Despite the global urgency to mitigate the risk from geohazards, we still have limited understanding of the fundamental drivers behind earthquakes, tsunamis, volcanic eruptions, and landslides, and thus their predictability in time and space. The SZ4D (Subduction Zones in Four Dimensions) initiative is a community-driven effort that strives to address this need directly by coordinating and enabling fundamental research on the underlying physical and chemical characteristics and processes specifically in subduction zones. SZ4D seeks to answer the following questions: When and where do large damaging earthquakes happen? How do trans-crustal processes initiate eruptions at arc volcanoes? How do events within Earth’s atmosphere, hydrosphere, and solid Earth generate and transport sediment across subduction zone landscapes and seascapes? What fraction of a subduction zone’s energy budget goes into building and shaping subduction zone land- and seascapes? How can we transform the mindset of our geoscience community to embrace education, outreach, accessibility, capacity building, diversity, equity, inclusion, and social justice as critical components for the success of the SZ4D and future scientific endeavors by the geosciences community? Answering these questions will require a substantial infrastructure investment in the form of instrumental arrays accompanied by support for field, modeling and laboratory science.The expansive vision of SZ4D needs cost estimates, time phasing and project planning in order to prepare for full submission to the Foundation and any partnering agencies. This proposal lays out a plan to accomplish this development quickly. The major components of this proposed SZ4D catalyst effort are: 1) A staffed center that will organize the work and build equity and capacity in the Geosciences (BECG) following a Collective Impact model. 2) Technical project management to realistically evaluate costs and trade-offs of the instrumentation options. 3) Preparatory work for the geological, modeling and laboratory facilities which include workshops and modest engineering design work. All of these specific activities were strategically selected because they directly affect high-priority elements of the draft implementation plan and have identifiable, tractable development needs that should be addressed prior to launch of a full SZ4D program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

尽管全球迫切需要减轻地质灾害的风险，但我们对地震、海啸、火山爆发和山体滑坡背后的基本驱动因素及其在时间和空间上的可预测性的了解仍然有限。SZ4D（四维俯冲带）倡议是一项社区驱动的努力，旨在通过协调和促进对俯冲带基本物理和化学特征和过程的基础研究来直接解决这一需求。SZ4D试图回答以下问题：大破坏性地震何时何地发生？跨地壳的过程如何引发弧火山的喷发？地球大气层、水圈和固体地球内的事件如何产生沉积物并将其输送到俯冲带景观和海景？俯冲带的能量预算中有多少部分用于建造和塑造俯冲带的陆地和海洋景观？我们如何改变地球科学界的心态，将教育、推广、可及性、能力建设、多样性、公平、包容和社会正义作为SZ4D和地球科学界未来科学努力成功的关键组成部分？解决这些问题将需要大量的基础设施投资，以仪器阵列的形式，并伴随着对现场，建模和实验室科学的支持。SZ4D的广阔愿景需要成本估算，时间安排和项目规划，以便准备向基金会和任何合作机构提交完整的项目。该提案提出了一个快速完成这一发展的计划。这一拟议的SZ4D催化剂工作的主要组成部分是：1）一个配备人员的中心，该中心将按照集体影响模型组织工作并建立地球科学（BECG）的公平和能力。2)技术项目管理，以现实地评估成本和仪器选项的权衡。3)地质、建模和实验室设施的准备工作，包括研讨会和适度的工程设计工作。所有这些具体活动都是战略性选择的，因为它们直接影响到实施计划草案的高优先级要素，并且具有可识别的、易处理的发展需求，这些需求应在启动完整的SZ4D计划之前得到解决。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
