Earthquakes Three-Stage Early Warning and Short-Term Prediction
Manana Kachakhidze, Nino Kachakhidze-Murphy, Giorgi Ramishvili +1
The article discusses the possibilities of three-step early warning and short-term prediction of earthquakes based on the classical geological model of fault formation and a model…
Precursor that predicts the earthquakes, triggers, and indicators
Manana Kachakhidze, Nino Kachakhidze-Murphy, Vaso Kukhianidze +2
it has been given scientifically proven suggestions for the classification of earthquake precursor, indicator, and triggering factors.
Prominence instability and CMEs triggered by massive coronal rain in the solar atmosphere
Z. Vashalomidze, T. V. Zaqarashvili, V. Kukhianidze +3
Triggering process for prominence instability and consequent CMEs is not fully understood. Prominences are maintained by the Lorentz force against the gravity, therefore reduction…
Magneto-Rossby waves in the solar tachocline and the annual variations in solar activity
Tamar Gachechiladze, Teimuraz V. Zaqarashvili, Eka Gurgenashvili +4
Annual oscillations have been detected in many indices of solar activity during many cycles. Recent multi spacecraft observations of coronal bright points revealed slow retrograde…
Large Earthquake Prediction Methods on the Base of INFREP VLF / LF Data
Manana Kachakhidze, Nino Kachakhidze-Murphy, Badri Khvitia +1
In the presented paper the possible methods of the large earthquake prediction are offered. During the study, it was used data of the INFREP (European Network of Electromagnetic Ra…
Quasi-oscillatory dynamics observed in ascending phase of the flare on March 6, 2012
E. Philishvili, B. M. Shergelashvili, T. V. Zaqarashvili +5
Context. The dynamics of the flaring loops in active region (AR) 11429 are studied. The observed dynamics consist of several evolution stages of the flaring loop system during both…
Long-period oscillations of active region patterns: least-squares mapping on second-order curves
G. Dumbadze, B. M. Shergelashvili, V. Kukhianidze +6
Active regions (ARs) are the main sources of variety in solar dynamic events. Automated detection and identification tools need to be developed for solar features for a deeper unde…
Rieger-type periodicity during solar cycles 14-24: estimation of dynamo magnetic field strength in the solar interior
Eka Gurgenashvili, Teimuraz Zaqarashvili, Vasil Kukhianidze +6
Solar activity undergoes a variation over time scales of several months known as Rieger-type periodicity, which usually occurs near maxima of sunspot cycles. An early analysis show…
Dynamics of a solar prominence tornado observed by SDO/AIA on 2012 November 7-8
I. Mghebrishvili, T. V. Zaqarashvili, V. Kukhianidze +4
We study the detailed dynamics of a solar prominence tornado using time series of 171, 304, 193 and 211 Å spectral lines obtained by Solar Dynamics Observatory/ Atmospheric Imaging…
Formation and evolution of coronal rain observed by SDO/AIA on February 22, 2012
Z. Vashalomidze, V. Kukhianidze, T. V. Zaqarashvili +5
The formation and dynamics of coronal rain are currently not fully understood. Coronal rain is the fall of cool and dense blobs formed by thermal instability in the solar corona to…
In connection with identification of VLF emissions before L'Aquila earthquake
M. Kachakhidze, Z. Kereselidze, N. Kachakhidze
The present paper deals with an attempt to check up the theoretical model of self-generated seismo-electromagnetic oscillations of LAI system on the basis of retrospective data. Ap…
Doppler shift oscillations in solar spicules
T. V. Zaqarashvili, E. Khutsishvili, V. Kukhianidze +1
Consecutive height series of Ha spectra in solar limb spicules taken on the 53 cm coronagraph of Abastumani Astrophysical Observatory at the heights of 3800-8700 km above the photo…
