Electrical conductivity of old oceanic mantle in the northwestern Pacific I: 1-D profiles suggesting differences in thermal structure not predictable from a plate cooling model
Seafloor magnetotelluric (MT) experiments were recently conducted in two areas of the northwestern Pacific to investigate the nature of the old...

Adjoint tomography of the crust and upper mantle structure beneath the Kanto region using broadband seismograms
A three-dimensional seismic wave speed model in the Kanto region of Japan was developed using adjoint tomography for application in the effective...

A Reappraisal of Seismicity and Eruptions of Pantelleria Island and the Sicily Channel (Italy)
Three main tectonic depressions (the Pantelleria, Linosa and Malta troughs), the expression of a continental rift, characterize the Sicily Channel, a...

Mantle flow geometry from ridge to trench beneath the Gorda–Juan de Fuca plate system
Tectonic plates are underlain by a low-viscosity mantle layer, the asthenosphere. Asthenospheric flow may be induced by the overriding plate or by...

Aftershock observation of the 2003 Tokachi-oki earthquake by using dense ocean bottom seismometer network
The Tokachi-Oki earthquake occurred on September 26, 2003. Precise aftershock distribution is important to understand the mechanism of this...

Geographical distribution of shear wave anisotropy within marine sediments in the northwestern Pacific
In the northwestern Pacific, the elastic properties of marine sediments, including P- wave velocities ( Vp ) and S wave velocities ( Vs ), have recently...
-
Seismic Recorders
Seismic signals are analog and need to be recorded so they can be preserved and processed. The earlier recording was analog on paper, but now all...

P-wave velocity structure in the northern part of the central Japan Basin, Japan Sea with ocean bottom seismometers and airguns
In 1996, an airgun-ocean bottom seismometer survey was carried out in the northern part of the central Japan Basin. The crustal thickness in the...

Link between plate fabric, hydration and subduction zone seismicity in Alaska
Subduction zones worldwide exhibit remarkable variation in seismic activity over short distances of about tens of kilometres along their length. The...
