From past earthquake data it can be seen that hilly area are more prone to seismic activity; e.g. northeast region of India. In hilly
regions, traditionally material which is locally available, like brunt brick, stone masonry and dressed stone masonry, bamboo, timber
reinforced concrete, etc., are used for the construction of houses. A scarcity of plain ground in hilly area compels the construction
activity on sloping ground. Hilly buildings constructed in masonry with mud mortar/cement mortar without conforming to seismic
codal provisions have proved unsafe and, resulted in loss of life and property when subjected to earthquake ground motions.
