INTRODUCTION

In this report we examine coda characteristics for

earthquakes from 15 seismic regions as recorded at 17

World Wide Standard Seismograph Station (WWSSS). Whenever

possible, events with body wave magritude ra. > 6.0 were

examined, since the coda for large events stay above

the ambient noise level for relatively longer time periods.

In this report, we present the average coda

determinations and their standard deviations, and some

general observations on coda characteristics. These

data can be used, for example, to determine how often

the signals from one event are masked in the coda of

another event.

DATA

Using the list of seismic events compiled by the

National Oceanic and Atmospheric Administration (NOAA),

earthquakes with m. > 6.0 were selected for each region

shown in Figure 1 (Table I), Film chips of seismograms

recorded for these events by 17 WWSSS stations (Figure 2,

Table II) were then ordered from NOAA for study. For

reasons related to seismogram quality and station outage,

the original ist of events was supplemented with events

of m. < 6. Summary lists of the events studied, together

with the stations used with each event, are given in

Tables III through XVII. Table XVIII summarizes the data

analyzed by station, region, and phase (P or PKP).

ANALYSIS TECHNIQUES

The method used to determine coda decay character-

istics is shown in Figure 3. Amplitude measurements,

scaled relative to the largest excursion in the F or

PKP coda, are made in a specified set of successive time

windows. Measurements are made until the coda decays

into the pre-existing ambient noise level, or until a

period of 15 minutes has elapsed from the time of coda

onset. In a few cases, measurements terminated with the

arrival of a second event.

The principal coda maxima are next plotted on log-

linear paper, and the coda envelope obtained by connecting

successive determinations. For example, the coda measure-

ments of Figure 3 yield the coda envelope shown in

Figure 4a, If the coda measurements for a set of events

from a given region are plotted for a station, a graph

similar to that in Figure 4b may be obtained. The coda

characteristic for events from a given region as

recorded at a particular station may then be defined

in several ways. One might construct an envelope which

allows 51 (or one) of the coda determinations to fall

below the curve specified. Alternatively, as is done in

this report, the average coda can be determined and a

statistic associated with the spread in data.

RESULTS

Coda decay characteristics for events in the 15

regions studied are given in Figures 6 through 272 (see

List of Figures for a breakdown of figure numbers by

region and station). The individual coda are shown by

Hotted lines, while he solid line shows the average

c>da decay curve. The table accompanying each graph

lists the average coda values and their corresponding

standard deviations (in units of m. ) as a function of

elapsed time. In determining the average coda decay

curve, coda observations for a given event were termi-

nated at the minimum coda value observed for that event.

Whether the P or PKP coda is given for a station

depends on the station's distance from the events

analyzed. In some cases a station will see P for events

in one portion of a region, while PKP will arrive first

from events in another portion. Where this occurs, two

graphs of coda characteristics are given. One observa-

tion to be drawn from these data is that coda charac-

teristics are not strongly influenced by epicentral

region, they are controlled primarily by the arrival

times of significant secondary phases. To illustrate

this, we cite below several types of coda characteristics,

grouped by epicentral distance:

I 20° - 45°

II 45° - 80°

III 80° - 105°

In the first distance range, 20° to 45°, reference

to the travel-time curves for P phases (Figure 5) shows

that the secondary phase PP should arrive up to 2 minutes

after the P phase. Further, one might expect a third

arrival, PcP 4 to 2 minutes into the P coda. Between 35°

and 45°, ScP is observed 5 to 6 minutes after the arrival

of P. Though not shown in Figure 5, between 6 and 20

minutes into the P coda, surface-wave arrivals should be

observed. This characterization is seen, for example, in

the coda determined for California-Western United States

events recorded at CMC (Figure 48, 25-42°), for Solomon

Islands->iew Hebrides events recorded at ADE (Figure 149,

30-34°; and for Iran-Turkey events recorded at NDI

(Figure 235, 19-35°). These data, together with other

well-determined coda characteristics for events recorded

at epicentral distances between 20° to 45° (Table XIX)

yield the results shown in Figure 274. The a/erage coda

decay curve has a representative standard deviation of about ♦ .25 mb units.

One caution should be noted in using the coda

determined for the range 20° to 45°. While high coda

levels are observed in the P coda due to the arrival of

surface waves, these arrivals have periods on the order

of 1 to 3 seconds, and sometime« greater. As such,

despite the high amplitude of the surface wave arrival,

the arrival from an explosion, due to its shorter period,

may be distinguishable in the surface-wave background.

Use of coda where large-amplitude suface-wave arrivals

are present therefore, will lead one to overestimate tha

number of masking opportunities. We suggest that in

computing masking opportunities, large-amplitude surface-

wave arrivals should be omitted, and the coda allowed to

decay at rates determined elsewhere in this report.

In the distance interval 45° to 80°, PcP is the

first secondary arrival which is both predictable and

significant. This phase arrives between 2 and 0 minutes

after the P arrival in the distance range considered,

and precedes the arrival of the somewhat less significant

PP phase by 0 to 3 minutes. Representative coda fo» ipi-

central distances of froja 45° to 80° include the coda

for Kamchatka-Kurile Island events recorded it BOZ

(S4-65-) for Japan events recorded at NDI (51-61*), and

for Philippine Island events recorded at SHI (60-78°).

These coda sets, together with those listed in Table XX

were used to produce the 4So-to-80', coda representation

shown in Figure 27S. The average curve determined from

the composite data set has a standard deviation of

about 1 .25 nu units. For elapsed times between 4 and

10 minutes, the coda decay constant X is .0017 per

second (e~ ; t in seconds).

With respect to the distance interval 80° to 105°,

we fine», first, that between 80° and 90°, P and PcP

arrive almost simultaneously; the largest coda amplitude,

the efore, is generally found in the first 30 seconds of

the short-period record. An example of coda in this range

is the data for Kamchatka-Kurile Island events recorded

at WES (Figure 112). Beyond 90°, P becomes weaker, and

both P and PP, the latter delayed 3 to 4 minutes relative

to P, control the coda characteristics (see, for example,

the data for South American events recorded at CMC

(Figure 11)). Using the data given in Table XXI, we

obtain the average 80° to 105° coda representation shown

in Figure 276. The nominal standard deviation is ♦ .25 m. — b

units. At elapsed times between 4 and 9 minutes, the

iverage coda decay constant is .0037 per second.

Beyond 105° a great variation in cod^ characteiistics

as a function of distance is observed. For example,

between 105° and 110°, the first arrival, which may or

may not be observed due to its low amplitude, is

diffracted P. This arrival fi followed about 4,5 minutes

later by PP, whicii is the largest-amplitude phase in

the P co'ia in this distance interval. The coda decay

curve shown in Figure 6, obtained from a South American

event recorded at ADE (A-1070), exhibits these charac-

teristics.

In the distance interval 110° to 120°, it may be

possible to observe weak diffracted P signals as the

first arrival. The arrival of this phase, if it is

observed, will be followed about 4 minutes later by the

arrival or PKIKP, the largest-amplitude phase in the

short-period seismogram. Approximately 1 minute after

the arrival of PKIKP, PP will arrive, followed approxi-

mately 3 minutes later by the arrival of SKP (PKIKP-SKP~4

minutes). The coda characteristics observed at DAL for

a large (m^ • 6.S) Tadzhik event (Figure 244) display

these features.

Between 120° and 140°, the first arrival, PKIKP,

is the largest amplitude phase on the short-period

vertical record, r Uowing this arrival by approxi-

mately 3.5 minutes is the phase SKP. SKP is also of

large amplitude, and is more readily observable than PP,

which can arrive up to 2 minutes earlier than SKP in

this distance interval. Examples of these characteristics

are seen in the coda determined for Central American

events recorded at ND1 (Figure 40).

In the distance interval 140° to 150°, PKP. and

PKI'2 arrive almost simultaneously, producing a large-

amplitude first arrival. Approximately 3 minutes into

the PKP coda, PP arrives, followed shortly thereafter

(-0.5 minutes) by the arrival of SK0. Several of the

PKP coda observed for Central American events recorded

at CHG exhibit these characteristics (Figure 29). Though

not apparent in Figure 29 (due to the manner in which

the coda are quantified), PP is dominant over SKP in

this distance interval.

Beyond 150°, the first arrival is PKP,, followed

up to 2 minutes later by tne arrival of PKP2. Of the

two, PKP, is stronger. PKP2, in turn, is followed

approximately 3.5 minutes later by the arrival ot PP.

The coda for South American events recorded at CHG

(Figure 10) exhibit these characteristics.

A second finding of this study if that coda

determined from large events (6,0?m.<J7.0) appear

applicable to smaller events as well. To sec this, we

show in Figures 277 through 279 some earlier coda

determinations for Kamchatka-Kurile Islands events

recorded at NP-NT, RK-ON, and WMO. These coda were

determined for events in the magnitude range 5.0^m.^5.8.

Compare the NP-NT coda with the coda obtained at MUN

(6.Ü^mj*6.7; Figure 162) for Solomon Islands-New Hebrides

events. Both sets of determinations have their peak values

in the first 30 seconds of the seismogram, thereafter

falling to a relative minima (10% to i0\) at an elapsed

time of about one minute. A relative maxima (20» to 50t)

is observed for both data sets between l.S and 2.5

minutes, most probably related to the arrival of PcP.

Following this relative maxima, the coda decay to values

on the order of 5t to 201 at an elapsed time of 5 minutes,

For comparison, the average coda decay curve determined

for the MUN data is superimposed on the NP-NT data.

Given the spread in observations observed for the MUN

coda (-.3 mb units), we can not reject the hypothesis

that the average coda decay curve determined from the

MUN coda is representative of the average decay charac- teristics for the NP-NT data.

Similar observations can be made using the Kamchatka-

Kurile Islands coda decay curves determined at RK-ON

(Figure 278) and the Alaskan data obtained for KON

(5.7<mb<6.8; Figure 71) and using Kamchatka-Kurile

Islands data from WMO (Figure 279) and 1ST (5.8^7.0;

Figure 103). These comparisons suggest that the average

coda decay curves presented in this report should be

applicable over a magnitude range of at least 5.0?mb?7.0.

CONCLUSIONS

From an examination of P and PKP coda for earthquakes

from 15 seismic regions as recorded at 17 World Wide

Standard Seismograph Stations, we conclude:

1. Coda for events in a given region recorded at

a given distance are found to be very similar to the

coda for events from another region recorded at the

same distance. That is, coda characteristics are

determined primarily by the arrival times and amplitudes

of significant secondary phases.

2. Coda characteristics determined for large events

(ö.O^ra. ?7.0) appear applicable to smaller events

(S.O^m. 5!6,0) a*» well. The average coda determinations

presented in this report, therefore, are representative

of coda for events in the range S.O^m. ?7,0.

3. Using data in the range 450<A<800, the long-term

P-coda decay constant V for elapsed times greater than

4 minutes is ,0017 per second (e' ), In the range

800<A<1050, the decay constant is somewhat larger,

being on the order of .0037 per second.
