Natural hazards (NH), such as earthquakes, tsunamis, volcanic eruptions, and severe
tropospheric weather events, generate acoustic and gravity waves that propagate upward …

The electromagnetic coupling between the seismically activated area and the ionosphere is
considered within the framework of the Global Electric Circuit (GEC) conception. First we …

The Tonga volcano eruption at 04: 14: 45 UT on 2022-01-15 released enormous amounts of
energy into the atmosphere, triggering very significant geophysical variations not only in the …

This paper describes the current understanding of the interaction between geospheres from
a complex set of physical and chemical processes under the influence of ionization. The …

The article is a review of studies of ionospheric effects carried out in ISTP SB RAS. The main
results of GPS/GLONASS radio sounding of ionospheric disturbances of natural and …

Using GPS total electron content (TEC) measurements, we analyzed ionosphere response
to the great Kurile earthquake of 4 October 1994. High spatial resolution of the Japanese …

1Hz GPS measurements from the Japanese GPS network GEONET allowed to retrieve
information on the seismic fault of the great M9. 0 Tohoku‐oki earthquake from the …

At 17: 47 UT on 20 September 1999, a large earthquake of magnitude Mw 7.6 struck the
central Taiwan near a small town of Chi‐Chi. The ground‐based receivers of the global …

We review observations on the coupling between Earth's surface disturbances and the
upper atmosphere. In particular, we focus on the upper atmospheric responses to …

Abstract Using Total Electron Content (TEC) measurements with Global Positioning System
we studied ionospheric responses to three large earthquakes that occurred in the Kuril Arc …
