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 کاملThe 1992 Landers Earthquake Sequence: Seismological Observations
The (Mw6.1, 7.3, 6.2) 1992 Landers earthquakes began on April 23 with the Mw6.1 1992 Joshua Tree preshock and form the most substantial earthquake sequence to occur in California in the last 40 years. This sequence ruptured almost 100 km of both surficial and concealed faults and caused aftershocks over an area 100 km wide by 180 km long. The faulting was predominantly strike slip and three mai...
متن کاملSeismological Aspects of the December 2004 Great Sumatra-Andaman Earthquake
The 2004 Great Sumatra-Andaman earthquake had an average source duration of about 500 sec. and a rupture length of 1 ,200–1,300 km. The seismic moment, M0, determined with a finite source model, was 6.5 1022 N-m, which corresponds to Mw=9.18. Allowing for the uncertainties in the current M0 determinations, Mw is in the range of 9.1 to 9.3. The tsunami magnitude Mt is 9.1, suggesting that the ov...
متن کاملon translation of politeness strategies in dialogues involving female characters in translations and retranslations of novels translated before and after the islamic revolution of iran and their effects on the image of women: a polysystem theory approach
abstract reception environment has considerable effects on accepting a translation. as the expectations of a target culture and its values and needs change throughout history, its criteria for accepting a translation or rejecting it will change accordingly (gentzler, 2001). the expectations of iran, as the reception environment in the present study, have changed after the islamic revolution. i...
Estimation of the Maximum Earthquake Magnitude, mmax
This paper provides a generic equation for the evaluation of the maximum earthquake magnitude mmax for a given seismogenic zone or entire region. The equation is capable of generating solutions in different forms, depending on the assumptions of the statistical distribution model and/or the available information regarding past seismicity. It includes the cases (i) when earthquake magnitudes are...
