Now I suspect if it’s really pollution which killed the fish or if there’s something “geological” happening around the Assam riverbed. If the latter is true, then it means there is a serious trouble which can trigger a scary seismical event near Brahmaputra and Assam.

Thousands of dead fish have been washed ashore in a river in the north-eastern Indian state of Assam river since early this week.

They were discovered on the banks of the Brahmaputra river in the state capital, Guwahati.
An equal number of sick fish were found in the same place, officials said. They blamed rising pollution levels.
An investigation has been ordered by the Assam government, said C.K.Bhuiyan, senior district official in Guwahati.
Earlier in the year, the Assam Pollution Control Board (APCB) told all the oil refineries in the state to achieve “zero pollution” levels by 31 December, otherwise they would be threatened with closure.

The Guwahati refinery was found to be the worst polluting refinery and was perhaps the only one in Assam not to have yet complied, pollution control board officials said.
