Earthquake Risks in Bangladesh and Evaluation of Awareness among the University Students

Earthquake is one of the major threats for Bangladesh for decades. In this study, we have tried to investigate the level of awareness about the earthquake among the university students in Bangladesh. Firstly, we have briefly discussed the risks of earthquake in Bangladesh, talked about the historic earthquakes and recently found threat or research. After that, we have analyzed our data collected from the survey we have conducted. We have got some positive results as well as a few horrifying scenarios. Encouraging results have found when we have asked some important matters that everyone should know about earthquake. But knowledge about the safety in the construction of the buildings and following the rules is quite opposite to that. Suggestions are offered in some definite sectors where improvement is required, and the government should push themselves harder in those sectors. of a large amount of sedimentary pile within the Bogra graben [5]. Tripura is one of the states of India surrounded by Bangladesh and two other states Mizoram and Assam of India surrounded by Koplili fault; Kaladan fault etc. which have produced many earthquakes. The Tripura-Naga organic belt is a zone of highly faulted tertiary deposits which has witnessed earthquakes of moderate magnitudes [2]. Shillong plateau is a geologically complex and seismically active region located on the collision boundary between Indian and Eurasian plate in the Meghalaya state of India. Its average altitude is about 1,500 m. The 1897 Ms. 8.0 Great Assam earthquake is well-known as a historic earthquake that occurred below the Shillong Plateau. The Shillong plateau presently behaves like a rigid body tied to the Indian Shield at a velocity of 46.5 ± 1 mm/a toward N 51o E [2,5]. Dauki fault zone is a 300 km long north dipping reverse fault along the Meghalaya-Bangladesh border and inferred to go through the southern margin of Shillong plateau and has a major role in deforming the surrounding areas. It is believed to be active in the past and it is most likely the fault associated with the magnitude >7 earthquake in Sylhet (Shilchar) historically known as Cachar earthquake (10 January 1869). Though it is inactive in the recent times still it is considered as one of the major threats for Bangladesh for the occurrence of devastating earthquakes [6]. A recent study reveals the existence of subduction zone of about 250 kilometers that can produce an earthquake of magnitude 8.2-9.0. After setting two dozen ground-positioning (GPS) instruments linked to satellites, capable of tracking tiny ground motions and analyzing the ten years of data the scientists have shown that eastern Bangladesh and a bit of eastern India are pushing diagonally into western Myanmar at a rapid clip46 millimeter per year or about 1.8 inches.
