Revisiting magnetotelluric theory: layered induction and geoelectric fields
Dennies Bor
We review the magnetotelluric (MT) theory of a horizontally layered Earth under plane wave forcing and its use in calculating geoelectric fields. Starting from Maxwell's equations,…
A Comparative Multi-Hazard Risk Assessment of the US High-Voltage Transmission Network
D. Bor, E. J. Oughton, R. S. Weigel +4
Modern economies depend critically on high-voltage power transmission networks. Yet this infrastructure is routinely disrupted by natural hazards ranging from earthquakes and flood…
C-SWIM: A Coupled Space Weather Impact Model for Satellite Fleet Vulnerability and Economic Loss Under a 1-in-100-Year Solar Energetic Particle Event
D. Bor, E. J. Oughton, R. S. Weigel +4
Modern economies depend critically on satellite infrastructure, yet the aggregate economic consequences of extreme solar energetic particle (SEP) events have not been rigorously as…
Comparing Object Detection Models for Electrical Substation Component Mapping
Haley Mody, Namish Bansal, Dennies Kiprono Bor +2
Electrical substations are a significant component of an electrical grid. Indeed, the assets at these substations (e.g., transformers) are vulnerable to hazards such as hurricanes,…
Assessing the economic benefits of space weather mitigation investment decisions: Evidence from Aotearoa New Zealand
Edward J. Oughton, Andrew Renton, Daniel Mac Marnus +2
Space weather events pose a growing threat to modern economies, yet their macroeconomic consequences remain underexplored. This study presents the first dedicated economic assessme…
Major Space Weather Risks Identified via Coupled Physics-Engineering-Economic Modeling
Edward J. Oughton, Dennies K. Bor, Robert Weigel +5
Space weather poses an important but under-quantified threat to society. While severe geomagnetic storms are recognized as potential global catastrophes, their socio-economic impac…
A Reproducible Method for Mapping Electricity Transmission Infrastructure for Space Weather Risk Assessment
Dennies K. Bor, Edward J. Oughton, Evan A. Peters +4
Space weather risk assessment is constrained by the lack of available asset information needed to model geomagnetically induced currents (GICs) in electricity transmission infrastr…
Quantifying polarization across political groups on key policy issues using sentiment analysis
Dennies Bor, Benjamin Seiyon Lee, Edward J. Oughton
There is growing concern that over the past decade, industrialized democratic nations are becoming increasingly politically polarized. Indeed, elections in the US, UK, France, and…
