I would request your kind attention to the Mullaperiyar Dam Issue. We are raising our voice and holding our hands together to get the maximum attention and to avoid the major disaster to our native. Please act to save our state and current lives.
Mullaperiyar Dam is constructed over the headwaters of the Periyar River in 1895 Kerala, India. The area had several geological faults and 20 earthquakes had occurred from July 26 this year in the area. The earthquakes of magnitude of six on the Richter scale had occurred in the State of Kerala. If such a tremour occurred in the vicinity of the Mullaperiyar dam, it would wreck the dam as per the study done by Indian Institute of Technology, Roorkie. The scientists of the Centre for Earth Science here had said that even a quake of magnitude five on the scale could lead to failure of the dam.
The Central Water Commission had said as back as in 1979 that the dam was weak and had recommended lowering of the water level. Though certain strengthening measures had since been done, the foundation was not strengthened. Earthquakes would be affecting the foundation.
Mullaperiyar dam held 15 tmc of water. If it fails, the waters would hit the Vandiperiyar town and flow down to Upputhura and into the Idukki reservoir. The Idukki reservoir hold 70 tmc of water and the Idukki, Kulamavu and Cheruthoni dams would overflow when the water reaches the reservoir. Concrete gravity dams such as Cheruthoni would fail if water overflows. The devastation that this would cause was unimaginable, and no management measures could be thought of for such a tragedy. About 30 lakh people would be killed.
