Landslide hazard analysis in Harzand- Piraz (Oryantapeh) village, Marand-Azerbaijan- Iran (Case study)
Azerbaijan area (NW Iran) is a region of intense deformation on seismicity, situated between two thrust belts of the Caucasus to the north and the Zagros Mountain to the South. Landslides are the consequence of diverse and complex processes that probably affect every country that has topographic relief. In Azerbaijan, development of landslide hazard areas is occurring at a greater rate than In previous years. The region under survey is located in a slope mountain called; Shorbayer its slope is about 30 to 40 percent. September 2, 2008 and previous earthquakes cause a vast number of phenomena such as landslide and rock- falls along the southern slope of Harzand- Oryantapeh mountain and many of rural homes suffred of heavy damages. The direct effect of the catastrophic April 1981 and especially September 2, 2008 heavy earthquake and meteorological event was the reactivation of a large ancient rockslide, which affects the middle- lower part of Oryantapeh- Harzand Southern Slope. The Slide involves a massive dacitic and volcanic rock mass the overall surface approximately is: V = 1/3πab · h = 1/3 π · 1500 · 750 · 100 = 1178 · 106m3.
