This project provides funding for international travel support to approximately early-career professionals and students to attend the Penrose Conference "Deformation, Fluid Flow and Mass Transfer along Convergent Margins" that will be held in Il Ciocco, Italy, from March, 26-30, 2012. The conference will explore recent developments related to deformation, fluid flow, and mass transfer in the forearc of convergent plate boundaries and their potential relationships to earthquake phenomena and seismogenesis. The objective of the conference is to consolidate recent advances in the understanding of convergent margins and to bring together researchers of different backgrounds to develop models for forearc evolution that explains observations of geometry, structure, deformation, and fluid flow at a variety of temporal and spatial scales. Forearcs are also the regions where energy release occurs in great tsunamigenic earthquakes, yet the links between earthquake-cycle deformation and longer-term geological structure, material properties, and the fluid regime remain obscure. The main topics at the meeting will include: (1) material balances - the processes and rates of accretion and erosion and their influence on seismogenesis; (2) interactions between the subducting and overriding plates including continental slope and forearc basins; (3) wedge dynamics and links between seismic and geologic time scales; (4) fluid flow in the forearc: evidence from direct observations and inferences from rock microstructures and geochemistry; and (5) the timescales of the earthquake cycle.This conference addresses many current research topics in tectonics and related fields. The conference affords international participants the opportunity to share recent research results and initiate new international research partnerships. The meeting provides an opportunity for integration of onshore and marine observations, experiments on mechanics and fluid flow, and results of geodynamic modeling to evaluate the relationship between these processes for plate boundary seismogenesis and hazards of the Pacific Rim - a topic of great concern for society as exemplified by the destructive event in northern Japan in March, 2011. Conveners will make efforts to broaden participation through support students and early career researchers from underrepresented groups in the earth sciences.

该项目为大约早期职业专业人士和学生提供了国际旅行支持的资金，将参加Penrose会议“沿融合利润率的变形，流体流量和质量转移”，该会议将于3月26日至30日在意大利IL Ciocco举行。 2012年。该会议将探讨与变形，流体流量和质量转移有关的最新发展，而收敛板边界的前臂及其与地震现象和地震发生的潜在关系。会议的目的是巩固对收敛边缘的理解的最新进展，并将不同背景的研究人员汇总为开发前进的模型，以解释在各种时间和空间上的几何观察，结构，变形和流体的观察结果秤。前牙前也是在大海啸中发生能量释放的区域，但是地震周期变形与长期地质结构，材料特性和流体状态之间的联系仍然晦涩难懂。会议上的主要主题将包括：（1）物质平衡 - 积聚和侵蚀的过程和速率及其对地震生成的影响； （2）俯冲和覆盖板之间的相互作用，包括大陆坡度和前臂盆地； （3）地震和地质时间尺度之间的楔形动力和联系； （4）前臂中的流体流量：来自岩石微观结构和地球化学的直接观察和推论的证据； （5）地震周期的时间表。此会议介绍了许多当前的构造和相关领域的研究主题。该会议为国际参与者提供了分享最新研究结果并启动新的国际研究合作伙伴关系的机会。这次会议提供了整合陆上和海洋观察的机会，有关力学和流体流动的实验以及地球动力学建模的结果，以评估这些过程之间的关系，以实现板界边界地震发生和太平洋危险的危害 - 对社会的极大关注的话题正如2011年3月在日本北部发生的破坏性活动所举例的。
