Statistical significance of the precursory minima of the order parameter fluctuations of seismicity by modern methods of Statistical Physics » An order parameter for seismicity was introduced in the frame of natural time analysis [1]. Recent studies of the fluctuations of this order parameter revealed the existence of minima preceding major earthquakes [2-7]. Here, we review the statistical significance of these minima by using recent methods of Statistical Physics, such as receiver operating characteristics [8] and event coincidence analysis [9,10]. These methods are also applied to the investigation [11] of the statistical significance of Seismic Electric Signals [12].ReferencesVarotsos, P.A.; Sarlis, N.V.; Skordas, E.S.

Evolution of tsunami warning systems and products | Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences » Each year, about 60 000 people and $4 billion (US$) in assets are exposed to the global tsunami hazard. Accurate and reliable tsunami warning systems have been shown to provide a significant defence for this flooding hazard. However, the evolution of… Royalsocietypublishing.org
