Constraints on mechanisms of chondrule formation from chondrule precursors and chronology of transient heating events in the protoplanetary disk
chondrules refractory inclusions chondrule precursors transient heating

The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type
in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...
On the existence of earthquake precursors
Earthquake prediction precursor
font style='font-size:12px;'>
2015/9/30
Earthquake prediction based on precursors can aim to provide fully quantified, time-varying, synoptic forecasts, which do not depart from physical and geological principles, and are amenable to formal...
An integrated study of physical precursors of failure in relation to earthquake prediction, using large scale rock blocks

2015/9/30
This paper is multi-analysis approach to rock failure using metric size rock samples. The use of large-scale models permits simulation of the seismic process (including internal rupture on several sca...
A critical review of Electric Earthquake Precursors
Earthquake precursor earthquake prediction electric earthquake precursor (EEP) seismic electric signal (SES)

2015/9/28
The generation of transient electric potential prior to rupture has been demonstrated in a number of laboratory experiments involving both dry and wet rock specimens. Several different electrification...
Could ionospheric variations be precursors of a seismic event? A short discussion
Ionosphere seismic precursors
font style='font-size:12px;'>
2015/9/28
A short review of published papers on the perturbations in the ionosphere due to seismogenic effects is reported. The method to correlate different classes of phenomena as ionospheric variations and s...
Disturbances in LF radio-signals as seismic precursors
radio signals seismicity precursors
font style='font-size:12px;'>
2015/9/28
Low Frequency (LF) radio signals lie in the band 30-300 kHz. Monitoring equipment able to measure the electric strength of such signals, at field sites with very low noise levels, were designed and as...
Ionospheric precursors to scintillation activity
Scintillations Forecasts Dynamics Inverse methods Algorithms and implementation
font style='font-size:12px;'>
2015/8/17
Ionospheric scintillation is the rapid fluctuation of both phase and amplitude of trans-ionospheric radio waves due to small scale electron density irregularities in the ionosphere. Prediction of the ...
Searching for seismo-ionospheric earthquakes precursors: Total Electron Content disturbances before 2005-2006 seismic events
seismo-ionoispheric earthquake precursors total electron content of ionosphere lithosphere-atmosphere-ionosphere coupling
font style='font-size:12px;'>
2012/5/17
During earthquakes preparation periods significant disturbances in the ionospheric plasma density are often observed. These anomalies are caused by lithosphere-atmosphere-ionosphere interaction, parti...
An attempt to find precursors in the ULF geomagnetic data by means of flicker noise spectroscopy
ULF geomagnetic data means of flicker noise spectroscopy
