Microearthquake studies in Egypt carried out by the geological survey of Egypt     

Fouad K. Boulos  Paul Morgan  Tousson R. Toppozada 《Journal of Geodynamics》1987,7(3-4)

Extensive microearthquake studies have been conducted in Egypt as a joint project between scientists from the Egyptian Geological Survey and Mining Authority (EGSMA) and U.S. scientists. At this stage, a great part of the data has been analyzed and two intensively active areas have been located: one in the Abu Dabbab area of the Eastern Desert, the second at the mouth of the Gulf of Suez near Gubal Island (Daggett et al., 1980). Both sites have been reported to be the epicenters of large earthquakes in 1955 and 1969, respectively. A few scattered earthquakes have also been located in the northern part of the Red Sea, some of which lie along its median axis (Daggett et al., 1986) adding to evidence for the medial opening of the northern Red Sea. After the occurrence of an earthquake (M = 5.5) in the Aswan region on 14 November 1981, continuous recording of the many aftershocks was carried out by EGSMA for about seven months from December 1981 to July 1982, when the temporary network was replaced by a network of telemetered seismographs installed and operated by Helwan Institute of Astronomy and Geophysics in cooperation with scientists from Lamont and Doherty Geological Observatory (LDGO). The majority of epicenters are concentrated in the vicinity of G. Marawa about 65 km upstream of Aswan Dam, along the E-W Kalabsha fault. The observed focal mechanism is consistent with a right-lateral strike-slip motion on the Kalabsha fault. Analysis of Aswan microearthquakes has been done by EGSMA in cooperation with scientists from California Division of Mines and Geology (CDMG).  相似文献   

The role of women peasants in the process of desertification in Western Sudan     

Fouad N. Ibrahim 《GeoJournal》1982,6(1):25-30

Women peasants in the Sudan are both agents of and sufferers from the process of desertification which is taking place in the arid and semi-arid zone. The researchwork done by the author on the problem of desertification in the west of the Republic of the Sudan convinced him that women there suffer much more than men do from the decrease of land productivity. Paradoxically enough, women themselves have actively taken part in desertifying their environment in their desperate attempt to keep their families living. This paper endeavours to highlight the role of peasant women in areas prone to or already stricken by desertification. Especially in the transitional phases following drought disasters and loss of live-stock the whole brunt of catering for the family falls on the shoulders of peasant women. Three main issues are being tackled: Millet production as essentially women's task, rainfall variability and its impact on women cultivators, the settlement of nomads and semi-nomads as a new burden laid on women. Finally, some suggestions are made to improve the conditions of women's work to provide nutrition for their families without doing much destruction to the fragile environment and its limited resources.  相似文献
