Is Distribution
Maximum Observed Is:3
Seismic Intensity (Is) distribution is estimated from the observed data (circles) of NIED K-NET, KiK-net, JMA, and local governments that had been collected by 2020/03/28 10:01:25.
Estimated Is for Major Cities
| Max. Obs. Is | Histogram of Estimated Is |
Municipality Show All Data | Daytime Population | Distance [km] |
| 3 | Abira,Yufutsu,Hokkaido | 9,400 | 103 | |
| 3 | Shinhidaka,Hidaka,Hokkaido | 26,000 | 49 | |
| 3 | Hakodate,Hokkaido | 280,000 | 130 | |
| 3 | Chitose,Hokkaido | 93,000 | 115 |
The histogram shows frequency distribution of estimated Is derived from interpolation of the observation with 250-m mesh. The daytime and nighttime correspond to 9:00-18:59 and 19:00-8:59, respectively. The distance is measured from the epicenter to the center of the municipality.
