This talk explains the geology of earthquakes, the damage scale, and historic losses. It begins by looking in detail at the 1923 Kanto earthquake in Tokyo where 144,000 people died. The martial law imposed afterwards is believed by some to have led to the rise of the Japanese military that led to World War II. The tragedy also resulted in the publication of the outstanding Taisho Shinsai Gashu suite of 25 colored wood-block prints that documented the earthquake which are shown in the presentation. Parallels with the Tohoku-Oki Richter 9 earthquake on March 11, 2011 which resulted in the giant tsunami and the failure of the Fukushima nuclear plant will be discussed. The likelihood of man-made earthquakes will be examined: e.g., fracking generated?

Finally, the August 22nd, 2011, Richter 7 southern Colorado earthquake is reviewed, and an analysis of the consequences of an earthquake along Colorado fault lines will be estimated, e.g., a Richter 6.5 near the Rocky Mountain Arsenal would cause $14.9 billion losses state wide, $5.6 billion loss in Denver County, and 2,500 casualties.
