Abstract
This work describes the data used to characterize boulders and their pedestals in the northeastern U.S. (Maine, New Hampshire, Massachusetts), which are used to calculate maximum plausible earthquake magnitudes in the surrounding region as well as scaling factors for the 2023 time-independent National Seismic Hazard Model site-specific hazard curves (Petersen et al., 2024). The work represents the current best-practice for validating hazard curves using precariously balanced rocks (e.g., Rood et al., 2020; McPhillips and Pratt, 2024).
These data support the article: Stirling, M. W., & Pratt, T. L. (2026). Use of Precariously Balanced Rocks to Constrain Postglacial Earthquake Magnitudes in New England, United States. Bulletin of the Seismological Society of America. https://doi.org/10.1785/0120250163.
