Dear Mr. Schwencer:
Forwarded herewith for your information is a copy of the Fourteenth Quarterly Report for the Seismic Monitoring Program for Indian Point covering the months of September 1978 through November 1978.
~
After this report had been prepared a seismic event of Nuttli magnitude 3.8 occured near Perth Amboy, New Jersey (40 N23.02',
740W17.60') at 11:31 E.S.T.
on January 30, 1979.
This event will be discussed in more detail in the next quarterly report.
Typographical errors in the preceding quarterly report resulted in the substitution of 1978 for 1977 on page one, paragraph two, line five; the substitution of June for July on page twa, paragraph two, line one and the omission of August from Table IIIE.
Revised pages for that report are attached.
Very truly yours,

I'NTRODUCTION During the quarter June through August 1978, nine hundred and eighty-seven seismic events were detected by routine analysis of data recorded by the Indian Point Seismic Monitoring Network (IPSMN).
This relatively large number of events is likely the result of increased quarry and road construction blasting activity during the summer months.
Three events have been identified as naturally occurring seismic events within or near the perimeter of the IPSMN.
Two of these events are main shocks; the third event is an aftershock.
One event occurred at the general location of the Annsville event of September 1977 which is within the network.
The second event and an aftershock occurred near Oakland, New Jersey approximately 20 kn outside the perimeter of the network.
Location of events was based on data obtained from seismic stations of IPSMN, Lamont-Doherty Geological Obsetvatory (LDGO) and University of Connecticut (UConn).
DATA ANALYSIS There were no changes in routine analysis procedures during this quarter.
The present computer program (a modified version of HYPOELLIPSE) to locate all three events using both IPSMN data, and data was useu from other stations.
For final epicentral locations, data from IPSMN stations, LDGO stations and UConn staticas were utilized.
On 30 June 1978 at 04:13 EDT (20: 13 UTC) a magnitude 2.9
~ event ' occurred near Oakland, New Jersey along the perimeter of the IPSMN.
This event was followed by an aftershock at 06:39 EDT (22:39 UTC) of magnitude 2.2.
Location coordinates of the two epicenters are presented in Table IA.
Both events were well recorded by all IPSMN stations and some LDGO stations.
Some LDGO stations and all t' Conn statiens recorded tho events less distinctly. -_
REV. 1 2/79 Felt report data associated with the mainshock included an area within about ten miles of the epicenter.
People reported both shaking and sounds.
The aftershock was also accompanied by felt reports.
Preliminary determination of the Modified Mercalli Intensity'of the mainshock is that of intensity MM IV.
This determination was based on data collected by LDGO.
On 23 July 1978 at 07:02 EDT (23:02 UTC) a magnitude 2.1 event occurred near Peekskill, New York within the network.
Location coordinates of this evant are presented in Table IA.
The epicentral location of this event is near the location of the Annsville, New York event of 2 September 1977.
No felt reports of this event were obtained.
Therefore, no Modified Mercalli Intensity could be determined.
Epicentral location accuracy for t.ase events is generally good (better than 2 km within the horizontal plane).
Due to gaps in station distribution with respect to epicentral locations, however, and poor first motion data recorded by most stations of IPSMN, LDGO, and UConn, we have been unable to compute reliable foca.1 mechanism solutions for any of these three events.
Other distant events, both regional and teleseisms, were recorded by the IPSMN.
These events are summarized in Table IB and IC.
These events are too distant to be located by the network; locational and other data for these events were obtained primarily from LDGO.
A total of eight events occurred in a region within six degrees of the IPSMN; see Table IB.
Four events occurred in the vicinity of Bermuda.
These include events of 4 June 1978 at 09:08 UTC, 11 August 1978 at 08:09 UTC, 17 August 1978 at 09:49 UTC, and 30 August 1978 at 07:30 UTC.
A magnitude 3.0 event occurred near Lancaster, Pennsylvania or.15 July 1978 at 06:40 UTC.
Two events of undertermined magnitude occurred off the coast.

e INTRODUCTION During the quac+ar September through November 1973, one thousand one hundred and fif ty one seismic events were detected by routine analysis of data recorded by the Indi a Point Seismic Monitoring Network (IP3MN). This figure represents a 16.6 per cent increase in seismic disturbances compared to the preceding quarter. The increased number of seismic events is attributed to a 15 per cent rise in blasting operations at the quarries listed in Tab!cs IIA through IIG.
Increased constructional activity in the area encompassed by and adjacent to the IPSMN resulted in a 20 per cent rise in man-made seismic events which are presented in Tables IIIA and IIIB.
No naturally occurring seismic events originated within the IPSMN perimeter ducing this quarter. One such event, of minor significance, occurred outside the
"~
perimeter of the network and was located approximately 25 km to the southeast of the network in Yonkers, New York.
DATA ANALYSIS There were no cnanges in analysis procedure during this quarter.
The computer program used for epicentral determinations (a modified version of HYPOELLIPSE) utilized seismic data recorded at stations operated by both the IPSMN and the Lamont-Doherty Geological Observatory (LDGO).
On 19 September 1978 at 12:11 a.m. EDT (04:11 UTC) a minor shock, recorded by 12 of the 13 IPSMN stations and 4 I.DGO stations, originated in Yonkers, New York.
LDG0 calculatnd a 1.8 magnitude for the event.
No foreshocks or af tershocks were instrumentality recorded. No felt reports of this event were obtained and no Modified Mercalli Intensity computed.
Epicenter coordinates of the event are presented in Table IA and the epicenter is located in Figure 1.
emme
B Other distant events, both regional and teleseismic, were recorded by the IPSMN and are presented in Tables IB and IC respectively. In most instances thesc events are tofdistant to be located with seismic data recorded by the IPSMN. For those events epicenter locations were obtained from LDGO and the National Earthquake Information Service.
STATUS OF THE NETWORK Network statiens operated satisfactorily during this quarter; coordinates of network stations are listed in Table IV and station locations are shown in Figur< I.
Occasional difficulties were enct
.ared which resulted from dataphone failure; the central recording equipment in the Woodward-Clyde ConsultEnts Clif ton office was offline for the following periods:
Date Time UTC 21 October 1978 16:24 to 17:22 27 October 1978 08:19 to 12:41 28 - 29 October 1978 21:00 to 17:50 05 November 1978 04:19 to 14:00 15 - 16 November 1978 22:46 to 20:06 A review of LDG0 data for these time periods indicates that no events of significance to the IPSMN occurred.
