The 2022 Penrose Conference of the Geological Society of America on progressive rock failure (PRF2022) will bring together approximately 75 international scientists and engineers to facilitate a step-change in our understanding of rock fracture in both built and natural environments. To fully understand rock fracture is to understand elements of Earth that are critical for societal health and safety including: natural hazards related to rockfalls and landslides; degradation of rock-related infrastructure; rock weathering and erosion; and even the size and distribution of sedimentary particles and the internal structure – architecture - of Earth’s uppermost crust, which contribute to Earth’s soils and hold its water and natural resources. Yet, traditionally geoscientists studying natural rock fracture have largely overlooked the knowledge and implications to be derived from rock physics and engineering research, and vice versa. Therefore, a key goal of PRF2022 is to open doors to new insights that may be gained by studying progressive rock failure in the context of geotechnical engineering, surface processes, natural hazards and stone heritage problems. This goal will be achieved by maximizing both disciplinary diversity and participant diversity of the conference. To ensure longevity and accessibility of conference’s outcomes, PRF2022 will also provide a mentoring scheme for early career and student attendees and communicate the conference ideas with the public and among scientists themselves. There is a burgeoning recognition of 1) the central role that fractures play in Critical Zone processes, landscape evolution, and geotechnical problems; and 2) a ‘new’ realm of fracture mechanics that applies to both engineered and natural surface processes but has been understudied in those contexts - namely progressive rock failure (a.k.a. subcritical cracking, environmental cracking and microcracking). In particular, the role of progressive rock failure in natural rock fracture has been largely unrecognized or misunderstood across a wide array of both surface process and engineering applications, where it likely plays a dominant role. To best leverage recent, rapidly evolving cross-discipline conceptualizations of rock fracture and its relationship to erosion, hazards, preservation, climate, and chemical weathering, this Penrose Conference will be held in Western North Carolina, USA (June 2022). PRF2022 will: provide a platform to identify complementary data/observations and modelling approaches; reveal key existing and needed datasets; stimulate new multidisciplinary collaborations and scientific and commercial funding opportunities; and build a framework for future evaluation of PRF within both academic and applied Earth sciences questions.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.

2022年美国地质学会关于渐进岩石破坏的彭罗斯会议（PRF 2022）将汇集大约75名国际科学家和工程师，以促进我们对建筑和自然环境中岩石断裂的理解的逐步变化。要充分了解岩石断裂，就必须了解对社会健康和安全至关重要的地球要素，包括：与岩崩和滑坡有关的自然灾害;与岩石有关的基础设施退化;岩石风化和侵蚀;甚至是沉积颗粒的大小和分布，以及地球最上层地壳的内部结构，它们对地球的土壤、水和自然资源都有贡献。 然而，传统上研究天然岩石断裂的地球科学家在很大程度上忽视了岩石物理和工程研究的知识和意义，反之亦然。因此，PRF 2022的一个关键目标是打开大门，通过研究岩土工程，表面处理，自然灾害和石材遗产问题的背景下渐进岩石破坏可能获得新的见解。 这一目标将通过最大限度地提高会议的学科多样性和参与者多样性来实现。为了确保会议成果的持久性和可访问性，PRF 2022还将为早期职业和学生与会者提供指导计划，并与公众和科学家之间交流会议想法。有一个新兴的认识：1）断裂在临界带过程，景观演变和岩土工程问题中发挥的核心作用; 2）断裂力学的“新”领域，适用于工程和自然表面过程，但在这些背景下研究不足-即渐进岩石破坏（又名。亚临界裂纹、环境裂纹和微裂纹）。特别是，渐进式岩石破坏在天然岩石断裂中的作用在很大程度上未被认识或误解，在表面处理和工程应用中，它可能起着主导作用。为了最好地利用最近迅速发展的岩石断裂跨学科概念及其与侵蚀，灾害，保护，气候和化学风化的关系，彭罗斯会议将在美国北卡罗来纳州西部举行（2022年6月）。PRF 2022将：提供一个平台，以确定补充数据/观测和建模方法;揭示关键的现有和所需数据集;促进新的多学科合作以及科学和商业资助机会;该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识产权进行评估来支持。优点和更广泛的影响审查标准。
