Earthquake Strong Motion Database: Lamont-Doherty Earth Observatory, National Center for Earthquake Engineering Research (LDEO/NCEER)

The Lamont-Doherty Earth Observatory / National Center for Earthquake
Engineering Research (LDEO/NCEER) Earthquake Strong Motion Database
contains a variety of strong motion earthquake recordings from the
joint LDEO/NCEER/USGS strong motion digital accelerograph network as
well as other sources including: National Geophysical Data Center,
U.S. Geological Survey, Canadian Geological Survey, U.S. Army Corps of
Engineers and other agencies. The database is accessible via the
World Wide Web at:

http://www.ldgo.columbia.edu/nceer/nceer.html

The database is also accessible through the STRONGMO program which may
be accessed via: ftp, telnet, modem, and rlogin. An online manual
(ftp://ldeo.columbia.edu:/nceer/strongmo.txt) is available. This
manual describes the following ways to connect to the database:

Modem:
The phone number to gain access to Lamont is [phone] or
365-8191.
The parameters that must be set in order for the connection to work
are as follows:
Baud Rate: 2400
Parity: none
Data Bits: 8
Stop Bits: 1
Duplex: full

The user will be connected to a database which allows the user to
query the database on a variety of search criteria. General parameters
include: event phenomena, record parameters, site parameters and trace
parameters.

Searchable fields for each seismic event include:
year, month, day, hour/min, number, name, country, state, latitude,
longitude, depth, location of source, magnitudes, moment data,
mechinism data, and further comments.

Online documentation is available, including the following description
of the STRONGMO program and the NCEER Strong Motion Data Base:

STRONGMO..., is part of the NCEER Strong Ground Motion Facility's
effort to develop a data base in which strong ground motion data is
retrievable over a telecommunications line or a computer
network. The tool is still in its experimental stages, so be
wary. Presently the user has the capability to interogate the NCEER
Strong Motion Data Base and then retrieve selected strong motion data
(both parametric and time-series) via kermit, a communications program
developed at Columbia University. The tool also provides the user with
the ability to: contact staff at Lamont via electronic mail; find out
the latest status of the NCEER/Lamont Digital Strong-Motion Network;
and retrieve raw data retrieved from the Network.

The Data Base consists of a comprehensive collection of earthquake,
strong motion record, time-series, and recording site parameters. The
data itself comes from two different sources; 20 digitally recording
accelerographs operated by Lamont and NCEER and over 50 magnetic tapes
that were purchased from several strong motion data archiving
agencies, including: the National Geophysical Data Center in Boulder,
Colorado; Calif. Div. of Mines and Geology; and the United States
Geological Survey in Menlo Park, California.
