Are microseismic ground displacements a significant geomorphic agent? (2014)
Journal Article
Brain, M., Rosser, N., Norman, E., & Petley, D. (2014). Are microseismic ground displacements a significant geomorphic agent?. Geomorphology, 207, 161-173. https://doi.org/10.1016/j.geomorph.2013.11.002

This paper considers the role that microseismic ground displacements may play in fracturing rock via cyclic loading and subcritical crack growth. Using a coastal rock cliff as a case study, we firstly undertake a literature review to define the spati... Read More about Are microseismic ground displacements a significant geomorphic agent?.
