“…During the January period, neither typhoons nor storms were observed in the Pacific Ocean area under consideration. Thus, in spite of the negative regular trend during this time of the year [3], the detected temperature anomalous growth was caused, to our mind, by the appearance of an additional heat source. The state of solar, seismic and cyclonic activity allows us to make the conclusion that this source is of seismic nature.…”

“…Indeed, in the papers [1,2] it was discovered that thunderstorm processes appeared after powerful solar flares accompanied by solar radiation increase in spectrum visible and infrared ranges. Moreover, the authors [3] also found thunderstorm phenomena 6-7 days before strong earthquakes with magnitude M > 8.…”

Winter thunderstorms in Kamchatka are rare meteorological phenomena. To investigate the nature of this phenomenon, time variations of quasistatic electric field and meteorological quantities at «Paratunka» observatory, IKIR FEB RAS (φ = 52:97° N; λ = 158:25° E), and the data on solar, seismic and cyclonic activities available in INTERNET were used as a thunderstorm activity indicator. It was shown that powerful solar flares accompanied by radiation increases in visible and infra-red spectra as well as the Earth infra-red radiation entering the atmosphere before powerful earthquakes with magnitude M > 8 may be additional sources of heat in the near-ground atmosphere of Kamchatka. The impact of tropical cyclones on the processes of thunderstorm activity formation in Kamchatka during weak seismic activity has been determined insufficiently and requires further detailed investigation.

“…Many papers related to atmospheric observations at the time of earthquakes have been published. Change of meteorological parameters and particularly increase of temperature has been noticed by [22] before strong earthquakes in Kamchatka. It has been mentioned that the perturbations of the electric conductivity of the atmosphere caused by the ionized gas release may induce lightning discharges [23].…”

The aim of this study is to check if there is a relationship between the seismic activity and the whistlers observed by the micro-satellite DEMETER. Whistlers are the waves emitted by lightning strokes during thunderstorm activity. They use to propagate in the Earth-ionosphere waveguide but also in the ionosphere and the magnetosphere mainly along the magnetic field lines. Due to this reason we have checked the whistler occurrence not close to earthquake epicenters but close to the magnetically conjugate point of these epicenters at the satellite altitude. The number of whistlers is given by a neural network in operation onboard the satellite. It appears that the whistler amplitude is attenuated at the satellite altitude around the magnetic equator. It is why we have removed the earthquakes occurring at low geomagnetic latitudes in the statistic. The whistler rate is normalized with a background value to take into account the seasons and the epicenter locations. A superposed epoch method is used to display the results between −15 and +5 days around the earthquake day and up to 1000 km from the conjugate point of the epicenters. It is shown that the whistler rate is higher the day before the earthquake at a distance less than 200 km. It would be unrealistic to believe in the possibility to use this study for earthquake prediction because everyday thunderstorm activity reliably masks seismic effects. But it is further evidence that there is a lithosphere-atmosphere-ionosphere coupling at the time of the seismic activity.

“…The early measurements of anomalous atmospheric electric field before earthquakes were made by Bonchkovsky (1954) and Kondo (1968), and recent measurements with modern techniques confirmed the results (Hao, 1988;Smirnov, 2008;Choudhury et al, 2013;Bychkov et al, 2017;Smirnov et al, 2017). Since the atmospheric electric field is abnormal before the earthquake, can we use this method to predict an earthquake?…”

Physical phenomena observed before strong earthquake have been reported over centuries. Radon anomalies, electrical signals, water level changes, earthquake lights near the epicenter are recognized as pre-earthquake signals to approach earthquake prediction. Anomalous negative signals observed by ground-based atmospheric electric field instrument under fair weather open up a new way to earthquake prediction. Abnormal heat radiation before the earthquake bring fair weather around the epicenter in theory. In order to figure out the weather conditions around the epicenter before earthquakes, 213 global earthquake events with magnitude of 6 or above from 2013 to 2020 were collected. Based on our definition of fair weather, in 96.7% of the events in the statistics, the weather before the earthquake is fair. Besides, the fair state before the earthquake lasted more than 7 hours, leaving us with enough early warming time.
