A new approach to earthquake precursors distinction

open access: yesГеофизический журнал, 2012
A lithospheric ultra low frequency (ULF) magnetic activity is recently considered as very promising candidate for application to short-time earthquake (EQ) forecasting.

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

open access: yesNatural 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

Bayesian inversion for the filtered flow at the Earth's Core Mantle Boundary

open access: yes, 2013
The inverse problem which consists of determining the flow at the Earth's Core Mantle Boundary according to an outer core magnetic field and secular variation model, has been investigated through a Bayesian formalism. To circumvent the issue arising from

Crustal structure and rift flank uplift of the Adare Trough, Antarctica [PDF]

open access: yes, 2005
The Adare Trough, located 100 km northeast of Cape Adare, Antarctica, represents the extinct third arm of a Tertiary spreading ridge between East and West Antarctica. It is characterized by pronounced asymmetric rift flanks elevated up to over 2 km above

The Magnetic Field of the Earth's Lithosphere: The Satellite Perspective [PDF]

open access: yesEos, Transactions American Geophysical Union, 1999
During the planning stages of the World Magnetic Survey in the early 1960s, geologists and geophysicists had no inkling that crustal magnetic anomalies might one day be observed from space. The appearance of The Magnetic Field of the Earth's Lithosphere: The Satellite Perspective is a welcome testimony to how far that science has advanced.

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

open access: yesГеофизический 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.

A 2D Lithospheric Magnetic Anomaly Field over Egypt Using Gradient Data of Swarm Mission

open access: yesUniverse, 2022
The current work makes use of the geometrical configuration of the two lower-altitude Swarm satellites (Swarm A and C), moving side by side with a longitudinal distance of 1.4°, to estimate a two-dimensional (2D) model of the lithospheric magnetic ...

Spatial-temporeral changes in the geomagnetic field and seismisity

open access: yesГеофизический 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.

Satellite Measured Ionospheric Magnetic Field Variations over Natural Hazards Sites

open access: yesRemote 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 ...
