P f APreface - MAEE
• 1964 - MAEE (Macedonian Association of Earthquake Engineering) as a part of the Yugoslav Association for
h k i iEarthquake Engineering• 1964 - Under the auspices of UNESCO, MAEE and IZIIS
organized the International Seminar on Earthquake organized the International Seminar on Earthquake Engineering, Skopje, Sep. 29 – Oct. 3, 1964 (nowadays referred to as the First EAEE Symposium). The most referred to as the First EAEE Symposium). The most significant achievement of the Skopje International Seminar was the foundation (October 1, 1964) of the EAEE, initially called the European Commission (of IAEE) for Earthquake Engineering
