SEISMIC RISK ASSESSMENT OF BUILDINGS IN KOLLAM INDIA

Many earthquakes(EQ) were recorded from coastal margins of Indian peninsula during the last 200 years. The vulnerability of Kerala in India to EQ was highlighted at a meeting of Government and NGOs held recently in association with United Nations Development Fund (UNDP). The entire state is in Zone III, a moderate risk zone. Many cities deserved more attention owing to high concentrations of population. While an EQ cannot be prevented, the damage to life and property can be minimized if effective steps are taken. Each area differs in terms of climate, culture, methods of construction and living standards. Materials used also differ. A localized survey can find out the methods and materials for construction, general pattern of the structures etc. This will enable the identification of damage prone structures during a seismic event. Suitable retrofit measures can also be planned. This study carries out such as survey of Kollam district in Kerala, India. The data was analysed and suitable retrofit measures have been suggested.
