  2010 AUG 17 - (VerticalNews.com) -- According to recent research published in the journal Physics of the Earth and Planetary Interiors, "We develop a quantitative and objective methodology for inversion of body-wave waveform data for elastic and anelastic structure and apply it to the upper mantle and mantle transition zone (MTZ) beneath the Northwestern Pacific, using PREM as the starting model. We use the singular value decomposition (SVD) as the basis for our inversion and use Akaike's Information Criterion (AIC) to evaluate the statistical significance of the models. ...read more

  2010 JUL 20 - (VerticalNews.com) -- According to a study from Russia, "The problem of identifying the effects of synchronization in the parameters of low-frequency microseismic noise from the data of 77 stations belonging to the F-net broadband seismograph network in Japan for the period from the beginning of 1997 through August, 2009 is considered. The vertical components measured initially with a sampling rate of one second and subsequently converted into the signals sampled at 1 minute intervals by means of averaging and decimation are used in the analysis. ...read more

  2010 JUL 20 - (VerticalNews.com) -- "The paper addresses the Late Cenozoic fault tectonics and the stress state of the Earth's crust within the Mongolian microplate, embracing Central and Western Mongolia. We analyze the results of reconstructing the stress fields and the tectonic deformations in the zones of active faulting, located at the uplands and in the intermountain trenches, which bound the microplate (Mongolian Altai; Gobi Altai; Dolinoozersk trough; Khan-Taishir-Nuruu, Khan-Houkhei, and Bolnai uplands) and the Khangai dome," investigators in Russia report ...read more
