Mataha-expedition teamNRIAGThe Mataha cooperation with Ghent University was personally encouraged by the president of the National Research institute of Astronomy and Geophysics Prof. Dr. Salah M. Mahmoud and Dr. El-Said Ahmed Al-Sayed (apllied & environmental geophysics). The Mataha geophysic research is realized by the geophysicists of the NRIAG under the general direction of Associate Prof. dr. Abbas Mohammed Abbas (member of the Egyptian committee of the protection of antiquities from environmental effects). The National Research Institute of Astronomy and Geophysics (NRIAG) is one of the oldest scientific institutions in Egypt. It was founded in Boulac (Cairo) in 1839 as an astronomical observatory. In 1865, it was transferred to Abbassia (Cairo). Finally, it was transferred to its current location (Helwan) in 1903. From that time up till now and along this time span of more than a century NRIAG has witnessed large developments and expansion phases in several disciplines such as Astronomy, Space research, Solar research, Seismology, Geomagnetism, Geoelectric, Geothermal, Gravimetry, Geodesy, Geodynamics, and recently Crustal Movements. Nowadays NRIAG plays an important application role in the national development plan of Egypt.
