The Wenchuan Earthquake

BackgroundThis presentation summarizes our ongoing hybrid sociological-geological research into China's earthquake disaster management systems. Our methodology is a grounded research approach, based firstly on field observations related to the Wenchuan earthquake, including interviews with survivors and professionals responsible for disaster management; secondly on an extensive review of the English-language disaster management literature. China's earth scientists, frequently in collaboration with international scientists, have created a substantial English-language literature, but the social literature on disasters in China is scant. China's geographic variation is complex, with significant fault lines criss-crossing the nation.DiscussionApproximately half of the population lives in areas with a high risk of earthquakes. The two most-devastating of these since 1949 were the 1976 point-source Tangshan earthquake with mortality of 242,419, and the 2008 huge-area Wenchuan earthquake with mortality of 69,226. Our research has found that China's earthquake disaster management systems at the local, provincial, and national levels respond rapidly to earthquakes. National mobilization for rescue-relief after the Tangshan earthquake began within six hours, and within two hours for the Wenchuan earthquake. These systems are also characterized by reconstruction planning that functions in parallel to, and melds into, the relief effort streams. China's major infrastructure projects, such as hydro-electric power dams, are designed to resist extreme earthquake; however, rural mountain populations and the historic built-environment have low earthquake resistance, conditions which will endure for a long time.ConclusionsAs a result of the Wenchuan earthquake, China has undertaken ambitious three-dimensional monitoring and response programs. We recommend studies and action to reconnoiter, investigate, and prevent population exposure to geo-hazards, particularly in the Qinghai-Tibet Plateau. In summary, China excels at disaster response but has not yet entered a development era of preventing the population's exposure to earthquake hazards.

Large Scale Project

After the WenChuan earthquake in may 12,2008,Many province government built the temporary houses for earthquake disaster area.For the first time, they initiate such large scale project, there are many problems emerged during the process of construction such problem like economy ,environment, engineering materials and technology. In this article, we collect problems and analysis them ,seek for the possible measures of construct the temporary house and the effective way to rebuilt the disaster area.

Stress Accumulation

On the Longmen Shan thrust belt (LMS) on the eastern margin of Tibet Plateau, the Mw7.9 Wenchuan earthquake occurred in 2008. As for the dynamic cause of the Wenchuan earthquake, many scholars have studied the rheological difference and terrain elevation difference on both sides of the fault. However, previous studies have simplified the LMS as a single listric-reverse fault. In fact, the LMS is composed of four faults with different dip angles in the shallow part, and the faults are Wenchuan-Maoxian fault (WMF), Yingxiu-Beichuan fault (YBF), Guanxian-Jiangyou fault (GJF) and Range Front Thrust (RFT) from west to east. However, the control of the branching structure of these faults on the distribution and accumulation of stress and strain during the seismogenic of the Wenchuan earthquake has not been discussed. In this paper, four viscoelastic finite element models with different fault numbers and combination structures are built to analyze the effect of fault branching structures on the stress distribution and accumulation during the seismogenic of Wenchuan earthquake, and we use geodetic data such as GPS and precise leveling data to constrain our models. At the same time, we also study the influence of the existence of the detachment layer, which is formed by the low-resistivity and low-velocity layer, between the upper and lower crust of the Bayan Har block and the change of its frontal edge position on the stress accumulation and distribution. The results show that the combinations of YBF and GJF is most conducive to the concentration of equivalent stress below the intersection of the two faults, and the accumulated stress on GJF is shallower than that on YBF, which means that more stress is transferred to the surface along GJF; and the existence of a detachment layer can effectively promote the accumulation of stress at the bottom of YBF and GJF, and the closer the frontal edge position of the detachment layer is to the LMS fault, the more favorable the stress accumulation is. Based on the magnitude of stress accumulation at the bottom of the intersection of YBF and GJF, we speculate that the frontal edge position of the detachment layer may cross YBF and expand eastward.

Public Concerns

AbstractThrough a review of the relevant literature from CNKI's Chinese Academic Periodical Internet Publication Database and its China Important Newspapers Database, this paper analyzes the coverage of the Wenzhou Earthquake. It answers the following questions: Did the reports following the disaster have any defining patterns or characteristics? What public concerns were reflected in the reports? Which spheres of society will feel the lasting effects of the earthquake? The goal of the essay is to discover what lessons can be drawn from the earthquake disaster and to understand systematically and holistically the significance of the earthquake for Chinese people.

Definition Of

This paper examines the role of knowledge management systems (KMS) for disaster planning and response in the context of social work in Malaysia. The research is focused on the client — the Malaysian Association of Social Workers (MASW), where a web-based system to support disaster management was developed and implemented. The research objectives required the researchers' direct involvement with the MASW. Canonical Action Research (CAR) was used as the research methodology. The process and outcomes of this action research initiative is presented based on the five-stage CAR approach, consisting of (i) problem diagnosis, (ii) action planning, (iii) intervention, (iv) evaluation and (v) learning outcomes. The evaluation of the system is supported by quantitative analysis driven by survey instrumentation. Our findings suggests that successful utilisation of the system in the context of MASW's efforts and roles in disaster management in Malaysia, is contingent upon issues such as acceptance of KMS, and availability of resources to maintain the system. Other issues such as clear definition of the role of Information Technology (IT) for disaster management and willingness to share knowledge are also vital in this regard.
