Geological Hazards are naturally occurring or man-made geologic conditions capable of causing injuries or other health impacts, loss of property damage, loss of livelihoods and services, social and economic disruption, or environmental damage. It had been divided into many types. The two main types of man-made geological hazards are collapsing of buildings and forest fire which happening recently. Now, I’m going to talk about the collapsing of buildings first. The structure of a building actually is fundamental to ensuring the safety of people in or around the existing buildings. However, human’s ignorance, negligence and greed lead to building collapse.
Human ignorance has to do with when incompetent personnel are in charge of design, construction or inspection. One of the major areas of negligence is in specification writing where that of a past project is adopted without crosschecking those areas that need improvement, addition or omission. Greed on the part of building contractors like diversion of building materials, cement in particular, the use of sub- standard materials so as to achieve high profit. Moreover, foundation problems, quality management, material and testing variability and unprofessional conduct will also leads to building collapse.
The effect of building collapse are the innocent citizens lost their life, many other people has been rendered permanent disable in one form or the other as a result of increasing rate of building collapse in the country. Economic problem of this incidence is immeasurable in that many have been rendered homeless with loss of countless properties.
Here is the true incident which happens in Bangladesh when 24 April 2013. At least 76 garment workers have been confirmed dead in Bangladesh after an eight-story building containing clothing manufacturing units collapsed. Moreover, this is another true incident collapse of a 20-metre lighting arrester pole from the UMNO building in Jalan Macalister
