A Russian geopolitical analyst says the best way to attack the United States is to detonate nuclear weapons to trigger a supervolcano at Yellowstone National Park or along the San Andreas fault line on California's coast.

The president of the Academy of Geopolitical Problems based in Moscow, Konstantin Sivkov said in an article for a Russian trade newspaper on Wednesday, VPK News, that Russia needed to increase its military weapons and strategies against the "West" which was "moving to the borders or Russia".

He has a conspiracy theory that NATO - a political and military alliance which counts the US, UK, Canada and many countries in western Europe as members - was amassing strength against Russia and the only way to combat that problem was to attack America's vulnerabilities to ensure a "complete destruction of the enemy".

"Geologists believe that the Yellowstone supervolcano could explode at any moment. There are signs of growing activity there. Therefore it suffices to push the relatively small, for example the impact of the munition megaton class to initiate an eruption. The consequences will be catastrophic for the United States - a country just disappears," he said.
