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.
