Microseismic impulses as earthquake precursors

Izvestiya, Physics of the Solid Earth, 2006
Records of the IRIS broadband stations in Petropavlovsk-Kamchatski, Yuzhno-Sakhalinsk, Magadan, Yakutsk, Arti, and Obninsk obtained before the Kronotskii (Kamchatka Peninsula) M = 7.7 earthquake of December 5, 1997, and the Neftegorsk (Sakhalin Island) M = 7.0 earthquake of May 27, 1995, are investigated with the use of the Spectra Analyzer interactive

Classification of earthquake precursors

Tectonophysics, 1979
Abstract In view of the fact that fairly many data on earthquake precursors have been reported in recent years, some statistics concerning precursor times are again presented on the basis of the previous and newly-added data. The previous conclusion that the precursors can be classified into three kinds is reconfirmed very positively.

Earthquake precursors in Japan: Precursor time and detectability

Tectonophysics, 1987
Abstract Earthquake precursor data amounting to 418 in number accumulated in Japan are analyzed. Most data are obtained under the nation-wide earthquake prediction programme. The precursor time ( T ) versus main shock magnitude ( M ) relationship is different for different groups of precursors. A linear relation such as: log T = a + bM where a

A Search for Earthquake Precursors

Science, 1996
Geochemical signals that precede an earthquake might offer the hope of early warning and evacuation. The existence of such precursors is extremely controversial, however, as early optimism has turned into skepticism. In their Perspective, Silver and Wakita discuss new work on precursor events that was presented at a conference in Tokyo.

Radon as an earthquake precursor

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2004
Radon concentrations in soil gas were continuously measured by the LR-115 nuclear track detectors during four years. Also seismic activities, as well as the barometric pressure, rainfall and air temperature were observed. The influence of the meteorological parameters to the temporal radon variations was investigated and the respective equation of the ...

Spatial selectivity of earthquake’s precursors

Physics and Chemistry of the Earth, Parts A/B/C, 2006
Abstract Multiparameter monitoring of earthquake’s (EQ) precursors reveals their selective localization (selectivity), i.e. a precursor can be observable in relatively small selected sensitive area(s) and not observable over remaining vast region. Selectivity and long distance appearance of precursors are rather strange and difficult for explanation,
