Bangladeshi government has planned to form three separate teams with Bangladeshi army to conduct post- earthquake quick effective charge and rescue operation as earthquakes are often occurred in the country. Bangladeshi Prime Minister Sheikh Hasina Wednesday unveiled the plan that the formats of the teams will be heavy, medium and light to deal with possible calamities after any strong earthquake. The prime minister announced the plan at the equipment handing over ceremony to the Armed Forces Division, Fire Service, Coast Guard and City Corporation in the capital Dhaka. The South Asian country is being hit by light and moderate quakes frequently for which the experts are fearing that the country might be hit by a major tremor. The equipment were collected to use during the post-earthquake and other natural calamities. The Prime Minister said in the future the three teams would provide equipment and training for better operation during any natural calamities. She said the government would provide the financial assistance to build up a strong and effective search and rescue team in the country. Referring to the past rescue operations, Hasina said the rescue equipment of the country is not sufficient to tackle any big disaster. 'That's why we opted for procuring modern and effective rescue equipment,' she said. In Bangladesh most of the multi-storied buildings are not constructed in line with the building code. Earlier on Monday, Bangladeshi Minister for Food and Disaster Management Abdur Rzzaque said at least 250,000 buildings of the country are extremely vulnerable to earthquake and tsunami. Bangladesh is exposed to the calamities as four active sources of earthquake in the Bay of Bengal can generate tremors up to 7- magnitude on the Richter scale, he said, adding that a quake of 6- magnitude may cause massive destructions.
