20世纪长江的3次巨洪

分析了形成20世纪长江3次巨洪的3个遥相关因子：（1）太阳黑子活动;（2）厄尔尼诺事件,（3）青藏高原南部大震。依据长江巨洪和遥相关因子的基本事实,讨论了长江发生巨洪的统计规律。指出当3个因子的出现时间互相重叠时,长江很可能发生巨洪,这对长江巨洪的超长期预测具有重要的指导作用。     

江苏数字地震台网地震定位能力分析

依据江苏数字地震台网的几何布局 ,对区域上设定的不同震级和震源位置的可能事件 ,作了以下两点考虑。 (1)根据不同震级地震的监测范围 ,确定了相应的定位子台组合。 (2 )对同一地震事件 ,考虑到震相分析P震相和S震相测量精度上的差异 ,引入了不同的标准误差σP 和σS。在此基础上 ,通过模拟地震波理论走时和对走时矩阵的奇异值分解方法 ,计算了估计震源参数标准误差的参量空间协方差矩阵值 ,给出了标准误差理论值等值线图 ,用此方法讨论分析了江苏数字地震台网的地震定位能力。

六安流动地磁测量异常的映震能力探讨

将安徽省六安地区流动地磁测线 12个流动地磁测点的∑ |δfi|异常与安徽中西部地震活动性作对比分析 ,初步结果为 :12个流动地磁测点的∑ |δfi|值较大 (∑ |δfi|≥Fu) ,一年内安徽中西部地区的地震活动性增强 ;反之 ,则安徽中西部地区的地震活动性较弱。此方法在地震的中短期预报中有一定的实用意义。     

利辛M4.1地震前的流磁异常及其变化

安徽省利辛县张村镇 1 999 1 2 3 0发生M4 1地震 ,震前数日省流磁测量组在皖北进行了 1 999年第 4期流动地磁测量。运用Sδf方法分析此期流磁资料 ,可见明显异常。震后 ,异常恢复。分析认为 :Sδf方法在运用流磁资料作短期地震预报方面具有一定实用性。     

Are we planning for sustainable disaster recovery? Evaluating recovery plans after the Wenchuan earthquake

This article examines local recovery plans that were created in response to the Wenchuan earthquake and then suggests ways that planners can better apply the concept of sustainability to the recovery process. We utilize a plan evaluation protocol to analyze 16 recovery plans in counties and towns that were severely affected by the earthquake. We also conducted semi-structured interviews with public officials and planners, with the qualitative data gleaned from these interviews being used to supplement the plan quality assessment. The results reveal that local recovery plans do not appear to have incorporated sufficiently the concepts of sustainability. We conclude the paper with the following recommendations: emphasizing sustainability as a policy priority during vision and goal development; developing solid databases and planning techniques; designing a diversified set of regulatory- and incentive-based policy tools suitable for local governments; enhancing social and institutional learning; and further integrating multi-level and interagency governmental units.     

Communicating risk for vulnerable groups: a case study of the Mano community’s strategies for collective knowledge to action

This paper discusses the emergent interest in risk communication as a strategy for disaster risk reduction. Communication plays an essential role in understanding risk, but studies suggest that people often do not respond in the way that risk experts anticipate. For risk communication to be effective, vulnerable communities need to understand risk within the local context as well as in terms of sustainability. Risk messages offer communities a way to enhance their collective knowledge of existing vulnerabilities, leading them towards alternative solutions for action. A longitudinal study of the Mano community development approach and its recovery from the 1995 Kobe earthquake illustrates how risk communication dynamics contributed to the community’s sustainable risk reduction. The study concludes that risk communication is a collaborative way for a community to work with risk experts, own their risk information, influence existing policies and practices, develop solutions to reduce vulnerability, and ultimately enhance a community’s capacity for managing future risk.     

汶川大地震灾后青少年心理援助经验启示

为探索和创新汶川大地震以及其他灾情灾后青少年心理援助提供科学决策依据,通过对四川灾区民众的调查分析及其对收集的信息资料研究,着重揭示了汶川大地震灾后青少年心理援助的经验：“三个加强”——加强方式、方法、机制“三位一体”对青少年心理援助,“三个强化”——社会、学校、家庭“三位一体”对青少年心理援助的启示。     

农村家庭认知与响应地震灾害的特点及其家庭际差异——以2007年云南宁洱6.4级地震灾区为例

以2007年云南宁洱6.4级地震灾区为例,通过现场访谈和问卷调查,分析了该地区农村家庭认知与响应地震灾害的特点及其家庭际的差异性。结果表明:当地农村家庭认知与响应地震灾害的水平尚不理想,综合防震减灾能力较弱;家庭对地震灾害知识和防震减灾技能的掌握程度,显著地影响着其在震时及震后的响应行为和态度,其中防震减灾技能的影响更显著;经济收入和教育背景不同的家庭,其地震灾害的认知水平和响应能力也呈现出明显的差异性,其中受教育程度的影响更明显,且可能是最根本的影响因素;家庭人口总数与家庭地震灾害认知与响应的综合能力呈显著的负相关关系,但这种影响也叠加了家庭经济文化因素的影响;对研究区而言,加强防震减灾实用技能和震时如何有效应对地震影响方面的教育,具有更重要的现实意义。
