Slip Distribution of the 19 September 1985 Michoacan , Mexico , Earthquake : near - Source and Teleseismic Constraints
We simultaneously invert the strong-motion velocity records and the longand intermediate-period teleseismic P waveforms of the 19 September 1985 Michoacan, Mexico, earthquake to recover the distribution of slip on the fault using a point-by-point constrained and stabilized, least-squares inversion method. A fault plane with strike fixed at 300 ° and dip fixed at 14 ° is placed in the region of ...
متن کاملFactors Contributing to the Catastrophe in Mexico City during the Earthquake of September 19 , 1985
The extensive damage to high-rise buildings in Mexico City during the September 19, 1985 earthquake is primarily due to the intensity of the ground shaking exceeding what was previously considered credible for the city by Mexican engineers. There were two major factors contributing to the catastrophe, resonance in the sediments of an ancient lake that once existed in the Valley of Mexico, and t...
متن کاملCharacteristics of the 1985 Michoacan
Source characteristics of the Sept. 19, 1985 Michoacan, Mexico earthquake and its aftershock on Sept. 21 were inferred from broadband and short-period teleseismic GDSN records. We Fourier-transformed the P waves, corrected for instrument response, attenuation, geometrical spreading, and radiation pattern (including the depth phases), and then averaged to obtain the teleseismic source spectrum f...

متن کاملSource Characteristics of Earthquakes in the Michoacan Seismic Gap in Mexico by Luciana Astiz, Hiroo Kanamori, and Holly Eissler
We investigated the source characteristics of large earthquakes which occurred in the Michoacan, Mexico, seismic gap during the period from 1981 to 1986 in relation to historical seismicity in the region. The rupture pattern of the Michoacan gap during this period can be characterized by a sequential failure of five distinct asperities. Before 1981, the Michoacan gap had not experienced a large...
