7. Natural and Technological Hazards & Ecology Strong Motion Laboratory
In order to provide permanent maintenance of the installed network and processing of the obtained strong motion records, the IZIIS Strong Motion Laboratory was established
The instruments are located in all the regions of Macedonia characterized by pronounced seismic activity and are installed on various types of structures – dams, bridges, tall buildings, industrial plants, administrative and educational buildings providing continuous monitoring of the seismic activity
In almost 40 years of operation, SMN recorded earthquakes with magnitudes 3<M<7.2 resulting in a database with more than 1200 strong motion records obtained from near and distant seismic sources on different soil conditions (bedrock and soil deposit), and different types of structures

Instruments are installed in seismic active regions in Republic of Macedonia thus providing data necessary for:
Improvment of ingeneering practice, especially for aseismic design of new and reconstruction of existing buildings;
Improvement of Tecnical Regulation and Biuilding Codes for design and construction in seismic active regions
Seismic hazard assessment, physical and urban planning;
Design and construction of essential structures (schools, hospitals)

UKIM-IZIIS in colaboration with CMC (Crisis Management Centre) started an iniative to implement the Shake Map system in Republic of Macedonia
CMC provides location for the instruments (GURALP) with necessary infrastructure (electric power, internet connection) in its premises throughout Republic of Macedonia
UKIM-IZIIS chose 13 locations and installed GURALP instruments, as part of the ShakeMap System Network
Definition and realization of two centers (one in UKIM-IZIIS, one in CMC Headquaters) for data acquisition and presentation

Responsible authorities for search and rescue operations wants rapid information on areas affected;
Government and Emergency Management need to know the likely financial impacts;
Consulting Engineers need to know the effects on structures and how close to design limits the structure has endured;
Earthquake Engineers want to know the parameters of the shaking;
Seismologists want to know the details of the fault system that caused the event;
Media want to know how the Public will be affected;
Business Leaders need to know the likely affect on their multiple locations and campuses and the safety of their structures
