The
Iranian plateau has long been known as one of the seismically active areas of
the world and it frequently suffers destructive and catastrophic earthquakes
that cause heavy loss of human life and widespread damage. Since prediction of
the time and magnitude of future earthquakes is at present impossible, study of
the seismic history of the country is of great importance. The relative
simplicity of the pattern of distribution of epicenters, and its relationship to
the geological features and the tectonic history of the area, is very important.
Seismology Research Center activities are organized within four departments:
Seismotectonic Department,
Seismology Department,
Engineering Seismology
Department and National
Data Center (NDC) Department.
The Seismology
Research Center main tasks are the following:
-
Field and
Instrumental studies in identification of the Seismic Sources (Faults),
Regional and Iranian crustal models, seismicity, earthquake hazard, zonation
and preparation of the earthquake data bulletins and catalogs.
-
Broadband
National Seismic Network and accelerometer installation, operation and
maintenance. Local seismicity and crustal studies by application of Mobil
Network;
-
Installation,
Operation and Maintenance of International Monitoring System (IMS) in Iran,
Operation of National Data Center (NDC), active participation in On-site
Inspection (OSI) teams and scientific support in implementation of the
Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO);
-
Design and
production of seismic stations hardware and software;
-
Providing
Ph.D. program in seismology;
-
Distribution
of earthquake location information in near real time to the media and
decision making and help organizations in Iran;
-
Providing
technical and consulting services in all aspects of the SRC activities;
-
Scientific and
technical research co-operation with Internal and International Research
Centers and Universities.
The recent
contributions and accomplishments in Seismology Achievement activities are:
Seismotectonic:
-
Development of
major active faults map of Iran (scale 1:1,000,000) and of Tehran
(scale 1:100,000) .
-
Paleoseismological study of Tabriz and Mosha active faults for more accurate
hazard assessment of cities of Tabriz and Tehran.
-
Investigation
of active tectonic of Alborz, Zagros and the transitional zone between
Zagros and Makran.
-
Detail study
of the site of petrochemical city (Asaluyeh) in south of Iran.
Seismology:
-
Installation
and maintenance of Broadband National Seismic Network.
-
Seismicity
catalog of Iran (1900-2000).
-
Global and
local GPS measurement in Iran for measuring the continental deformations.
-
Long passive
seismic monitoring across Zagros Belt from Busheher to Yazd, for crustal and
upper mantle structural definitions and investigation of subduction zone.
Seismic Hazard Analysis:
-
Processing and
detail analysis of the strong motion data recorded in Iran (1975-2000).
-
Development of
PGA and spectral value attenuation relationship for Iran.
-
Development of
detail seismic hazard zoning map of Tehran.
