Last night (01-07-2007) in the TV news there was a report on the change of water colour of the rivers in the Sundarbans. Hilsha and other fish started coming up through the stream of the rivers. Salinity has also increased to a great extent. The causes behind this change should be found out immediately. Bangladesh is in a vulnerable zone as far as earthquake is concerned.The following steps could be taken to ascertain the causes behind the sudden change. a) Analyse the water colour in the rivers. b) Water temperature in the rivers and in the Bay may also be recorded. c) An aerial survey can give some clue. d) Some other tests can also be carried out. Our neighbouring countries like India and Myanmar may also be contacted to know their views on the unusual development.
