporal  change was found to correlate with the activation of earthquakes in Japanese regions  one to two years ahead of the real activation, more reliably than the compared  baseline methods.<p /> <p>Language: en</p>",
