A newspaper article published in the Daily Star (Bangladesh) today (December 23, 2012) by a group of scientists Dr. Maminul Haque Sarker, Giasuddin Ahmed Choudhury, Jakia Akter and Sudipta Kumar Hore. The conclusions drawn from a study based on based on archaeological monuments in the coastal Bangladesh are given below from the article.
"The estimated rates of subsidence for the four monuments are presented in the accompanying matrix. Likely annual rate of subsidence varies from 0.4 to 1.9 mm/yr, with hardly 1 mm/yr to be added or deducted. If the rate of subsidence would be 10 mm/yr or 20 mm/yr, plinth levels of these monuments could be 0.7 to 8.5 m below the TPL, which are far from our observations. It can be concluded with higher confidence that the rate of subsidence or RSLR in the Bengal Delta is within the range of a few mm/yr and not one to two cm/yr."
