1937年菏泽7级地震是中国近代地震史上具有特殊历史价值的地震:(1)菏泽地震的原始资料有4类载体:文字记载、震区"地震调查表"、地震波记录以及现场老照片,说明这次地震既有历史地震学属性,也有近代地震学属性,体现了中国历史地震学向近代地震学进展转化的时代特色。(2)由于抗日战争全面爆发等多方面原因,菏泽地震后政府基本没有实施有效的救灾行动,灾区陷于困难境地,只有上海华洋义赈会于震后一个月到灾区进行了有限的救助活动。菏泽地震是战争时期发生的灾难性地震,由此提示,在战时发生地震等严重自然灾害的应对问题应引起事先重视。 相似文献

以1995年珠江三角洲地区震害预测为基础，考虑近几年人口、建筑物的变化，综合给出了该区未来地震可能造成的人员伤亡情况。基于今后十年该区将处于较低的地震活动水平的估计，结合该区经济、地理条件和近几年世界上几次强震中人员伤亡的经验和教训，认为采取以下对策将大大减少未来地震可能造成的伤亡：①强化抗震设防要求，严格遵守抗震设计规范，提高建筑物的质量，杜绝劣质工程；②提高社会公众对于地震事件的心理承受能力；③建立完善的地震应急管理和救助机构。 相似文献

经验性的地震预测在中国地震预测研究与实践中 ,特别是在综合地震预测中 ,具有特殊的重要性 ,并将在今后的一段相当长的时间内继续发挥主要作用。人们越来越多地认识到 ,地震预测中一些经验和掌握这些经验的专家 ,是目前的计算机所无法取代的。一个挑战性的问题是 ,如何使这些经验变成可继承、可重复、可发展的知识体系。与此相应的 3个亟待解决的问题 :一是在地震机理仍不清楚的情况下 ,如何尽可能清楚地阐明一些经验的物理意义和统计显著性 ;二是如何使老一辈地震专家的经验更高效率地变成新一代地震专家的知识 ;三是如何就中国式的经验性… 相似文献

The patterns of temporal variations of precipitation (P), streamflow (SF) and baseflow (BF) as well as their nitrate-nitrogen (nitrate) concentrations (C) and loads (L) from a long-term record (28 years) in the Raccoon River, Iowa, were analyzed using variogram and spectral analyses. The daily P is random but scaling may exist in the daily SF and BF with a possible break point in the scaling at about 18 days and 45 days, respectively. The nitrate concentrations and loads are shown to have a half-year cycle while daily P, SF, and BF have a one-year cycle. Furthermore, there may be a low-frequency cycle of 6–8 years in C. The power spectra of C and L in both SF and BF exhibit fractal 1/f scaling with two characteristic frequencies of half-year and one-year, and are fitted well with the spectrum of the gamma distribution. The nitrate input to SF and BF at the Raccoon watershed seems likely to be a white noise process superimposed on another process with a half-year and one-year cycle. 相似文献

We rederive and generalize hyperbolic moveout formulae for the common-midpoint (CMP) gather and for the zero-offset (ZO) section that can be efficiently used for macro-model-independent reflection imaging in two-dimensional media. The hyperbolic moveout formulae for the common-midpoint gather are obtained from different Taylor series expansions of a particular parametric moveout surface defined in the multicoverage data space. Such a moveout surface involves three kinematic wave-field attributes of two hypothetical waves, which have to be determined by a coherency analysis. By using hyperbolic moveout curves in the CMP gather and in the ZO section one can determine these attributes in two steps. The relationships between the local shapes of the interfaces and the attributes of the hypothetical wave-fields attributes are considered by means of geometrical optics. The determination of these attributes allows to perform a macro-model-independent ZO simulation and a subsequent inversion. 相似文献

A close correlation in spatial distribution of local seismic activity and energy release patterns before and after the 1979 Petatlan, Mexico earthquake suggests heterogeneity within the fault plane of this major low-angle thrust event associated with subduction along the Middle America Trench. A simple two-asperity model is proposed to account for the complexity. Foreshocks and aftershocks of the neighboring 1981 Playa Azul earthquake showed a similar pattern. As both events occurred at the junction of the Orozco Fracture Zone and the Middle America Trench, we speculate that the observed complex fault plane is caused by subduction of the rugged ocean floor of the Orozco Fracture Zone. Short-term precursory seismicity prior to the Petatlan earthquake can be explained by using the asperity model and migration of a slip front from the south-east to the north-west across the main shock source region. 相似文献

Summary This paper discusses the influence of system stiffness on the dynamic instability of fault surfaces under laboratory conditions for a number of test modes. In conjunction with shear load stiffness, the normal load stiffness, often neglected, is shown to have a considerable effect on the stick-slip process —its presence or absence and its characteristics. Also appropriate stiffnesses are suggested for an earthquake sequence modeled as a growing dislocation. 相似文献
