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.

俯冲带是地球上的关键界面，在那里，构造板块的会聚会引起地震，火山，海啸和其他自然灾害。俯冲带的研究使用了多种方法，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，我们聚集了一批科学家，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。本次会议与四维俯冲带（SZ 4D）倡议有关，该倡议是一项将观测、建模、实验和理论相结合的多学科努力，旨在更好地了解俯冲带的时间和空间依赖性演化。本次会议的目的是讨论研究俯冲过程的实验组的基础设施需求。实验科学通过研究物质的性质（粘性、摩擦、动态破裂、孔隙弹性、导电性、相平衡、熔化、地质温压、渗透性、反应动力学和扩散），直接将各种俯冲研究告知地震的时间和位置、岩浆运输和火山爆发。会议的与会者将来自实验岩石力学，实验岩石学/火山学和矿物物理学社区。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物质实验研究有关的技术问题。 与会者将讨论持续挑战的解决方案，确定利益相关者，并寻求领导者协调未来的举措。
