Precursory effects in the nighttime VLF signal amplitude for the 18th January, 2011 Pakistan earthquake
TL;DR: In this paper, the amplitude of the nighttime VLF signals anomalously fluctuated 4 days before the Indian Navy station VTX received an earthquake of magnitude 7.4 at Southwestern Pakistan (latitude 28.9°N, longitude 64°E).
Journal ArticleDOI
VLF signals in summer and winter in the Indian sub-continent using multi-station campaigns
Sonali Chakrabarti,Sonali Chakrabarti,Sushanta Kumar Mondal,Sudipta Sasmal,Samir Kumar Pal,Tamal Basak,S. K. Chakrabarti,Debashis Bhowmick,Suman Ray,Surya K. Maji,A. Nandi,Vipin K. Yadav,T. B. Kotoch,Balaram Khadka,Kinsuk Giri,Sudip K. Garain,Asit K. Choudhury,N. N. Partra,Naseer Iqbal +18 more
TL;DR: In this article, the amplitude variation of the diurnal signal at each of these receiving stations in winter and summer was compared and the results generally agree with the signal shapes obtained using the long wave propagation capability code based on mode propagation through the Earth-ionosphere cavity.
Journal ArticleDOI
Ionospheric anomaly due to seismic activities-III: correlation between night time VLF amplitude fluctuations and effective magnitudes of earthquakes in Indian sub-continent
TL;DR: In this article, the authors present the results of an analysis of night time data of the VLF signal amplitude from the Indian Navy station VTX at 182 kHz, received by the Indian Centre for Space Physics, Kolkata.
Journal ArticleDOI
VLF campaign during the total eclipse of July 22nd, 2009: Observational results and interpretations
Sandip K. Chakrabarti,Sandip K. Chakrabarti,Samir Kumar Pal,Sudipta Sasmal,Sushanta Kumar Mondal,Suman Ray,Tamal Basak,Surya K. Maji,Balaram Khadka,Debashis Bhowmick,A.K. Chowdhury +10 more
TL;DR: In this paper, the authors present the results of their campaign and give an interpretation of the results using the Long Wavelength Propagation Capability (LWPC) code in a perturbed waveguide both for the easterly and westerly propagation paths.
Journal ArticleDOI
Unusual behavior of Very Low Frequency signal during the earthquake at Honshu/Japan on 11 March, 2011
TL;DR: In this paper, the authors present evidence of unusual very low frequency (VLF) signal amplitude variation during the devastating earthquake of magnitude 9.0 which occurred at Honshu, in Japan on 11 March, 2011.
