19 Clustered Foreshock Sequences Along the San Jacinto Fault Zone: Possible Role of Frictional Heterogeneity in Extended Earthquake Nucleation

open access: yesGeophysical Research Letters
Laboratory experiments and theoretical models suggest that earthquakes are preceded by extended nucleation phases, perhaps by slow but accelerating slip. However, such nucleation phases are hard to observe before natural earthquakes.

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 ...

Reverse Detection of Short-Term Earthquake Precursors [PDF]

open access: yes, 2003
We introduce a new approach to short-term earthquake prediction based on the concept of selforganization of seismically active fault networks. That approach is named "Reverse Detection of Precursors" (RDP), since it considers precursors in reverse order ...

Transform fault earthquakes in the North Atlantic: Source mechanisms and depth of faulting [PDF]

open access: yes, 1988
The centroid depths and source mechanisms of 12 large earthquakes on transform faults of the northern Mid-Atlantic Ridge were determined from an inversion of long-period body waveforms.

Anomalies Observed in VLF and LF Radio Signals on the Occasion of the Western Turkey Earthquake (Mw = 5.7) on May 19, 2011 [PDF]

open access: yes, 2012
VLF radio signals lie in the 10 - 60 kHz frequency band. These radio signals are used for worldwide navigation support, time signals and for military purposes.

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).
