Geophysics and astronomy

This area comprises primarily the following three activities: seismology, astronomy and solar radiation measurements:

Seismology consists of measuring and monitoring the seismic activity in Tunisia in order to:

  • Prevent seismic risks and alert authorities if necessary.
  • Develop maps which trace seismic fault lines and their importance.
  • Develop and update the earthquake catalogue in Tunisia.
  • Elaborate geophysical studies.
  • Contribute to the development of earthquake engineering.
  • Prepare the seismotectonic map.
  • Study the microzonation of Greater Tunis and other regions of the country.

Astronomy allows for the execution of the following tasks:

  • Developing computation data for the observation of the lunar crescent.
  • Observing the lunar crescent nationwide.
  • Establishing lunar and solar eclipse dates.
  • Developing ephemerides.

The measurement of solar radiation consists in quantifying the different types of solar radiation in Tunisia.

Core resources of this sector:

  • A national seismology centre.
  • A regional centre of solar radiation.
  • A national seismological network.
  • A national network of accelerographs.
  • A national network of stations of solar radiation measurement.
  • A seismological data bank.
  • A radiation data bank.
