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, 2010. 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 14
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 and 8 analog strong-motion stations. 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 and 2, respectively. The 14 stations consist of Guralp CMG-40T threecomponent sensors. Ground motions recorded by these sensors are digitized at 40 sps with 16-bit
resolution. Additional gain-ranging provides 126 dB dynamic range. These stations are operated
in continuous mode with all waveform data transmitted via the internet to Weston Observatory
for analysis and event archiving.
Seismicity
There were 14 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 January, 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://quake.bc.edu:8000/quakes_recent.htm. Waveform
data are saved in SAC, and SEED formats and are available through the IRIS DMC at:
http://www.iris.edu/dms/dmc/. Earthquake catalogs can be found at:
www.bc.edu/research/westonobservatory/northeast/eqcatalogs/ and http://quake.bc.edu:8000/cgibin/NESN/recent_events.pl. Currently available on the Weston Observatory web page is the full
catalog of northeastern U.S. earthquake activity. For more information consult our web site,
