Investigation of the Pre- and Co-Seismic Ionospheric Effects from the 6 February 2023 M7.8 Turkey Earthquake by a Doppler Ionosonde

Autor: Nazyf Salikhov, Alexander Shepetov, Galina Pak, Serik Nurakynov, Azamat Kaldybayev, Vladimir Ryabov, Valery Zhukov

Publikováno v: Atmosphere, Vol 14, Iss 10, p 1483 (2023)

During the catastrophic M7.8 earthquake in Turkey on 6 February 2023, anomalous effects were revealed in the ionosphere associated with various propagation mechanisms of seismogenic disturbance from the lithosphere up to the height of the ionosphere.

Disturbances of Doppler Frequency Shift of Ionospheric Signal and of Telluric Current Caused by Atmospheric Waves from Explosive Eruption of Hunga Tonga Volcano on January 15, 2022

Autor: Nazyf Salikhov, Alexander Shepetov, Galina Pak, Vladimir Saveliev, Serik Nurakynov, Vladimir Ryabov, Valery Zhukov

Publikováno v: Atmosphere, Vol 14, Iss 2, p 245 (2023)

After the explosive eruption of the Hunga Tonga volcano on 15 January 2022, disturbances were observed at a distance of about 12,000 km in Northern Tien Shan and regarded variations in the atmospheric pressure, in telluric current, and in the Doppler
