George 's acceptance of the Seljuq suzerainty did not bring a real peace for Georgia . The Turks continued their seasonal movement into the Georgian territory to make use of the rich herbage of the Kura valley and the Seljuq garrisons occupied the key fortresses in Georgia 's south . These inroads and settlements had a ruinous effect on Georgia 's economic and political order . Cultivated lands were turned into pastures for the nomads and peasant farmers were compelled to seek safety in the mountains . The contemporary Georgian chronicler laments that " in those times there was neither sowing nor harvest . The land was ruined and turned into forest ; in place of men beasts and animals of the field made their dwelling there . Insufferable oppression fell on all the inhabitants of the land ; it was unparalleled and far worse than all ravages heard of or experienced . " A similar situation was found in neighboring Armenia as related in Aristakes Lastivertsi 's chronicle . To make the things worse , a severe earthquake struck the southern provinces of Georgia , devastating Tmogvi and the surrounding area on April 16 , 1088
