Natural Hazards and Earth System Sciences Power law relationship between parameters of earthquakes and precursory electrical phenomena
A number of Seismic Electric signals data have been accumulated during the last two decades that also includes the signals observed before the magnitude 6 class earthquakes that occurred in GreeceExpand
Pre-earthquake signals – Part I: Deviatoric stresses turn rocks into a source of electric currents
Abstract. Earthquakes are feared because they often strike so suddenly. Yet, there are innumerable reports of pre-earthquake signals. Widespread disagreement exists in the geoscience community howExpand
Global Earthquake Forecasting System (GEFS): The challenges ahead
We conclude this special issue on the Global Earthquake Forecasting System (GEFS) by briefly reviewing and analyzing the claims of non-seismic precursors made in the present volume, and by reflectingExpand
The Theoretical and Practical Foundations of Strong Earthquake Predictability
Earthquakes and the tsunamis they produce are the world’s most devastating natural disasters, affecting more than 100 countries. Not surprisingly, the problem of earthquake prediction has occupiedExpand
Assessing the Potential Earthquake Precursory Information in ULF Magnetic Data Recorded in Kanto, Japan during 2000–2010: Distance and Magnitude Dependences
This study uses Molchan's error diagram to evaluate the potential earthquake precursory information in the magnetic data recorded in Kanto, Japan during 2000–2010 and shows that the earthquake predictions based on magnetic anomalies are significantly better than random guesses. 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
On the Statistical Significance of the Variability Minima of the Order Parameter of Seismicity by Means of Event Coincidence Analysis
Natural time analysis has led to the introduction of an order parameter for seismicity when considering earthquakes as critical phenomena. The study of the fluctuations of this order parameter hasExpand
Precursor-Based Earthquake Prediction Research: Proposal for a Paradigm-Shifting Strategy
The article discusses the controversial topic of the precursor-based earthquake prediction, based on a personal perspective intending to stir the current still waters of the issue after twenty yearsExpand
Ultra-low frequency (ULF) magnetic field emissions associated with some major earthquakes occurred in Indian Subcontinent
Abstract We have analyzed ULF magnetic field emissions data obtained from identical 3- component search coil magnetometers installed at Indian stations of Agra (Geograph. lat. 27.2°N, long. 78°E),Expand
Earthquake - A Natural Disaster, Prediction, Mitigation, Laws and Government Policies, Impact on Biogeochemistry of Earth Crust, Role of Remote Sensing and GIS in Management in India - An Overview
The whole world from time to time is exposed to the unpredictable disaster called Earthquake which causes immense damage to the infrastructure, life and injury to the people. The present manuscriptExpand
