Conference on Experimental Studies of Subduction Zone Processes

俯冲带是地球上的重要界面，构造板块的汇聚会引发地震、火山、海啸和其他自然灾害。使用多种方法研究俯冲带，包括地震、大地测量和卫星观测、数值模拟和实验室实验。 在这次会议上，我们聚集了一群科学家，他们使用实验室方法重现地球内部的压力、温度、应力和化学环境，以研究控制俯冲带行为的过程。本次会议与 4 维俯冲带 (SZ4D) 计划相关，这是一项将观测、建模、实验和理论联系起来的多学科努力，旨在更好地了解俯冲带随时间和空间变化的演化。本次会议的目的是讨论研究俯冲过程的实验小组的基础设施需求。实验科学通过对材料特性（粘度、摩擦力、动态破裂、孔隙弹性、电导率、相平衡、熔化、地温气压测量、渗透性、反应动力学和扩散）的研究，直接为地震时间和位置、岩浆输送和火山喷发等各种俯冲研究提供信息。会议的参与者将来自实验岩石力学、实验岩石学/火山学和矿物物理学界。讨论的主题包括社区组织和协调、数据和方法标准化以及与俯冲带材料实验研究相关的技术问题。 参与者将讨论持续挑战的解决方案，确定利益相关者，并寻找领导者来协调未来的举措。

Subduction zones are critical interfaces in Earth where the convergence of tectonic plates gives rise to earthquakes, volcanoes, tsunami, and other natural hazards. Subduction zones are studied using a variety of methods, including seismic, geodetic, and satellite observation, numerical modeling, and laboratory experimentation. For this conference we are bringing together a community of scientists who use laboratory approaches to reproduce the pressures, temperatures, stresses, and chemical environments inside Earth to investigate the processes that control the behavior of subduction zones. This conference is connected to the Subduction Zones in 4 Dimensions (SZ4D) initiative, a multi-disciplinary effort linking observation, modeling, experiments, and theory, to better understand the time and spatially-dependent evolution of subduction zones.The objective of this conference is to discuss infrastructural needs of the experimental groups who study subduction processes. Experimental science directly informs diverse subduction research into earthquake timing and location, magma transport, and volcanic eruptions, through the study of material properties: viscosity, friction, dynamic rupture, poroelasticity, electrical conductivity, phase equilibria, melting, geothermobarometry, permeability, reaction kinetics, and diffusion. Participants for the conference will be drawn from the experimental rock mechanics, experimental petrology/volcanology, and mineral physics communities. Topics to be discussed include community organization and coordination, data and methodological standardization, and technical issues related to experimental studies on subduction zone materials. Participants will discuss solutions to persistent challenges, identify stakeholders, and seek leaders to coordinate future initiatives.
