Effect of Strong Earthquakes on the Geodynamo
AbstractThe global nature of the induced geomagnetic variations was demonstrated using the magnetic observation data obtained at the INTERMAGNET...

Evolution of the Earth and Geodynamo
Abstract—This paper considers a sequential selection of parameters in a model of cooling of the Earth’s core. The model describes the evolution from...

A secular variation candidate model for IGRF-13 based on Swarm data and ensemble inverse geodynamo modelling
This paper describes the design of a candidate secular variation model for the 13th generation of the International Geomagnetic Reference Field. This...

An alternate representation of the geomagnetic core field obtained using machine learning
Machine learning (ML) as a tool is rapidly emerging in various branches of contemporary geophysical research. To date, however, rarely has it been...

Sustaining Earth’s magnetic dynamo
Earth’s magnetic field is generated by fluid motions in the outer core. This geodynamo has operated for over 3.4 billion years. However, the...

On the Magnetic Effects Caused by the Earthquake of March 16, 2022 in Japan
AbstractThe magnetic effects of two similar underwater earthquakes with magnitudes of 6.0 and 7.3, which occurred on March 16, 2022, were considered...

Earth's Magnetic Field and Magnetosphere
Magnetism is one of the longest known physical phenomena and the Earth's magnetic field was one of the first scientifically studied aspects. The... -
Mesoproterozoic geomagnetic field strength from Nova Guarita mafic dykes (Amazon Craton)
Palaeointensity data from the Precambrian are key to understanding the timing of the Earth’s Inner Core Nucleation (ICN). Due to the scarcity of...

Correspondence between Cosmic-Dust-Enriched Sediment Horizons and Geomagnetic Field Excursions
AbstractThe relationship between spikes in cosmic dust fluxes onto the Earth’s surface (mainly represented by native metal particles) and the...

Reversals of the Geomagnetic Field: Constraint on Convection Intensity in the Earth’s Core
AbstractModern geodynamo models allow the generation of a magnetic field without reversals and with frequent reversals. The transition from one...

Influence of the Growth of Earth’s Solid Core on the Effective Geodynamo
AbstractA model of the Earth’s cooling, which describes the formation of a solid core, is considered. Its formation enhances the convection due to...

Evolution and Statistics of the Geomagnetic Energy and Its Characteristic Timescales Since 1840
The evolution of total (integrated from the core-mantle boundary to infinity) geomagnetic energy based on the COV-OBS.x1 geomagnetic field model is... -
Bicentennial Evolution and Statistics of Times of Variations in the Energy of the Potential Geomagnetic Field
AbstractThis paper examines two centuries of the evolution of the integral energy and power of the observed potential geomagnetic field. The research...

Electrical and thermal conductivity of Earth’s core and its thermal evolution—A review
The Earth’s core is composed of iron, nickel, and a small amount of light elements (e.g., Si, S, O, C, N, H and P). The thermal conductivities of...
