Separating polar ionospheric and lithospheric magnetic signals in satellite data [PDF]

, 2019
Both the interior of the Earth and near-Earth space contain a variety of interacting magnetic field sources, which together make up the “geomagnetic field”.

On the possible mantle nature of the long-wave Central-European magnetic anomaly

Геофизический журнал, 2020
This paper presents the results of a comprehensive analysis of geological and geophysical data, carried out to substantiate the existence and nature of transition class of magnetic anomalies produced by the Earth’s core and the lithosphere.

Analysis of the local lithospheric magnetic activity before and after Panzhihua M_w = 6.0 earthquake (30 August 2008, China) [PDF]

Natural Hazards and Earth System Sciences, 2011
Lithospheric ultra low frequency (ULF) magnetic activity is recently considered as a very promising candidate for application to short-time earthquake forecasting. However the intensity of the ULF lithospheric magnetic field is very weak and often masked

Satellite Measured Ionospheric Magnetic Field Variations over Natural Hazards Sites

Remote Sensing, 2021
Processes and threats related to natural hazards play an important role in the evolution of the Earth and in human history. The purpose of this study is to investigate magnetic field variations measured at low Earth orbit (LEO) altitudes possibly ...

Spatial-temporeral changes in the geomagnetic field and seismisity

Геофизический журнал, 2017
This paper presents the results of an analysis of spatial-temporeral changes in the Earth’s magnetic field and its seismicity for the period 1950—2015. The International Geomagnetic Field of the 12 generation (BIGRF-12) was analyzed.

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Geochemical investigation of impactites from the Boltysh impact structure and possible relationship to early Danian sediments from the Umbria–Marche Basin, Italy

Meteoritics &Planetary Science, EarlyView.
Abstract Within the Danian Scaglia Rossa Formation appears a regionally correlatable horizon cutting across multiple sections and outcrops within the Umbria–Marche Basin of NE Italy, where it is intercalated with uniform pelagic carbonate successions. This horizon is called “ALE layer” and has tentatively been interpreted as a fine‐grained volcanic ash.

Revised global vertically integrated remanent magnetization model of the oceanic lithosphere with comparison to LCS-1 model and MSS-1 magnetic measurements

Earth and Planetary Physics
The lithospheric magnetic field is an important component of the geomagnetic field, and the oceanic lithosphere exhibits distinct characteristics. Because of its formation mechanisms, evolutionary history, and geomagnetic field polarity reversals, the ...
