In the framework of its national and regional efforts
aimed at assessing and mitigating natural disaster
risks, Libya is engaged with UNESCO in a multi·
dimensional project on earthquake monitoring and
research studies.
On 21 January 2001 UNESCO signed an agreement
with the Scientific Research Board of Libya to cany
out mutually agreed activities between UNESCO and
The Libyan Centre for Remote Sensing and Space
Sciences (LCRSSS) related to the "Establishment of
the Libyan Digital Seismological Network" (LDSN).
LDSN is a LmYAN-UNESCO project on funds • in
trust basis. The main objectives of the project are to
establish a National Digital Seismological Network
as well as a Strong Motion Network to build capacity
in earthquake monitoring and research. in order to
conduct studies of earthquake related phenomena
towards risk assessment and reduction.

Among the achievement of the project, intensive
training programmes, courses, and workshops were
designed and implemented, in service and abroad, to
prepare the technical and scientific staff for the
project. More programmes are scheduled to upgrade
skills in earthquake data analysis, research and
evaluating earthquake risk.
Extensive training programmes and workshops have
contributed to the preparation of 18 National
technicians and scientific staff for the operation and
maintenance ofthe digital network.
Collaborative projects with specialized International
scientific centers and academic institutions have
contributed to the preparation and reinforced
technical and scientific capabilities of a number of
national specialists in earthquake data analysis and
evaluating earthquake risk
The network is designed 10 monitor local, regional
and teleseisms activities as well as to provide high
quality data for research projects in regional and
global seismology.
An up.to-date 15 station digital national network,
utilizing state of the an VSAT communication
technology, and a Central Processing Centre are
successfully installed and are in full of operation
since November 2005. The network is designed to
acquire data from twelve broad band (BB) and three
very broad band (VBB) seismometers. The
continuous data is forwarded in near real·time to a
central data acquisition and processing facility, via
VSAT communication system, where it is
automatically processed. All stations are solar
powered and are equipped with a 24-bit digitizer and
VSAT communication system. Each site acquires
continuous data and relays this data directly to the
central processing facility via satellite.The
processing centre utilizes NAQS Server software for
data acquisition and network monitoring. All data
received at the central hub is forwarded to two-server
acquisition system via a single LAN connection.
Each server records the continuous data set to disk
based ring buffer and distributes the data in near realtime for automatic processing ofseismic events. The
Earthworm software provides the processing. The
software allows retrieving event data, locating
events and storing events to an Oracle database
system.

FUTURE PLANS,
In progress, as another phase of this ongoing
project, is the acquisition and installation of 30
Strong Motion(SM) Network stations, targeted at the
endof2006.
