2011 Bi-Lateral Workshop Under the Sino-US Earthquake Studies Protocol

该奖项为将于2011年4月20日至25日在中国四川省成都市举行的中美地震研究协议双边研讨会提供支持。中国地震局（CEA）、国家自然科学基金（NSFC）中方和国家科学基金（NSF）地震研究科技合作协议，美国方面的美国地质调查局（USGS）于1980年1月首次签署，自那时以来，已延长了五年。 双方对议定书的价值予以肯定，认为议定书是两国间最成功的科技议定书之一。 议定书下的活动涵盖地震研究、地震工程和减灾以及数据交换的各个方面。该研讨会将是一系列研讨会中的第二个，旨在规划和发展科学合作所需的协调，以高效，有效和及时地向前推进。 这些讲习班的一个特别重点是促进数据、方法和软件的交流，培训学生，促进早期职业科学家的合作和交流。 研讨会旨在促进科学合作，包括美国和中国科学家之间的长期访问计划。 第二次研讨会的主题是什么？世纪大地震与地球动力学 世纪前十年的大地震已造成50多万人死亡，经济损失巨大。这些地震在构造环境和地球动力学过程方面各不相同，但在破裂过程和灾害情景方面也有一些共同特征。例如，与2008年汶川地震相关的复杂逆冲断层似乎与海地地震的走滑断层有很大不同。尽管震级较低，但海地7.0级地震造成的伤亡人数超过了汶川8.0级地震。2010年玉树地震发生在西藏内陆一个偏远、人烟稀少的地区，也造成了重大的人员和财产损失。对这些大地震的深入研究已经产生了丰富的观测数据，并对这些地震的地球动力学过程有了新的认识;这些研究的比较将有助于提高我们在未来大地震中减少地震损失的能力。

This award provides support for a bi-lateral workshop under the SINO-US protocol for earthquake studies to be held in Chengdu, Sichuan Province, China during the period April 20-25, 2011.The Protocol for Scientific and Technical Cooperation in Earthquake Studies among the Chinese Earthquake Administration (CEA), the National Natural Science Foundation (NSFC) on the Chinese side and the National Science Foundation (NSF), the U.S. Geological Survey (USGS) on the U.S. side was first signed in January, 1980 and has been extended in five year increments since then. Both sides have affirmed the value of the Protocol and consider it to be one of the most successful S&T protocols between the two countries. Activity under the Protocol covers various aspects of earthquake research, earthquake engineering and hazard mitigation and data exchange. The workshop will be the second one in a series that aims to plan and develop the coordination needed for scientific collaboration to move forward efficiently, effectively, and in a timely fashion. A particular focus of these workshops will be on promoting the exchange of data, methodology, and software, the training of students and fostering collaboration and exchange of early-career scientists. The workshop(s) will be designed to catalyze scientific collaborations, including plans for extended visits between US and Chinese scientists. The principal theme of this second workshop will be ?Great Earthquakes in the 21st Century and Geodynamics?. Great earthquakes during the first decade of the 21st century have killed more than 500,000 people and caused tremendous economic losses. These earthquakes differ from each other in terms of their tectonic environment and geodynamic processes, yet there are also some common features in both the rupturing processes and disaster scenarios. The complex thrust faulting associated with the 2008 Wenchuan earthquake, for example, appears to differ substantially from the strike-slip faulting of the Haiti earthquake. Despite its lower magnitude, the Mw 7.0 Haiti earthquake caused more casualties than the Ms 8.0 Wenchuan earthquake. The 2010 Yushu earthquake occurred in a remote and sparsely populated region of the interior of Tibet, but also caused significant human and property losses. Intensive studies following these great earthquakes have resulted in abundant observational data and new insights into the geodynamic processes of these earthquakes; comparisons of these studies will help to improve our ability to reduce seismic losses in future great earthquakes.
