A characteristic change of seismicity has been recently uncovered when the precursory Seismic Electric Signals activities initiate before an earthquake occurrence. In particular, the fluctuations of the order parameter of seismicity exhibit a simultaneous distinct minimum upon analyzing the seismic catalog in a new time domain termed natural time and employing a sliding natural time window comprising a number of events that would occur in a few months. Here we focus on the minima preceding all… Expand

Natural Time Analysis: The Area under the Receiver Operating Characteristic Curve of the Order Parameter Fluctuations Minima Preceding Major Earthquakes
Fifteen distinct minima—observed simultaneously at two different natural time scales and deeper than a certain threshold—are found on analyzing the seismicity of Japan from 1 January 1984 to 11 March 2011 (the time of the M9 Tohoku EQ occurrence) 1 to 3 months before large EQs. Expand
Detrended fluctuation analysis of seismicity and order parameter fluctuations before the M7.1 Ridgecrest earthquake
Detrended fluctuation analysis (DFA) has been recently applied for the investigation of temporal correlations between the earthquake magnitudes before major earthquakes. Here, we employ DFA togetherExpand
MW9 Tohoku earthquake in 2011 in Japan: precursors uncovered by natural time analysis
This paper reviews the precursory phenomena of the 2011 MW9 Tohoku earthquake in Japan that emerge solely when we analyze the seismicity data in a new time domain termed natural time. If we do notExpand
Minima of the fluctuations of the order parameter of seismicity and earthquake networks based on similar activity patterns

Study in Natural Time of Geoelectric Field and Seismicity Changes Preceding the Mw6.8 Earthquake on 25 October 2018 in Greece
The analysis in natural time of the seismicity subsequent to the SES activity in the area candidate to suffer this strong earthquake reveals that the criticality conditions were obeyed early in the morning of 18 October 2018, i.e., almost a week before the strong earthquake occurrence. Expand
Identifying the Occurrence Time of the Deadly Mexico M8.2 Earthquake on 7 September 2017
Based on natural time analysis, which enables the introduction of an order parameter for seismicity, a procedure through which the identification of the occurrence time of the M8.2 earthquake that occurred on 7 September 2017 in Mexico in Chiapas region is discussed. Expand
Statistical physics models for aftershocks and induced seismicity
Nowcasting is introduced to extend RI forecasting to time-dependent seismicity, for example, during an aftershock sequence, and it is shown how nowcasting can be used to assess the success of these efforts to reduce the seismic activity. Expand
Low-Frequency Seismic Noise Properties in the Japanese Islands
The main conclusions of the conducted studies are that the preparation of a strong earthquake is accompanied by a simplification of the structure of seismic noise, and bursts of coherence between the time series of the day length and the noise properties within annual time window precede bursts of released seismic energy.

Minimum of the order parameter fluctuations of seismicity before major earthquakes in Japan
It is found that the fluctuations of the order parameter of seismicity exhibit distinct minima a few months before all of the shallow earthquakes of magnitude 7.6 or larger that occurred during this 27-y period in the Japanese area. Expand
