The ThellierTool4.0 is an intuitive and easy‐to‐use software which provides the possibility to analyze a wide range of different modifications Thellier absolute paleointensity experiment (available at http://earthref.org/tools/ ). Besides Arai plot for determination, orthogonal projections direction, decay NRM during thermal demagnetization, additional plots regarding alteration multidomain checks enable user visualize quality individual determinations. Experimental magnetomineralogical...
Records of the past geomagnetic field can be divided into two main categories. These are instrumental historical observations on one hand, and estimates based magnetization acquired by rocks, sediments archaeological artefacts other hand. In this paper, a new database combining historical, archaeomagnetic volcanic records is presented. HISTMAG relational database, implemented in MySQL, accessed via web-based interface...
Abstract. Geomagnetically induced currents (GICs) in power systems, which can lead to transformer damage over the short and long term, are a result of space weather events geomagnetic variations. For time, only high-latitude areas were considered be at risk from these currents, but recent studies show that considerable GICs also appear midlatitude equatorial countries. In this paper, we present initial results GIC model using thin-sheet approach with detailed surface subsurface conductivity...
Abstract Space weather events can cause geomagnetically induced currents (GICs) in power transmission networks. Over the past years, these have been measured multiple substations Austria, and measurements tested against a model of local GIC with aim producing an optimized model, which be developed through evaluation various input parameters. We show impact choice resistivity, particular surface conductivity thin‐sheet modeling, source geomagnetic variations has on modeling. In addition,...
The study of geomagnetic field variations provides information on the Earth's inner dynamics, helps understanding role magnetic as primary shield against cosmic radiations and is also used a geochronological tool for dating archaeological artefacts. Geomagnetic during Early Medieval Age (EMA) in Central Europe are generally poorly constrained due to scarcity sites. While rapid intensity increase 6th century, along with high values 7th 9th centuries, have been reported Western Europe, new...
The Mur-Mürz fault line is an active boundary between the geological units of Eastern Alps and Pannonian basin. Some moderate earthquakes shake this densely inhabited border area Austria Hungary every year, consequently special attention paid for research its seismo-tectonic activity. Beyond seismological monitoring continuous observation long periodic crustal deformations may efficiently help understanding interpretation mechanism tectonic processes connected to events. Therefore, in...
Since April 2024 the Conrad observatory, located 60 km SW of Vienna within a karstic area Eastern Alps (Austria), operates superconducting iGrav gravimeter (iGrav050) continuing previous more than 10 years long gravity time series GWR C025. Their residuals indicated an extremely complex local hydrology in surroundings observatory. For better understanding hydrological processes geoelectric profile has been installed which monitors 2D resistivity section each day. The runs across topography...
The global paleointensity database is restricted by the high failure rate of analyses. Excluding thermal alteration, usually caused presence multidomain grains and interactions among grains, two properties that can be identified using first‐order reversal curve (FORC) diagrams. We measured FORC diagrams on sister samples about 200 had been used for Thellier determinations determined criteria to discriminate gave acceptable results from those did not. three most discriminating are vertical...
The forecasting of local GIC effects has largely relied on the dB/dt as a proxy and, to date, little attention been paid directly geoelectric field or GICs themselves. We approach this problem with machine learning tools, specifically recurrent neural networks LSTMs by taking solar wind observations input and training models predict two different kinds output: first, components Ex Ey; second, in specific substations Austria. is carried out modelled from 26 years one-minute geomagnetic...
Abstract. Lava dome eruptions subjected to high extrusion rates commonly evolve from endogenous exogenous growth and limits their structural stability hold catastrophic potential as explosive eruption triggers. In the conduit, strain localisation in magma, accompanied by seismogenic failure, marks onset of brittle magma ascent dynamics. The rock record structures preserves vestiges cataclastic processes thermal anomalies, key unravelling subsurface processes. Here, a combined structural,...
It is widely accepted that cooling rate can strongly influence the intensity of thermal remanent magnetization (TRM) acquired by rocks during to ambient temperatures. If ignored, this effect might lead underestimates or overestimates ancient magnetic field intensity. To date, however, dependence TRM particles with different domain states has never been systematically analyzed from theoretical experimental point view. In study, we present measurements synthetic magnetites well‐defined grain...
