Analytic Hierarchy Process and Weighted Linear Combination method were used to create a landslide susceptibility map for the study area. The produced map provides valuable information concerning the stability conditions ojthe territOly and may serve as the first step in a complete hazard assessment towards the mitigation 0.( natural land slide disasters in Messinia PreJecture area. Particularly the intention is to transfer effectively inJormation regarding slope stability to non-geologists who take deci sions Jor future land use planning processes and major construction projects. Key words: Analytic Hierarchy Process, Weighted Linear Combination, Kalamata. nEp fA 'l4J11 LKon6~ r'7~ E:p)la(Jia~ elvQ./ '7 E:Kriji'7!J'7 rrr~ C7rtKlVi50v6r'1w~ ac KaroJ..laO~ocz~ E:v6~ rjir,f.l(J.ro~ roo NOjioV ME:mJ'7via~, nov 7[cpIAajifirivE:t roo~ iJ~jiOVC; Kalr.J.paw~, Afiiac; KW AdJlcrpov, {.IE: TI] rJVv(joaojil;v'1 Xp~!J'7 JE:wyparpzKwv LIHJT11jiarWv [JA'1POrpOpIWV K(J.Z [JOAVKpmlPWKWV Mc86bwv LTl7pl('1r; Anorpa.ofwv.
