The New Zealand Kaikoura Earthquake (Mw 7.8, 14 November 2016) produced co-seismic flashes of earthquake light near the ground at midnight, 230 km north epicentre. Mostly, there was a white hemisphere in atmosphere just above ground, up to 250 m radius, colour becoming radially increasingly dark blue. Fifteen videos were available for analysis which led following new or reaffirmed conclusions: (i) blue is due Rayleigh Scattering (new explanation); (ii) also sometimes occurs within low clouds...
<p>Earthquake light (EQL) mainly blue-white flashes from the ground, was observed coseismically during a NewZealand M7.1 earthquake, (4.47 am 4-Sep-2010 local time). A production mechanism is most probable. The flash observations support Freund et al. mechanism, i.e. shockwave disturbance creating electronic“holes” ruptured peroxy bonds in quartz, and subsequent surface positive charge followed by emission neutralization. Examination of video records shows median length about half...
Abstract. Previous published work after the Kobe and İzmit earthquakes (1995 1999, respectively) demonstrated some reported meteorological animal behaviour precursors were valid. Predictions freshly tested for Christchurch earthquake (M = 7.1, 4 September 2010). An internet survey with nearly 400 valid replies showed relative numbers of reports in precursor categories day before quake, statistically significantly different from those preceding three days (excess events behaviour). The there...
Abstract Electron spin resonance (ESR) and 230 Th/ 234 U ages of speleothem samples collected from karstic caves located around 3000 m elevation in the Aladağlar Mountain Range (AMR), south-central Turkey, were determined order to provide new insight information regarding late Pleistocene climate. ESR validated with test samples. The 21 different layers six found range mostly between about 59 4 ka, which cover Marine Oxygen Isotope Stages (MIS) MIS 3 1. Among all, only appear have deposited...
Abstract. This article examines retrospective public-supplied precursor reports statistically, and confirms published hypotheses that some alleged precursors within 100km a day prior to the large 1995 Kobe 1999 Izmit earthquakes, may be valid. The confirmations are mostly at p<0.001 level of significance. Most significant were meteorological geophysical precursors, less often, animal reports. chi-squared test used, for first time eliminates distorting effects psychological factors on...
Lithium oxalate (Li-oxalate: Li 2 C O 4 ) and magnesium (Mg-oxalate: MgC ·2H O) were investigated by electron spin resonance (ESR) spectroscopy as new ESR dosimeter materials. The spectra of Li- Mg-oxalates irradiated γ-rays have a singlet with spectroscopic splitting factor ( g -factor) =2.0043±0.0004 are ascribed to self-trapped hole, the radical - . A broad signal formed high dose irradiation is considered be due zero field fine structure splitting, D S / β\cong0.65 mT) for triplet state...
Earthquake light, emerging from the ground as flashes at night (neglecting other more minor forms), usually has a white hemispherical center and blue outer part. The resembles daytime sky. Its existence is increasingly verified, with about 80 videos on web to mid-2017. However, light must be differentiated power-grid faults, so sound/color/form/length criteria were developed in this paper through examination of many videos. Light should coseismic (i.e. when S-waves arrive), hemispherical,...
A statement of split sea in the Izmit Gulf, where North Anatolian Fault is extending, was obtained from a witness fisherman when we collected retrospective statements about unusual phenomena before earthquake 1999. The and walls seawater on both sides his boat, which name Moses' phenomenon after Exodus, were ascribed to larger outflow out fault zone at time faulting than inflow outside sea. water removal by preseismic dilatancy large areas fissures breccia addition horizontal due subsidence...
The paramagnetic centres used for ESR (Electron Spin Resonance) dating method should be thermally stable which is the main factor limiting range of this method. In work, thermal stabilities in cave deposites from Aladaǧlar Massive and Alanya Turkey has been investigated. life times signal were calculated as about 4.0 3.7 years G06 G08 samples at 10 °C depositing temperature. activation energies are obtained same, 0.7eV both samples.
Quartz minerals extracted from ignimbrites belonging to Tahar units of \"{U}rg\"{u}p formation in Kapadokya, Turkey, were dated by electron spin resonance (ESR). The obtained equivalent dose the Al center was larger than that Ti experimental error. Annealing experiments indicate artificial \gamma-ray irradiation produces less stable centers both irradiated and non-irradiated quartz. Ages samples different sizes using centers. It is concluded age more reliable, order (10^{6} years) falls into...
&lt;p&gt;During the co-seismic development of a fault in lithological environments, regions containing cavities may form momentarily or permanently. In tectonic shift zones, these pressure gaps lead to formation irregular new intermediate sediment as infiltrate gap, if perturbations are large. The semi-fluid material and sea water enter through opening sector's surrounding sediments at far place from dispersing energy burst. But pore infiltration is independent about vomited some...
