The phenomena of slow slip, which includes slow slip events (SSE) and tectonic tremor (TT), have now been observed in nearly every subduction zone with dense geodetic and seismic networks and along some major crustal faults. Slow slip processes are now viewed by the seismological community as a crucial aspect of fault mechanics. Documents such as Seismological Grand Challenges in Understanding Earth?s Dynamic Systems and science plans for GeoPRISMS and EarthScope all point to the importance of studying slow slip. Previous conferences dedicated to slow slip have primarily focused on the Japan and Cascadia subduction zones. However new detailed studies in subduction zones in Alaska, Costa Rica, Mexico, New Zealand and fault zones such as the San Andreas and on faults beneath the Hawaiian volcano complex are providing additional observations. This Chapman Conference proposes to examine these phenomena globally and promote discussion and interaction by bringing together scientists working on Slow Slip in all places where they are observed. The slow slip community is now beginning to move beyond just observational studies, as many new datasets and modeling studies in the last few years have begun to shed light on the physical processes that produce slow slip. These recent efforts towards understanding process make this workshop even very timely. The conference will focus on the following topics:1) Observations of slow slip phenomena, 2) Fault structure and physical conditions where slow earthquakes are observed, 3) Slow earthquakes and their relationship to large earthquakes and seismic hazard, 4) Models and laboratory experiments, 5) Improving observational methods for the analysis of slow slip phenomena. The meeting will occur over 3 days. Its format will include oral presentations and posters. Participation in the conference will be open to anyone with an active interest in slow slip/slow earthquake processes. We will invite key speakers to provide the observations and structure from each subduction zone, as well as modeling, and laboratory experiments.

慢滑现象包括慢滑事件（SSE）和构造震颤（TT），在几乎每一个具有密集大地测量和地震台网的俯冲带和沿着一些主要地壳断裂都观测到了慢滑现象。现在，地震学界把缓慢滑动过程看作是断层力学的一个重要方面。《认识地球的地震学大挑战》（Seismological Grand Challenges in Understanding Earth）的动力系统和GeoPRISMS和EarthScope的科学计划都指出了研究慢滑的重要性。以前的会议致力于缓慢滑动主要集中在日本和卡斯卡迪亚俯冲带。然而，对阿拉斯加、哥斯达黎加、墨西哥、新西兰的俯冲带和圣安德烈亚斯等断层带以及夏威夷火山复合体下面的断层进行的新的详细研究提供了更多的观测结果。本次查普曼会议建议在全球范围内研究这些现象，并通过汇集在所有观察到这些现象的地方从事慢滑研究的科学家来促进讨论和互动。慢滑社区现在开始超越观测研究，因为过去几年中许多新的数据集和建模研究已经开始揭示产生慢滑的物理过程。最近为理解这一过程所做的努力使这次研讨会非常及时。本次会议的主要议题是：1）慢滑现象的观测; 2）慢地震观测的断层构造和物理条件; 3）慢地震及其与大地震和地震灾害的关系; 4）模型和实验室实验; 5）改进慢滑现象分析的观测方法。会议将持续3天。其形式将包括口头介绍和海报。任何对慢滑/慢地震过程感兴趣的人都可以参加会议。我们将邀请主要演讲者提供每个俯冲带的观测和结构，以及建模和实验室实验。
