Geological-Seismological Evaluation of Earthquake Hazards at Franklin Falls Damsite, New Hampshire.
Abstract
Seismic zones were developed for northern New England based on geological and geophysical data and on historic seismicity. Each zone was assigned a floating maximum earthquake and earthquake motions were attenuated to the site fron their sources. The site was found to be subject to a local earthquake (acceleration 0.15 g, velocity 27 cm/sec, and duration > or = 0.5 g of 9 sec) and an earthquake originating from the Ossipee area (acceleration 0.38 g, velocity 25 cm/sec, and duration > or = 0.05 g of 6 sec). Accelerograms and response spectra appropriate to these values were selected.
