TL;DR: In this article, the relation between thermal anomalies and seismic activity was established for Middle Asia on the basis of a 7-year series of thermal images, and the analysis of digital images for Japan shows the following: (a) the anomaly appears 7-10 days before shock; (b) the anomalies in Japan have small size; (c) probably, thermal anomaly is located in Kanto area and the magnitude of anomaly run up to 6°C; (d) the tectonic position of anomalies is not clear now.

TL;DR: In this article, it was shown that when dry gabbro and diorite cores are impacted at relatively low velocities, approximately 100 m/s, highly mobile charge carriers are generated in a small volume near the impact point.

TL;DR: In this article, the authors proposed three satellite missions, starting with CHAMP in 2000, followed by GRACE in 2002 and GOCE in 2004, which have a wide range of applications in solid Earth physics, oceanography, ice research, geodesy and sea level research.

TL;DR: In this article, the authors used a NASA P-3 aircraft to estimate the surface elevation of the Greenland ice sheet using a scanning laser, which was positioned by differential GPS and flown approximately 500 m above the surface.

TL;DR: A database of 304 possible large igneous provinces (LIPs) extending back to 3.8 Ga is used to explore the maximum size and distribution in time and space of large mantle plume heads as mentioned in this paper.

TL;DR: In this paper, anomalous electromagnetic phenomena at varied frequency ranges, covering ELF to VHF, have been reported in relation to the 17 January 1995 Kobe earthquake (M7.2), by several independent research groups.

TL;DR: In this paper, the authors proposed that during mid-Cretaceous, the weak crust of the Mississippi Valley graben complex was uplifted 1-3 km as it passed over the Bermuda plume, and this upland was eroded.

TL;DR: The age and rock type, regional distribution and structural setting of volcanic and plutonic manifestations from the western Mediterranean basin and peripheral orogens during the past 30 Ma are examined in this paper.

TL;DR: In this paper, the surface area of the smallest oceanic plateau generated during the Cretaceous superplume era was used to define the characteristics of plume events that can be called superplumes.

TL;DR: In this article, the authors investigated the utility of the lidar technique for making sub-canopy topography measurements, the precision and accuracy of the LVIS elevation measurements from this mission are assessed.

TL;DR: In this article, a review of available geological and geophysical data has been integrated by the analysis of seismic reflection lines calibrated with deep well logs, showing that active thrusting and related folding in the study area ceased in Early Pleistocene times.

TL;DR: In this article, two available seismic sections across the Eastern Ghats mobile belt (EGMB) and the Cuddapah basin have been integrated with the modelling of Bouguer anomalies along these profiles.

TL;DR: In this paper, a rheologically, thermally and dynamically consistent convection technique was used to model the crustal evolution related to delamination and detachment of the lithospheric mantle under a crustal root.

TL;DR: DEMETER as discussed by the authors is a micro-satellite (110 kg) with a low-altitude (<800 km) and a nearly polar orbit, whose scientific objectives are related to the investigation of the ionospheric perturbations due to the seismic activity, and to the global study of the Earth electromagnetic environment.

TL;DR: In this paper, a plume starting head possibly situated marginally to the Kaapvaal craton is inferred for this unit of up to 2 km of predominantly tholeiitic basalts with subordinate, basal komatiites.

TL;DR: In this article, two tectonic wedges are distinguishible in three areas of the Southern Apennines (Lucanian sector) selected for the present study, both characterized by compressive deformation tied up to a thin-skinned tectonics context, and the more ancient accretionary wedge (Late Oligocene-Early Miocene) is connected with the subduction of the Tethys oceanic crust (Liguride/Sicilide Units) which stopped at the collision between the European margin and the Maghrebide crust.

TL;DR: Aptian-Albian carbon isotope records of marine carbonate, marine organic carbon, and terrestrially photosynthesized carbon as a 3-5% negative excursion were recorded in the early Aptian (ca. 117 Ma) CO 2 clathrates as mentioned in this paper.

TL;DR: The growth of juvenile continental crust during a possible superplume event at 1.9-Ga occurred mainly in the form of new arc systems (esp. continental-margin arcs), which were accreted to cratons during supercontinent formation at 1880-1840 Ma as mentioned in this paper.

TL;DR: The Mura-Zala Basin was formed due to ENE-WSW trending crustal extension in the late Early Miocene (18.3-16.5 Ma) as discussed by the authors.

TL;DR: In this article, the authors used published data for the Phanerozoic, Proterozoic and Archean in order to check whether there had been significant long-term changes of geomagnetic intensity.

TL;DR: In this paper, a model of an earthquake hypocenter zone in which the electrokinetic current results from fluid filtration in a fractal pore network is considered, and a critical exponent of the streaming potential coefficient is found to depend on both the transport critical exponent and correlation length critical exponent.

TL;DR: In this article, a map of the modal values using a grid space of 3 × 3 was generated for 27 different seismic regions in terms of tectonic environments using the least-squares method.

TL;DR: A petrographic and geochemical study of 15 Early Jurassic and 7 Proterozoic dolerites of French Guyana, and of one Jurassic dolerite from Ivory Coast were carried out as mentioned in this paper.

TL;DR: In this article, a new and updated interpretation of the gravity map of the eastern part of the Pyrenean belt based on the well-established correlation existing between gravity anomalies and crustal structure is proposed.

TL;DR: In this article, a recently proposed predictive parameter of region-time-length (RTL) was tested using the seismological catalogues of Kamchatka (Russia) and Japan Meteorological Agency (JMA).

TL;DR: In this paper, the magnetic field components near the outcrop of an almost horizontal (elongated) conductive sheet when an electric dipole lies far away from an outcrop but close to the sheet were studied.

TL;DR: The return pulse correlation method as discussed by the authors maximizes the shape similarity of coincident laser return waveforms from two observation epochs by shifting them vertically, which can improve the accuracy of surface change estimates made using laser altimeter waveforms, especially beneath vegetation.

TL;DR: In this article, the authors analyzed the greatest plasma frequency, foF2, observed by the Chung-Li ionosonde (25.0°N, 121.l°E) during the period of the Chi-Chi and Chia-Yi earthquakes.

TL;DR: The Euler and the analytic signal methods have been implemented in spherical coordinates to facilitate the interpretation of spherically-registered potential-field anomaly data collected by satellites as discussed by the authors, however, the depth resolution is not adequate from this altitude.
