INTRODUCTION During the quarter December 1978 through February 1979, eight hundred and twelve seismic events were detected by routine analysis of data recorded by the Indian Point Seismic Monitoring Network (IPSMN).
This represents a 29.5 per cent decrease in the number of events from that of the preceding quarter.
The decrease is due to the decline in blasting operations at the quarries (Tables IIA through IIG) and a decline in construction activity (Tables IIIA and IIIB) during the winter months.
No naturally occurring seismic events orig-inated within the IPSMN perimeter during this quarter.
Within a 100 km radius of the network, eight naturally occurring seismic events were recorded and their epicenters determined.
An additional seven events were reported by the Lamont-Doherty Geological Observatory (LDGO).
Examination of our records for the seven events reported by LDGO, revealed emergent traces for five of the events; two events were indist-inguishable above background interference.
Because the events were beyond the detectable limits of the IPSMN, focal mechanism solutions cannot be determined.
Epicenter locations are based upon LDGO data.
Other distant events, both regional and teleseismic, were recorded by the IPSMN and are presented in Tables IB and IC, respectively.
These events are too distant to be located with seismic data recorded by the IPSMN.
For these events, epicenter locations were obtained from the National Earthquake Information Service (NEIS).

Page 2 The IPSMN also recorded four atmospheric disturbances (air blasts) presented in Table ID, during the quarter.
Two air blasts, heard on a regional basis, were attributed to the Concord SSr.
The detonation of two 100 lb charges at West Point were responsible for the remaining disturbances.
DATA ANALYSIS There were no changes in basic analysis procedure during the quarter.
4 The computer program used for epicentral determinations (a modified version of HYPOELLIPSE) utilized seismic data recorded at stations operated by both the IPSMN and LDGO.
Magnitudes for all events were calculated by LDGO.
On 17 January 1979 at 7:56 am local time (12:56 UTC),
an earthquake occurred near Sandy Hook, New Jersey.
The epicenter was located approximately 85 km to the south of the IPSMN.
A magnitude of 2.2 was determined (using the Nuttli magnitude formula M )-
n On 30 January 1979 at 11:31 am local time (16:31 UTC) an earthquake occurred at Cheesequake, New Jersey.
The event was located approximately 96 km south of the IPSMN.
A magni-tude of 3.8 Mn was determined.
The tremor shook several buildings in the Cheesequake area and reportedly caused the development of a small diagonal crack in a wall at the Cheesequake Elementary School, a two story brick building.
The tremor also rattled windows in the Bensonhurst section of Brooklyn, New York, approx-imately 31 km to the northe,ast of the epicenter.
No foreshocks or aftershocks were recorded.
2309 157
Page 3 On 1 February 1979 between 9:26 pm and 10:17 pm local time (2 February 1979 between 02:26 and 03:17 UTC), a sequence of six events occurred near Chester, New Jersey, approximately 77 km to the southwest of the IPSMN.
The IPSMN recorded the two largest events, one shock (magnitude M 2.3) at 03:15 (UTC),
n and the second shock (magnitude Mn 2.1) at 03:17 (UTC).
LD30 reported additional tremors at 02:26, 02:34, 03:12 and 03:14 (UTC).
Magnitudes for these events were less than Mn 2.0 and only emergent traces were recorded by the more sensitive stations of the IPSMN.
On 11 February 1979 two seismic events were recorded at 2:21 and 2:22 am local time (07:21 and 07:22 UTC) in the vicinity of Croton Reservoir.
The tremors were located approximately 18 km to the east of the Indian Point Power Station.
Magnitudes measured Mn 1.96 and Mn 2.0 respectively.
On 23 February 1979 between 5:21 am and 5:28 pm local time (10:21 and 22:28 UTC), a foreshock, main shock, and three aftershocks occurred near Chester, New Jersey, approximately 80 km to the southwest of the IPS'4N.
The foreshock (magnitude M
2.4) occurred at 10:21 (UTC) and was followed by the main n
shock (magnitude Mn 3.0) at 10:24 (UTC).
The main shock rattled windows but caused no damage.
LDGO reported three aftershocks at 17:19, 22:05 and 22:28 (UTC).
Emergent traces of the 17:19 (UTC) aftershock were recorded by the more sensitive stations of the IPSMN.
The latter two aftershocks were not visible above background interference.
Shortly after the end of the quarter on 9 March 1979 at 11:49 pm local time (10 March 1979 at 04:49 UTC) an earthquake approximately 78 km southwest of the IPSMN near Bernardsville, New Jersey occurred.
Members of the Donald White family residing 2309 158
Page 4 at 85-4 Mountain Top Road, Bernardsville, near the epicenter of the earthquake, reported the development of a 100 foot long crack in a section of their unpaved driveway, they believed was due to the earthquake.
A team of geologists investigated and observed the ground crack and surrounding area in detail, and interviewed members of the White family on 12 March 1979.
No clear evidence was found suggesting tectonic origin of the observed ground crack; further study is being implemented.
The findings of the field investigation will be presented in greater detail in the next quarterly report.
Preliminary results of data analysis for the event are presented here:

Occasional recording difficulties were encountered which resulted from telephone line failure and, in one instance, a temporary electrical power outage.
The central recording facilities in the Woodward-Clyde Consultants Clifton Office was offline for the following periods:
