CBSE Book Class 10 Disaster Management Safe Construction Practices

A powerful earthquake measuring 6.6 at the Richter scale struck SOUTHEASTERN IRAN on 26th December, 2003 at 5:26:52 AM (local time) and caused enormous loss of life, and near total destruction of physical assets, killing 30,000 people and injured another 30,000. The health and education infrastructure was severely damaged and over 85% houses collapsed.

A super cyclone slammed the state of Orissa on October 29, 1999 with a wind speed of 270-300 kmph, accompanied by torrential rains ranging from 400 mm to 867 mm continuously for three days. Over 7 lakh buildings were completely damaged and 13 lakh buildings were partially damaged.

In Class VIII and Class IX textbooks we have studied about causes, effects and mitigation strategies of natural and manmade hazards. In this chapter we will discuss about some of the important factors to be considered to construct a building resistant to four natural hazards: earthquake, landslide, cyclone and flood. The cost of natural disasters to lives, property, livelihood and infrastructure have skyrocketed in last few decades, as the world’s population has grown and people have started residing in areas that are vulnerable to natural hazards. The most successful way to mitigate loss of life and property, is to construct buildings that are disaster resistant. This chapter outlines some of the structural safety measures that need to be taken up for constructing desaster resistant buildings.
