The direct detection of gravitational waves opens a new window to explore our Universe and indicates the coming of a new era of gravitational wave astronomy. In 2015, the KITPC program on “The Next De...
Researchers from MIT, Princeton University, and elsewhere have developed a new technique to monitor the seasonal changes in Greenland’s ice sheet, using seismic vibrations generated by crashing ocean ...
The polarization method for recognition of seismomagnetic waves against a noise background is presented. The method is applied to detection of magnetic oscillations accompanying the propagation of sur...
T waves in Western Mediterranean Sea after the May 21, 2003 Algerian earthquake
T waves Ligurian Sea SOFAR frequency content

Aim of this paper is to discuss on the T phases generated after the mb 6.5 earthquake that shook Algeria on May 21,
2003. The seismograms, recorded by a cluster of seismic stations located on the coa...
The Rayleigh equation has real coefficients; therefore, also the case of complex conjugated roots may be explained physically. The Author proves that the Somigliana waves may be formed for Poisson rat...
Attenuation of electromagnetic waves at the frequency ~1.7 kHz in the upper ionosphere observed by the DEMETER satellite in the vicinity of earthquakes
Waves and wave analysis Wave propagation
