Conference on Experimental Studies of Subduction Zone Processes

俯冲带是地球上构造板块汇聚引发地震、火山、海啸和其他自然灾害的关键界面。俯冲带的研究方法多种多样，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再现地球内部的压力、温度、压力和化学环境，以研究控制俯冲带行为的过程。这次会议与四维俯冲带(SZ4D)倡议有关，该倡议是一个多学科的努力，将观测、建模、实验和理论联系在一起，以更好地了解俯冲带随时间和空间的演化。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。实验科学通过研究物质性质：粘度、摩擦力、动态破裂、孔弹性、导电性、相平衡、熔融、地热气压、渗透率、反应动力学和扩散，直接为地震时间和地点、岩浆运输和火山喷发提供不同的俯冲研究。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社区。将讨论的议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有关的技术问题。与会者将讨论应对持续挑战的解决方案，确定利益相关者，并寻找领导人来协调未来的倡议。

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.
