64　CO₂ backflow due to rising sea temperatures and acidification accelerates global warming and causes frequent mega earthquakes;

The megacity weight of Tokyo blocked the underground pressurized stress flow that was moving southward from off the Sanriku coast and diverged to Noto

Abstract

It became clear that recent heat waves are caused not only by the effects of fossil fuel consumption but also by an increase in atmospheric CO₂ concentration, which is accelerated by a decrease in the ocean's absorption capacity. In other words, the threat of global warming is moving into the second phase. On the other hand, as a result of analyzing earthquake size and hypocenter distribution in Tohoku, Tokyo and Noto for the past 100 years, it was clarified that the megacity weight increase of Tokyo after 1985 blocked the underground pressurized stress flow from the Tohoku region southward, and the stress flow diverged to the Noto Peninsula side, simultaneously with the frequent occurrence of earthquakes in parallel with the sea level rise. These results indicate that the underground phreatic explosion, which occurs when the pressurized magma rises and ruptures the rock mass, triggers the earthquake. In addition, it is suggested that the Tokyo superload prevents the accumulation of stresses that induce large earthquakes in the Tokyo epicenter and the Nankai Trough.
