How deep are earthquakes within 250 km of Sapporo?

Where can I get official earthquake information for Japan?
For official information, warnings and safety advice, follow Japan Meteorological Agency (https://www.jma.go.jp/jma/indexe.html) and your local civil protection authority. This site compiles agency reports and is not a warning service.
Can earthquakes be predicted?
No. Scientists can estimate how likely strong shaking is in a region over years or decades, but no method predicts the time, place and size of a specific earthquake. Aftershocks are expected after large earthquakes and become less frequent over time.
