Seismological aspects of the Guatemala Earthquake of February 4, 1976
Detailed analyses of teleseismic surface waves and body waves from the Guatemala e rthquake of February 4, 1976, show the following: (1) Left lateral displacement along a vertical fault with a strike varying from N66øE to N98øE is consistent with the teleseismic data. (2) The seismic moment was 2.6 X 102? dyn cm. The directivity ofthe surface wave radiation i dicates an asymmetric (1:2.3) bilat...
متن کاملGlobal Tectonic Regionalization for Seismological Data Analysis
A global tectonic regionalization, GTR1, has been constructed for use in seismological studies of aspherical heterogeneity. Three oceanic regions are defined by equal increments in the square root of crustal age (25and lO0-m.y. isochrons), and three continental regions are distinguished according to their generalized tectonic behavior during the Phanerozoic (Precambrian shields and platforms, P...

after the bolshevik revolution in 1917, he three transcaucasian republics (azerbaijan, armenia, georgia) were emerged.but because of the great powers' rivalry in transcaucasia, withholding of recognition of the republics by the allies in paris peace conference (1919), and the continuous conflicts between the republics themselves, the soviet :union: easily defeated the republics and annexed...
متن کاملModeling β Virginis using seismological data
This paper presents the modeling of the F9 V star β Virginis based on seismological measurements. Using the Geneva evolution code including rotation and atomic diffusion, we find that two distinct solutions reproduce all existing asteroseismic and non-asteroseismic observational constraints well: a main-sequence model with a mass of 1.28 ± 0.03 M⊙ and an age t = 3.24 ± 0.20 Gyr, or a model in t...
