Geothermal Resource Exploration, Naf El Centro – Superstition Mountain Area, Imperial Valley, California
The geothermal potential of West Mesa has historically been assumed to be small because it is thought to be dominated by a left-stepping transpressional regime that is generally tight and not conducive to open fluid pathways. This may not be the complete picture, however. The 85 MWe Heber geothermal project appears to be located in a right stepover from the northwest trending seismogenic extens...
متن کاملCOMPLEXITY OF ENERGY RELEASE DURING THE IMPERIAL VALLEY, CALIFORNIA, EARTHQUAKE OF 1940 BY MmA1LO D. TRIFUNAC AND JAMES
The pattern of energy release during the Imperial Valley, California, earthquake of 1940 is studied by analyzing the El Centro strong motion seismograph record and records from the Tinemaha seismograph station, 546 km from the epicenter. The earthquake was a multiple event sequence with at least 4 events recorded at El Centro in the first 25 seconds, followed by 9 events recorded in the next 5 ...
متن کاملStrong Motion Data Processing and Recording at University of Southern California
A brief review is presented of the Los Angeles and Vicinity Strong Motion Network operated by the University of Southern California (USC), consisting of 80 stations deployed in 1978-1980, and of software developed and used at USC for digitization of accelerograms recorded on film, and for routine and specialized data processing of digitized or digitally recorded accelerograms. The currently use...
متن کاملNonlinearity at California Generic Soil Sites from Modeling Recent Strong-Motion Data
The average strongto weak-motion amplification ratios during the 1989 Loma Prieta and 1987 Whittier Narrows earthquakes in California are estimated by modeling strong ground motions at soil sites in the linear-response assumption and comparing the simulated and observed records. The linear amplification function, used to synthesize ground motions, is the generic transfer function developed for ...
متن کاملa generalization of strong causality
در این رساله t_n - علیت قوی تعریف می شود. این رده ها در جدول علیت فضا- زمان بین علیت پایدار و علیت قوی قرار دارند. یک قضیه برای رده بندی آنها ثابت می شود و t_n- علیت قوی با رده های علی کارتر مقایسه می شود. همچنین ثابت می شود که علیت فشرده پایدار از t_n - علیت قوی نتیجه می شود. بعلاوه به بررسی رابطه نظریه دامنه ها با نسبیت عام می پردازیم و ثابت می کنیم که نوع خاصی از فضا- زمان های علی پایدار, ب...
