Figure 2. Guided by the searing experience of the 2011 magnitude 9.0 Tōhoku shock, which had a magnitude much larger than anticipated by the Central Disaster Prevention Council (CDPC), the Japanese government greatly expanded the hypothetical maximum rupture area of a Nankai Trough megathrust earthquake, extending its southwestern end to Miyazaki, site of the 2024 magnitude 7.1 shock. The upper left image shows the projected shaking of the largest expected event (magnitude 8.6) as calculated in 2003. The bottom right image shows the expected shaking of the largest expected event (magnitude 9.1) as updated in 2012. Shaking follows the Shindo intensity scale. Credit: Modified from CDPC (2012)
