abstract This paper summarizes the use of regional (Δ≦ 30°) seismic data in a test ban
context for detecting, locating, identifying, and determining the yield of underground nuclear …

A simple and powerful method for simulating ground motions is to combine parametric or
functional descriptions of the ground motion's amplitude spectrum with a random phase …

At high frequencies f the spectrum of S-wave accelerations is characterized by a trend of
exponential decay, e− πkf. In our study, the spectral decay parameter k shows little variation …

Radiated energies from shallow earthquakes with magnitudes≥ 5.8 that occurred between
1986 and 1991 are used to examine global patterns of energy release and apparent stress …

Seismic attenuation and the associated quality factor (Q) have long been studied in various
sub-disciplines of seismology, ranging from observational and engineering seismology to …

Attenuation is the anelastic process which dissipates seismic energy by conversion to heat,
thus decreasing the amplitude and modifying the frequency and phase content of a …

A database of 1700 digital seismograms from 186 earthquakes of magnitude m N 2.5–5.6
that occurred in southeastern Canada and the northeastern United States from 1990 to 2003 …

Abstract<? A3B2 twb=. 28w?> Measured and calculated values of the effective quality factor

Data from the Anza array in southern California have been analyzed to study attenuation.
The data set includes records from 68 earthquakes, each of which recorded at an average of …

Recent measurements of peak P-wave amplitudes on World Wide Standardized
