Some Recent Work on Earth Models, with Special Reference to Core Structure

Publikováno v: Geophysical Journal of the Royal Astronomical Society. 35:31-38

Summary The earlier part of the paper gives background, relating to a sequence of Earth models A", HB1, B2, HB2 and HBs, from which we have inferred that various past interpretations of certain seismic PKP precursor readings in terms of regular ray t

Comment on 'Evaluation of Models for Earthquake Source Spectra in Eastern North America' by Gail M. Atkinson and David M. Boore

Autor: R. A. W. Haddon

Publikováno v: Bulletin of the Seismological Society of America. 90:1332-1338

In their article, Atkinson and Boore (1998) (AB) attempt to evaluate a number of proposed source models for eastern North America (ENA) by comparing “predicted” ground motions for the source models against certain ground-motion data (as listed in

Use of empirical Green's functions, spectral ratios, and kinematic source models for simulating strong ground motion

Autor: R. A. W. Haddon

Publikováno v: Bulletin of the Seismological Society of America. 86:597-615

Ground motions for large and moderately large earthquakes at short and moderate distances are particularly important for seismic hazard estimation in eastern North America (ENA). Very few direct observations of such ground motions have been obtained,

Modeling of source rupture characteristics for the Saguenay earthquake of November 1988

Autor: R. A. W. Haddon

Publikováno v: Bulletin of the Seismological Society of America. 85:525-551

The magnitude mb = 6.0 Saguenay earthquake of 25 November 1988 in Quebec, Canada, was one of the largest to have occurred in eastern North America during the past half-century. Recorded high-frequency ground motions exceeded anticipated values for an

Waveform modeling of strong-motion data for the Saguenay earthquake of 25 November 1988

Autor: R. A. W. Haddon

Publikováno v: Bulletin of the Seismological Society of America. 82:720-754

The magnitude 6.0 Saguenay earthquake of 25 November 1988, in Quebec, Canada, was one of the largest recorded in eastern North America (ENA) during the past 50 years, and it has provided important high-quality data for estimation of earthquake hazard

Azimuthal anomalies of short-periodP-wave arrivals from Nahanni aftershocks, Northwest Territories, Canada, and effects of surface topography

Autor: R. A. W. Haddon, Goetz G. R. Buchbinder

Publikováno v: Bulletin of the Seismological Society of America. 80:1272-1283

Following two large earthquakes in the Northwest Territories of Canada in 1985 and one in 1988, four field surveys were undertaken to study the extensive aftershock activity. Some of the seismographs employed recorded three-component digital data, wh

Diffraction of a plane pulse by thin arbitrarily shaped obstacles

Autor: P. W. Buchen, R. A. W. Haddon

Publikováno v: The Journal of the Acoustical Society of America. 68:309-313

Kirchhoff’s time‐dependent solution of the wave equation is transformed into a convolution in the time domain, by means of a simple but effective parametrization of a plane‐wave front. It is shown how this representation can be applied to the d
