Crustal Structure and Surface-wa Ve Dispersion
INTRODUCTION IN 1953, through cooperation of the Bernard Price Geophysical Institute of the University of the Witwatersrand and the University of Natal, a Columbia University-type long-period seismometer (To = 15 sec., Tg = 75 sec.) was installed in the seismological observatory of the University of Natal at Pietermaritzburg, Union of South Africa. This instrument was well situated for receivin...
متن کاملVariations in crustal structure across the transition from West to East Antarctica , Southern Victoria Land
S U M M A R Y The crustal structure beneath Ross Island and the Transantarctic Mountains (TAM) in Southern Victoria Land, Antarctica, is inferred using non-linear inversion of receiver functions, derived from teleseismic earthquake data. Intermediate-period waveforms from more than 160 teleseismic earthquakes recorded between January 1994 and January 2000 were used in the analysis. The inversio...
متن کاملCRUSTAL STRUCTURE AND SURFACE-WAVE DISPERSION* By MAURICE EwING and FRANK PRESS
A RECENT seismic refraction profile1 in 2,800 fm. (5.1 km.) at latitude 34° 00' N, longitude 66° 30' W, in the Atlantic Ocean proved that basement rocks having a velocity of 7.58 km/sec. for compressional waves were covered by 1.37 km. of sediment. We tentatively identified this velocity with either the P n velocities used in earthquake seismology for the ultra basic layer immediately beneath t...
متن کاملCrustal Structure and Surface-wave Dispersion. Part Ii Solomon Islands Earthquake of July
RAYLEIGH waves from the Solomon Islands earthquake of July 29, 1950, recorded at Honolulu, Berkeley, Tucson, and Palisades are analyzed. Both the direct waves and those propagated through the Antipodes were observed for all stations except Honolulu. Application of a correction for land travel results in a dispersion curve for the oceanic portion of the path. It is found that the observed disper...
