Introduction

The New England Seismic Network (NESN) is operated by the Weston Observatory (WES) of

Boston College. The mission of the NESN is to operate and maintain a regional seismic network

with digital recording of seismic ground motions for the following purposes: 1) to determine the

location and magnitude of earthquakes in and adjacent to New England and report felt events to

public safety agencies, 2) to define the crust and upper mantle structure of the northeastern

United States, 3) to derive the source parameters of New England earthquakes, and 4) to estimate

the seismic hazard in the area.

This report summarizes the work of the NESN for the period July - September, 2011. It includes

a brief summary of the network's equipment and operation, and a short discussion of data

management procedures. A list of participating personnel is given in Table 1. There were 32

earthquakes that occurred within or near the network during this reporting period. Phase

information for these earthquakes is included in this report.

Current Network Operation and Status

The New England Seismic Network of Weston Observatory of Boston College currently consists

of 14 broadband three-component sensors as well as 14 strong motion three-component sensors.

The coordinates of the broadband stations are given in Table 2, and maps of the weak- and

strong-motion networks are shown in Figures 1. The 14 stations consist of Nanometrics 120PA

three-component broadband sensors as well as Reftek RT-147 Accelerometers (Strong Motion

Sensors). Ground motions recorded by these sensors are digitized at 40 sps. These stations are

Page 4: A STUDY OF NEW ENGLAND SEISMICITY - Boston College · table 3 earthquake hypocenters date time lat long depth mn mc location 2011/09/30 18:19:22.36 42.90 74.21 05.01 1.4 2.3 ny, 4.0km

operated in continuous mode with all waveform data transmitted via the internet to Weston

Observatory for analysis and event archiving.

Seismicity

There were 32 earthquakes that occurred in or adjacent to the NESN during this reporting period.

A summary of the location data is given in Table 3. Figure 3 shows the locations of these events.

Figure 4 shows the locations of all events since the beginning of network operation in October,

1975.

Table 4 gives the station phase data for each event listed in Table 3. In addition to NESN data,

arrival time and magnitude data sometimes are contributed for seismic stations operated by the

Geological Survey of Canada (GSC), the Lamont-Doherty Cooperative Seismographic Network

(LD), and the US National Seismic Network. Final locations for this section were computed

using the program HYPO78. For regional events (those too far from the NESN to obtain accurate

locations and magnitudes) phase data are given for NESN stations, but the entry in Table 3 lists

the hypocenter and geographic location information adopted from the authoritative network.

Accordingly, the epicenter is plotted on the maps using the entry from Table 3.

Data Management

Recent event locations are available at

http://aki.bc.edu/cgi-bin/NESN/recent_events.pl

Waveform data are saved in SAC, and SEED formats and are available through the IRIS DMC

at: http://www.iris.edu/dms/dmc/

Northeastern U.S. earthquake catalogs can be found at:

www.bc.edu/research/westonobservatory/northeast/eqcatalogs/ and
