Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake-resistant construction. The predominant vulnerable building types are informal (metal, timber, GI etc.) and unreinforced brick masonry construction.
Recent earthquakes in this area have caused secondary hazards such as landslides that might have contributed to losses.
