Jeffrey J. Love
I am a Research Geophysicist in the Geomagnetism Program of the U.S. Geological Survey (USGS). My research has encompassed a variety of subjects related to the Earth’s magnetic field.
These days, I work in collaboration with colleagues on three subjects: 1. Using geomagnetic monitoring data and magnetotelluric survey data to evaluate geoelectric hazards of concern to the electric-power grid industry. 2. Statistical analysis of the rare occurrences of extremely intense magnetic storms. 3. Analysis of historical records of past space-weather events and their impacts.
Research theme: Geomagnetic Hazards
Magnetic storms; Solar-terrestrial interaction; Magnetotellurics; Induced geoelectric fields; Space climatology; Geophysical monitoring; Rare, extreme, historical geophysical events; Earthquake prediction; Hypothesis testing; Time series analysis; Statistical analysis

On the lognormality of historical magnetic-storm intensity statistics: Implications for extreme-event probabilities On the lognormality of historical magnetic-storm intensity statistics: Implications for extreme-event probabilities
An examination is made of the hypothesis that the statistics of magnetic storm maximum intensities are the realization of a lognormal stochastic process. Weighted least squares and maximum likelihood methods are used to fit lognormal functions to −Dst storm time maxima for years 1957–2012; bootstrap analysis is used to established confidence limits on forecasts. Both methods provide fits...

On a report that the 2012 M 6.0 earthquake in Italy was predicted after seeing an unusual cloud formation On a report that the 2012 M 6.0 earthquake in Italy was predicted after seeing an unusual cloud formation
Several recently published reports have suggested that semi-stationary linear-cloud formations might be causally precursory to earthquakes. We examine the report of Guangmeng and Jie (2013), who claim to have predicted the 2012 M 6.0 earthquake in the Po Valley of northern Italy after seeing a satellite photograph (a digital image) showing a linear-cloud formation over the eastern...

Auroral omens of the American Civil War Auroral omens of the American Civil War
Aurorae are a splendid night-time sight: coruscations of green, purple, and red fluorescent light in the form of gently wafting ribbons, billowing curtains, and flashing rays. Mostly seen at high latitudes, in the north aurorae are often called the northern lights or aurora borealis, and, in the south, the southern lights or aurora australis. The mystery of their cause has historically...

Time causal operational estimation of electric fields induced in the Earth's lithosphere during magnetic storms Time causal operational estimation of electric fields induced in the Earth's lithosphere during magnetic storms
In support of projects for monitoring geomagnetic hazards for electric power grids, we develop a simple mathematical formalism, consistent with the time causality of deterministic physics, for estimating electric fields that are induced in the Earth's lithosphere during magnetic storms. For an idealized model of the lithosphere, an infinite half‐space having uniform electrical...

Magnetic storms and induction hazards Magnetic storms and induction hazards
Magnetic storms are potentially hazardous to the activities and technological infrastructure of modern civilization. This reality was dramatically demonstrated during the great magnetic storm of March 1989, when surface geoelectric fields, produced by the interaction of the time-varying geomagnetic field with the Earth's electrically conducting interior, coupled onto the overlying Hydro...

An international network of magnetic observatories An international network of magnetic observatories
Since its formation in the late 1980s, the International Real-Time Magnetic Observatory Network (INTERMAGNET), a voluntary consortium of geophysical institutes from around the world, has promoted the operation of magnetic observatories according to modern standards [eg. Rasson, 2007]. INTERMAGNET institutes have cooperatively developed infrastructure for data exchange and management ads...

Geomagnetic referencing--the real-time compass for directional drillers Geomagnetic referencing--the real-time compass for directional drillers
To pinpoint the location and direction of a wellborne, directional driller rely on measurements from accelerometers, magnetometer and gyroscopes. In the past, high-accuracy guidance methods required a halt in drilling to obtain directional measurements. Advances in geomagnetic referencing now allow companies to use real-time data acquired during drilling to accurately potion horizontal...

On the insignificance of Herschel's sunspot correlation On the insignificance of Herschel's sunspot correlation
We examine William Herschel's hypothesis that solar-cycle variation of the Sun's irradiance has a modulating effect on the Earth's climate and that this is, specifically, manifested as an anticorrelation between sunspot number and the market price of wheat. Since Herschel first proposed his hypothesis in 1801, it has been regarded with both interest and skepticism. Recently, reports have...

Insignificant solar-terrestrial triggering of earthquakes Insignificant solar-terrestrial triggering of earthquakes
We examine the claim that solar-terrestrial interaction, as measured by sunspots, solar wind velocity, and geomagnetic activity, might play a role in triggering earthquakes. We count the number of earthquakes having magnitudes that exceed chosen thresholds in calendar years, months, and days, and we order these counts by the corresponding rank of annual, monthly, and daily averages of...

The magnetic tides of Honolulu The magnetic tides of Honolulu
We review the phenomenon of time-stationary, periodic quiet-time geomagnetic tides. These are generated by the ionospheric and oceanic dynamos, and, to a lesser-extent, by the quiet-time magnetosphere, and they are affected by currents induced in the Earth's electrically conducting interior. We examine historical time series of hourly magnetic-vector measurements made at the Honolulu...

Problem of the Love‐Gannon relation between the asymmetric disturbance field and Dst Problem of the Love‐Gannon relation between the asymmetric disturbance field and Dst
Love and Gannon (2009) discovered that statistically, over a fifty year period the difference in the dawn and dusk disturbance‐field H component at low latitudes (hourly averaged) is linearly proportional to Dst. If the difference is designated by δDD in units of nT/RE, then the Love‐Gannon (L‐G) relation is δDD = −0.2 Dst. At any time departures from the relation can be large...
