Great Tokyo Earthquake

The Great Tokyo Earthquake  (also known as Dead Hole) was an earthquake ten years before the current storyline (to be more precise, April 4th, 2014 at 5:09 pm). The quake rated an 11.4 seismic intensity with 148,000 dead and missing people. It was caused by the power-outburst of the Red Man. The earthquake sank 70% of Tokyo.

A similar earthquake occured when The Red Man massacred the DW Task Force squad. This earthquake was less severe, because the Mother Goose System was still working and The Red Man's power was only at 15%.
