Local geological effects on short-period Rayleigh waves around New York City

LAMONT-DOHERTY GEOLOGICAL OBSERVATORY COLUMBIA UNIVERSITY, PALISADES, NEW YORK 10964

Abstract

Explosion-generated Rayleigh waves of periods 0.2 to 1.5 sec show strong lateral refraction caused by contrasting shallow rock layers at the boundary between high-velocity crystalline metamorphic rocks of the Manhattan prong and low-velocity Triassic rocks of the Newark basin. The earliest-arriving Rayleigh waves between sources and a receiver in the Newark basin are refracted through the metamorphic province. For the slower but more direct paths within the Newark basin, phase velocity is determined using two source locations and one receiver. The observed Rayleigh group and phase velocities are consistent with layered velocity models derived from geological and geophysical information.
