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.

慢滑动现象，包括慢滑动事件（SSE）和构造震颤（TT），现在几乎在每个具有密集大地测量和地震网络的俯冲带以及沿着一些主要地壳断层都被观察到。慢滑动过程现在被地震学界视为断层力学的一个重要方面。 《理解地球动态系统的地震学重大挑战》等文件以及 GeoPRISMS 和 EarthScope 的科学计划都指出了研究慢滑移的重要性。之前专门讨论慢滑移的会议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断层带以及夏威夷火山群下方断层的新的详细研究提供了额外的观察结果。这次查普曼会议提议在全球范围内研究这些现象，并通过将所有观察到慢滑移的地方的科学家聚集在一起来促进讨论和互动。慢滑移界现在开始超越观测研究，因为过去几年的许多新数据集和建模研究已经开始揭示产生慢滑移的物理过程。这些最近为理解流程所做的努力使得本次研讨会非常及时。会议将重点讨论以下主题：1）慢滑现象的观测，2）观察到慢地震的断层结构和物理条件，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。其形式将包括口头报告和海报。任何对慢滑移/慢地震过程有积极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结果和结构，以及建模和实验室实验。
