This is the second part of the article “Spontaneously abandoned settlements in Serbia”, the first part of which was published in No. 60-2 of this Journal. Geomorphological indicators pointing at unsustainability of the studied settlements are singled out. The indicators are classified as morphometric (quantitative) and morphologic (qualitative). Geomorphometry has been used for determination of quantitative indicators. The coefficient of settlement isolation (Ki) is defined, which is a product of road coefficient (Kr) and real relative height (RRH). Morphological indicators refer to the position of a settlement on a certain geomorphological unit (ridge, valley, valley side), as well as to the geomorphological homogeneity of space, determined by geomorphological mapping. The defined indicators of unsustainability are presented in detail as a case study of the abandoned village Smilov Laz, in the municipality of Novi Pazar.
