Precariously Balanced Rocks in New York, Vermont Provide Limits on Earthquake Shaking

10 September 2024–Five boulders, delivered by glacier and balancing delicately on rocky pedestals in northern New York and Vermont, can help define long-term maximum shaking intensity of earthquakes in the region. Seismologists examine the fragility of precariously balanced rocks, or PBRs, to determine the intensity of shaking would be needed … Continue Reading »
