Prediction of the date, magnitude and affected area of impending strong earthquakes using integration of multi precursors earthquake parameters [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2011
Usually a precursor alone might not be useful as an accurate, precise, and stand-alone criteria for the earthquake parameters prediction. Therefore it is more appropriate to exploit parameters extracted from a variety of individual precursors so that ...

Current challenges for preseismic electromagnetic emissions: shedding light from micro-scale plastic flow, granular packings, phase transitions and self-affinity notion of fracture process [PDF]

open access: yes, 2013
Are there credible electromagnetic (EM) EQ precursors? This a question debated in the scientific community and there may be legitimate reasons for the critical views.

Diurnal and semidiurnal cyclicity of Radon (222Rn) in groundwater, Giardino Spring, Central Apennines, Italy [PDF]

open access: yes, 2018
Understanding natural variations of Rn (222Rn) concentrations is the fundamental prerequisite of using this radioactive gas as a tracer, or even precursor, of natural processes, including earthquakes. In this work, Rn concentrations in groundwater were

Detecting ionospheric anomalies associated with three Japan Miyako earthquakes to show their correlations and associated earthquake-induced tsunamis

open access: yesGeodesy and Cartography, 2016
This study employed two-dimensional principal component analysis (2DPCA) for the detection of anomalies in the two-dimensional ionospheric total electron content (TEC) associated with Japan three earthquakes and earthquake-induced tsunamis. From 04:40 to

A compilation of precursor times of earthquakes in Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2021
The precursor time, T, is the time interval between the occurrence time of a precursor and that of a forthcoming earthquake with local magnitude, ML. The precursors are classified into four types of earthquake prediction with different time windows: long-

Early warning of tsunami from seismo-ionospheric fluctuation after Japan’s March 11, 2011, M=9.0 Tohoku earthquake using two-dimensional principal component analysis

open access: yesAnnals of Geophysics, 2015
Two-dimensional principal component analysis (2DPCA) is implemented to analyze the total electron content (TEC) anomalies after Japan’s Tohoku earthquake that occurred at 05:46 on March 11, 2011 (UTC) (Mw=9).

Classes of low-frequency earthquakes based on inter-time distribution reveal a precursor event for the 2011 Great Tohoku Earthquake [PDF]

open access: yes, 2018
Recently, slow earthquakes (slow EQ) have received much attention relative to understanding the mechanisms underlying large earthquakes and to detecting their precursors. Low-frequency earthquakes (LFE) are a specific type of slow EQ.

Predictability of Volcano Eruption: lessons from a basaltic effusive volcano [PDF]

open access: yes, 2003
Volcano eruption forecast remains a challenging and controversial problem despite the fact that data from volcano monitoring significantly increased in quantity and quality during the last decades.This study uses pattern recognition techniques to ...

Thermal Anomalies Detection Using Comparative Method for Small Earthquake

open access: yesMATEC Web of Conferences, 2018
Thermal anomaly is one of the earthquake precursor in the earthquake preparatory phase. Remote sensing in thermal region has been employed based on the concept of stress accumulation in the active plate tectonics region, which may be transformed as ...
