Earthquakes near Koto in numbers
114 earthquakes have been recorded within 300 km of Koto in the last 12 months, the largest M6.8, 22 km SW of Koto, on 28 Jul 2026, 07:27 UTC (16:27 JST).
71 of them were magnitude 4 or above — the level at which people nearby usually feel an earthquake clearly. Smaller ones are mostly recorded by instruments and noticed by few people, if any.
Before 9 August 2026 these counts come from the USGS catalogue at magnitude 2.5 and above. Since then we also read EMSC and national networks, which record smaller earthquakes too, so recent weeks can show more small events than earlier ones.
Distances are measured from the centre of Koto. Whether an earthquake is felt depends on its magnitude, its depth and the ground, so a small shallow earthquake close by can be felt more than a larger deep one further away.
What to do in an earthquake
Drop to your hands and knees, take cover under a sturdy table, and hold on until the shaking stops. Do not run outside during shaking — most injuries come from falling objects and debris near doorways and walls.
