PREFACE
This report contains P -wave data read from short-period seismograms ofO
the long-range seismic measurement arrays, known as the LRSM stations, and the
New England network. This publication documents in a tabular format the P -
wave amplitude and periods for a number of natural and man-made sources. This
effort is part of a continuing program at the U.S. Geological Survey in the
study of short-period seismic wave attenuation in the United States, under the
project of "Seismic Wave Attenuation in Conterminous United States," of the
Office of Earthquake, Volcanoes, and Engineering, Geological Division, in
Denver, Colorado. The contributing sources of this data-base have been
obtained and(or) extracted from Teledyne-Geotech, Alexandria Laboratories
(recipient of the LRSM-data films) and Weston Observatory of Boston College in
Massachusetts.

INTRODUCTION
This report presents a collection in tabular form of amplitudes and
periods of P -waves from explosive sources and earthquake recordings duringO
1961 through 1969, at sites pre-selected and identified as the long-range
seismic measurement stations, known as the LRSM stations. The tables given in
this report list the event, the epicentral distance, azimuth, period and the
amplitude of P -waves as read from microfilm records of short-period seismo-O
graphs. Table 1 lists the vertical component of ground motion. The opera
tional daily data logs made in the field, which lists all the pertinent para
meters needed to determine the seismograph system frequency response, were
used in order to correct the data listed on the subject table.
A total of 1,281 observations are listed for 115 events. The magnitude
range, reported by the U.S. Coast and Geodetic Survey for these events, is 2.0
.£_ mb 6«4. The station abbreviations used in table 1 are listed with their
coordinates in table 2.
Table 3 lists the amplitudes and periods of P -waves from explosive
sources and earthquake recordings during 1976 through 1979, on short-period
seismographs of the New England network.
DATA COLLECTION
The P -wave vertical component of ground motion is listed in table 1. OnO
this table, each event is identified and its respective teleseismic body-wave
magnitude (m^) listed. Some of the magnitudes were determined using a local
network of Wood-Anderson seismometers in the Nevada Test Site area, and their
magnitude is identified as M^. Each column in this table lists the station
abbreviation, the epicentral distance in kilometers, the azimuth in degrees,
the apparent period in seconds, and the amplitude-period ratio in millimicrons
per second.
The amplitude data were read from 0 to peak of the maximum amplitude of
the P -wave. Operational logs for the dates of each event were obtained fromO
Teledyne-Geotech, Alexandria Laboratories, in order to calibrate each of the
films containing the events being studied. After determining the short-period
seismograph frequency response, a correction was made to the scaled P -waveO
amplitudes in order to remove the instrument response of the system. The
scaled, edited, and reduced data were entered in tabular form in the computer
data-base files for the purpose of analyzing and determining the attenuation
of P -waves in conterminous United States. Figure 1 shows the location of theO
LRSM stations, identified as solid circles.
Table 3 contains the data read from short-period vertical seismograph
systems at the New England network of stations. The format is similar to the
data-base listed in table 1. The only differences are: (1) in the last
column the amplitude is listed in millimicrons, and (2) the magnitude listed
is the so called m^ of Lg or rn^CLg) used by Weston Observatory of Boston
College. There are a total of 73 events and 612 observations. Figure 2 shows
the location of the New England seismological stations.
These two data-bases are being made available so other investigators can
use them for attenuation studies or for any other regional investigation.
These data-bases have been used to derive magnitude scaling laws on a regional
basis. The data-bases analyzed have been used to determine Y for a spectral
component of 1 sec, and they have been used to determine Y using the Matrix
formulation derived in "Numerical study of attenuation of high frequency L -O
waves in the New Madrid seismic region," by J. J. Dwyer, R. B. Herrmann, and
0. W. Nuttli, U.S. Geological Survey, Open-File Report 81-112, 131 p.
