This is the last in a series of investigative reports from the Chunichi Shimbun about how figures for the probability of a Nankai Trough earthquake were manipulated for a government expert panel report released in February 2018.
When a government panel of earthquake prediction experts revised the probability of the Nankai Trough earthquake scenario from “about 70 percent” to “between 70 and 80 percent” in February 2018, some pointed out that the figure was inflated. The minutes of previous meetings in 2012 and 2013, obtained by the Chunichi Shimbun, revealed the figure had been slammed as “unscientific” at the time.
The seismologists were of the opinion that the probability was not being presented fairly and called for the release of not only the highest figure but a low one as well.
