-
(2004)It is now recognized that the earthquake hazard systems evolve naturally to the self-organized critical (SOC) state, in which the system is very sensitive to any external perturbations, and when the large avalanches (strong ...
-
(2000)Laboratory modeling showed that a macrofracture was preceded by typical acoustic emission phases. These are acoustic quiescence, gradual restriction of acoustic activity toward the future macrofracture location accompanied ...
-
(1999)Variations of several seismicity parameters during the precursory periods of large Kamchatka earthquakes of 1996-1997 were investigated. The successive phases of clustering, quiescence, and foreshock activity culminated ...
-
(2002)We investigated the characteristics of the precursory seismicity changes associated with the M=6.8 Nemuro Peninsula earthquake, January 28, 2000 by applying the RTL (Region–Time–Length) algorithm to the earthquake catalogue ...
-
(2001)The time series of annually averaged global surface temperature anomalies for the years 1856-1998 is studied through nonlinear time series analysis with the aim of estimating the predictability time. Detection of chaotic ...
-
(2002)A possible structure for hydrous modified olivine (HyM-α) has been obtained by the subtraction of Mg3SiO5 from forsterite by crystallographic shear along a direction parallel to the [010] direction of olivine. The subtraction ...
-
(1996)Theoretical predictions and measured isotope variations indicate that diet and physiological adaptation have a significant impact on animals δ18O and cannot be ignored. A generalized model is therefore developed for the ...
-
(2004)Flash floods are a common, but poorly understood feature of arid environments. Much of the uncertainty associated with flash flooding events is associated with a lack of accurate environmental data. In addition to limiting ...
-
(2003)Rapid preferential drainage or by-pass flow of water and pollutants occurs in soil macropores such as burrows and channels formed by earthworm activity in soils. We show that preferential flow through these non-capillary ...
-
(2002)The viscosity of volcanic melts at the glass transition has been determined for 11 compositions ranging from basanite to rhyolite. Determination of the temperature dependence of viscosity, together with the cooling rate ...
-
(2001)Sand-rich shoreline tongues are common features of the stratigraphic record, and many of them are important petroleum reservoirs. The basinward extent of such shallow-marine deposits is highly variable, from a few to a few ...
-
(2003)Major fault zones are surrounded by damage zones composed of minor faults that, in siliclastic rocks, often form significant barriers to fluid flow. Information on fault damage zone architecture is usually available only ...
-
(2003)Spatial crop yield prediction is an enigma that needs to be solved to avoid ecological and economical risks in agricultural crop production, that can result from local fertilizer surplus or deficiency. Current approaches ...
-
(2004)To investigate the effects of slope on the morphology of lava domes, laboratory experiments were conducted with a PEG-kaolin slurry erupted into cold water on slopes ranging from 0 to 60°. In each experiment the slope, ...
-
(2001)Prediction of overpressures [Abnormally High Formation Pressures (AHFP)] in the evaporite sequences is indeed a challenging problem. Several techniques are suggested here for the solution of this forecasting problem. For ...
-
(2005)Presented is an improved model for the prediction of phase equilibria and cage occupancy of CH4 and CO2 hydrate in aqueous systems. Different from most hydrate models that employ Kihara potential or Lennard-Jones potential ...
-
(2004)A method for the prediction of Gibbs free energies of formation for minerals belonging to the alunite family is proposed, based on an empirical parameter ΔGO= Mz+(c) characterizing the oxygen affinity of the cation Mz+. ...
-
(2002)A knowledge of the level of peak ground motion expected at a site from detonation of a known charge weight per delay at a specified distance is necessary for planning a safe blasting operation. The seismic wave energy ...
-
(2004)A new algorithm is suggested to assess in-field oil and gas reserves based on the size distribution of discoveries. The statistical performances of the estimators are tested through the Monte-Carlo imitation.
-
(2001)Post-mining drainage chemistry depends strongly on geochemical and hydrologic processes that occur during the operational years. Where routine operational monitoring data are abundant, the dominant processes can often be ...
