PRF2022 is a 5-day, NSF-sponsored, GSA Penrose Conference dedicated to bringing together - in person - scientists from Rock Physics, Surface Processes, Soil Science, Stone Heritage, Critical Zone Sciences, Planetary Sciences and Geoengineering discliplines in order to open new doors to a myriad of concepts, applications and validations of all geologic work related to rock fracture.

Specifically, we are leading PRF2022 under the assertion that all natural Earth and planetary surface systems - as well as multifarious constituents of the built environment - are  intimately tied to the progressive - subcritical - growth of fractures in rock.  We are excited to discuss and debate this idea and its ramifications to a wide range of research topics. 

To further foster a sense of belonging at the conference, we will implement a mentoring scheme in advance of the conference.


The conference will also host an artist-in-residence - Melissa Riker dancer and choreographer.

Field, laboratory and modeling approaches are all encouraged.

We welcome a full range of

abstract topics -

including but not limited to:


  • Climate/Environmental dependence of fracture

  • Fracturing Processes: theory and observations

  • Landforms, erosion, and/or landscape evolution tied to rock fracture, including:  Rivers, ArchesErosion RatesLandslides/Rockfalls, Planetary Processes, Hillslopes

  • Geotechnical issues related to rock fracture

  • Crack-tip chemo-physical processes of subcritical fracture.

  • Building stone preservation related to rock fracture and vice versa

  • Fracture and stresses related to Topography/Tectonics/Gravity

  • Fracture and Stresses related to climate, freezing, thermal conditions,  biological processes, salts, chemical Processes

  • Natural Hazards related to rock fracture
