From: High-resolution 3D earthquake forecasting beneath the greater Tokyo area
These colors show seismicity rate forecasts in the cuboid beneath the Kanto area at 16 June 2018. The units of color legend are event/day/deg3, for a M ≥ 4 earthquake, where ‘deg’ means a degree of global latitude (i.e., 111.11 km). Plus signs are M ≥ 3.0 earthquakes that occurred after the forecast and until November 2018; those with depths from 0 to 15 km are shown on the 10-km plane (a), 16–30 km on the 20-km plane (b), and those with the depths of 5 km above to 10 km below the upper surface of each plate are shown on the plate forecast images (c and d). The contour interval of the rates is ln10, namely about 3 times as large
