Popular Science for November 2011 (page 91) reported that the 2008 earthquake in china's Sichuan province that left nearly 5 million people homeless was caused by the water behind the dam pressing on a seismic fault line. Concerned citizens have raised concerns of similar earthquake pricipitation by the construction of a potential huge multi-billion dollar dam on Alaska's Susitna River-an area known to be in an active geological fault prone region not too far from the National earthquake Data Center office Alaska branch facility.

Gov. Parnell signs legislation to fund Susitna Dam study

A few Alaskans have experienced the decade of problems to Columbia River fisheries created by Columbia river hydroelectric dam building and have offered alternative ideas for providing energy for the Fairbanks to Anchorage region. The area has rich geothermal potential, wind, solar and hydrogen fuel cell sub-station possibilities that could be made far less likwely to devastate fish habitat, game units or stimulate devastating Earthquakes and downriver floods. Of course dam building is as old as beaver technology so its hard to get politicians to move into new and less harmfell methods of producing energy.

A Susitna river dam may significantly alter wieght upon crustal plates, accellerate global warming, alter oxygen levels in the river and impede the migration of fish. Fish generally hate to go up fish ladders that politicians like to extoll as the express lane for easy fish travel.
