The Nemuro-Oki (Nemuro Peninsula Offshore) earthquake (Japanese: 根室半島沖地震, Hepburn: Nemurohantō oki jishin) in scientific literature, occurred on June 17 at 12:55 local time. It struck with an epicenter just off the Nemuro Peninsula in northern Hokkaidō, Japan. It measured 7.8–7.9 on the moment magnitude scale (Mw ),[4] 8.1 on the tsunami magnitude scale (Mt ) and 7.4 on the Japan Meteorological Agency magnitude scale (MJMA ).[5]
The earthquake had a maximum Mercalli intensity of VIII (Severe) and measured 5 on the JMA intensity scale. It also triggered a tsunami with observed heights of nearly 3 meters hitting the coastal regions of Hokkaidō, causing damage. No deaths were recorded but twenty-seven individuals suffered injuries, mostly due to falling objects. The total damage from the earthquake is estimated at US$5 million.[6]
