The last big quake to hit Tokyo was the Great Kanto earthquake, a magnitude-7.9 jolt that struck on Sept. 1, 1923.About 105,0000 were killed in the Tokyo metropolitan area, many of which were caused by crumbling houses and fires that quickly engulfed the city.ccording to the researchers, a large earthquake strikes in proportion to the number of smaller shakes â measuring about magnitude-3 to 5 â that break out in the region. In other words, the more small tremors there are, the greater the probability a devastating one will hit.
