The movement of the seawater across the earth's magnetic field produces a large-scale motional electric field. Using the Point Arena, California, to Hanauma Bay, Hawaii, unpowered HAW-1 cable, we have studied the geopotential across this distance to look for possible tsunami-induced fields that might have been produced following the April 1992 Cape Mendocino earthquake. We have used a ten-day interval prior to and including the earthquake as a reference for geopotential signals and for… 

Can undersea voltage measurements detect tsunamis?

The movement of electrically conducting ocean water in the ambient geomagnetic field induces secondary electric and magnetic fields in the oceans. Ocean water transport is now routinely inferred from

Studies of large-scale earth potentials across oceanic distances

Measurements of large-scale geoelectric potentials that can be induced within the Earth by fluctuations of the geomagnetic field can contribute important knowledge of the Earth's geophysical environment, as well as new geopotential information for engineering design.

Time–Frequency Characteristics of Tsunami Magnetic Signals from Four Pacific Ocean Events

The recent deployment of highly sensitive seafloor magnetometers coinciding with the deep solar minimum has provided excellent opportunities for observing tsunami electromagnetic signals. These

Motional Induction by Tsunamis and Ocean Tides: 10 Years of Progress

Motional induction is the process by which the motion of conductive seawater in the ambient geomagnetic main field generates electromagnetic (EM) variations, which are observable on land, at the

Solar Modal Structure of the Engineering Environment

In the attempt to understand this unexpected source of problems, it is found that solar modes are detectable in the interplanetary magnetic fields and energetic particles at the Ulysses spacecraft, five astronomical units from the Earth.

Tsunami Information Sources

I have expanded substantially my list of information sources on: tsunami generation (sources, impulsive mechanisms), propagation, effects of nearshore bathymetry, and wave run-up on shore - including

Lightning Discharges, Cosmic Rays and Climate

The entirety of the Earth’s climate system is continuously bombarded by cosmic rays and exhibits about 2000 thunderstorms active at any time of the day all over the globe. Any linkage among these

Ocean Observatories and Information: Building a Global Ocean Observing Network

Ocean observatories are collections of networks of sensors that are deployed to sample the ocean physics, chemistry, and biology. The goal of these networks is to overcome chronic undersampling of



Geoelectric field measurements on a planetary scale: Oceanographic and geophysical applications

The characteristics of an initial year of electric field measurements obtained from a long (=3900 krn), unpowered submarine cable extending from Point Arena, California, to Hanauma Bay, Hawaii are

Electromagnetic study of the Atlantic continental margin using a section of a transatlantic cable

The induction of currents in an approximately 1200 km length of the TAT-7 transatlantic telecommunications cable by geomagnetic field fluctuations is studied. Analyses of the induced voltage drop

Magnetic Signals from an Ocean Eddy

The movement of sea water in the magnetic field of Earth causes a process of motional electromagnetic induction. As a result, electric currents flow both in the sea water, and in the material of the

The variability in the volume transport of the Florida Current at 27°N has been observed from the voltage measured between a point 16 km east of Jupiter Inlet, Florida and Settlement Point, Grand

Observations of motional electromagnetic fields during EMSLAB

The long-period (>1 day) behavior of the seafloor electromagnetic fields during EMSLAB is considered in detail with an emphasis on interpretation in terms of oceanic motions. The study begins with a

The Cape Mendocino, California, Earthquakes of April 1992: Subduction at the Triple Junction

The 25 April 1992 magnitude 7.1 Cape Mendocino thrust earthquake demonstrated that the North America—Gorda plate boundary is seismogenic and illustrated hazards that could result from much larger

Observation and interpretation of the seafloor vertical electric field in the eastern North Pacific

A 37 day long recording of the seafloor vertical electric field collected on the East Pacific Rise and south of the mouth of the Gulf of California is examined. The principal barotropic ocean tides

Edge wave and non-trapped modes of the 25 april 1992 Cape Mendocino tsunami

The 25 April 1992 Cape Mendocino earthquake generated a tsunami characterized by both coastal trapped edge wave and non-trapped tsunami modes that propagated north and south along the U.S. West

Multivariate analysis of geomagnetic array data. 1 The response space

In this paper we develop a new approach to the multiple-station analysis of geomagnetic array data. Our approach is based on the observation that the space of external sources, and hence the space of
