Epicenter Location is Undetermined
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 2025/10/14 07:07:31.
Estimated Is for Major Cities

Show All Data | Nighttime Population | Distance [km] |
| 3 | Kitakami,Iwate | 94,000 | Unknown | |
| 3 | Miyako,Iwate | 57,000 | Unknown |
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.
