Geological-seismological evaluation of earthquake hazards at Franklin Falls Damsite, New Hampshire
Krinitzsky, E. L.; Dunbar, Joseph B.
Technical ReportAbstract: 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 from their sources. The site was found to be subject to a local earthquake (acceleration 0.15 g, velocity 27 cm/sec, and duration ≥ 0.5 g of 9 sec) and an earthquake originating from the Ossipee area (acceleration 0.38 g, velocity 35 cm/sec, and duration ≥ 0.05 g of 6 sec). Accelerograms and response spectra appropriate to these values were selected.
