The nature and the distribution of the earthquake events in different seismic zones of the country are intrinsically related to various tectonic elements. The increased frequency of earthquake events in Bangladesh in the last 30 years suggests reviving tectonic activity. In case of severe earthquake and increased probability of earthquakes the risk of loss of life and damage to property in Bangladesh will be quite high. Four severest isk zones in the country are inferred those include northern part of Dinajpur, Rangpur, Mymensmgh, Sylhet, Tangail, northern part of Dhaka, Khulna, Jessor, Kushtia.
Earthquake The first seismic zoning map of the subcontinent was compiled by the Geological Survey of India in The Bangladesh Meteorological Department adopted a seismic zoning map in Inthe Government of Bangladesh constituted a Committee of Experts to examine the seismic problem and make appropriate recommendations.
The Committee proposed a zoning map of Bangladesh in the same year. Zone-2 comprising the central part of Bangladesh Dhaka, Rajshahi, Dinajpur Bogra, Chittagong and Noakhali Districts represents the regions of recent uplifted Pleistocene blocks of the Barind and Madhupur Tracts, and the western extension of the folded belt.
Zone-3 comprising the northern and eastern regions of Bangladesh Sylhet, Mymensingh and Rangpur Districts with the presence of the Dauki Fault system of eastern Sylhet and the deep seated Sylhet Fault, and proximity to the highly disturbed southeastern Assam region with the Jaflong thrust. Naga thrust and Disang thrust, is a zone of high seismic risk with a basic seismic co-efficient of 0.
Northern Bangladesh comprising greater Rangpur and Dinajpur districts is also a region of high seismicity because of the presence of the Jamuna Fault and the proximity to the active east-west running fault and the Main Boundary Fault to the north in India. The Chittagong-Tripura Folded Belt experiences frequent earthquakes, as just to its east is the Burmese Arc where a large number of shallow depth earthquakes originate.
In the modified zoning map, a part of Chittagong area is included to zone- 3 Popular Essays.Earthquake Risk in Bangladesh Only recently have scientists come to recognize that Bangladesh is positioned at the juncture of several active tectonic plate boundaries. Moreover, it sits atop the world’s largest river delta at close to sea level, facing both the risk posed by a quake and secondary risks of tsunamis and flooding in the quake.
For this reason, the earthquake in Bangladesh is a common matter to the people.
We are lucky enough as no severe incident happens in years. Most of the areas in Bangladesh are located on the maximum magnitude zone of the tectonic blocks.
Different level of fault zones in or near Bangladesh are. 1. Bogra fault zone with magnitude level ; 2. Zone-II comprising the central part of Bangladesh vulnerability, risk zones, preparedness, impacts and risk represents the regions of recent uplifted Pleistocene blocks mitigation of earthquake were done.
EARTHQUAKE IN BANGLADESH An earthquake is a sudden, rapid shaking of the Earth caused by the release of energy stored in rocks. It is a natural phenomenon like rain.
It is a natural phenomenon like rain. Global Seismic Hazard Assessment Program There are several major earthquake zones in North America. One of the most notable can be found on Alaska's central coast, extending north to Anchorage and Fairbanks.
Only recently have scientists come to recognize that Bangladesh is positioned at the juncture of several active tectonic plate boundaries.
