Title: Analysis of strong-motion data from the New Hampshire earthquake of 18 January 1982

Abstract

This report provides a permanent record and presents an analysis of the strong-motion data from the New Hampshire earthquake of 18 January 1982 which occurred at latitude 43.5 degrees N. longtitude 71.6 degrees W. Thirty-six accelerograms were recorded and digitized. The raw digitized accelerograms were processed by the US Geological Survey, Seismic Engineering Branch, to provide baseline correction and integrals are presented in tabular and graphic form. The integrated velocities and displacements are presented in graphic form. The attenuation curves of the three orthogonal components for peak acceleration, peak velocity, peak displacement, and velocity spectrum intensity on the crest, abutment, and downstream sites of the five US Army Corps of Engineers earth dams were plotted and compared. The transverse component shows the highest energy at the Franklin Falls Dam. However, its attenuation rate is faster than the vertical and longitudinal components. The transverse component of the accelerograph located on the right abutment of Franklin Falls Dam (8 km from the epicenter) recorded a maximum acceleration of 0.55 g's, which is the highest acceleration ever recorded in the eastern United States. The integrated maximum velocity is 5.59 cm/sec, which is very low in comparison with other earthquake records in the westernmore » United States or other earthquake regions. 8 references, 6 figures, 3 tables.« less
