That's pretty big. It's in Hokkaido, I don't if any big population centers are nearby. Most of the big cities are on the main island, Honshu.The U.S. Geological Survey measured the quake at 8.0 but authorities in Japan gave it a magnitude of 7.8.

8.5 is pretty huge.A SECOND earthquake rocked southern Siberia today, causing heavy damage in parts of the Altai republic and prompting officials to declare a state of emergency.
Neither quake, which had their epicentres deep underground in Russia's Altai republic, caused any deaths, but the second earthquake, which had an estimated magnitude of between five and six, caused considerable damage, the Emergency Situations Ministry said.
It followed a quake yesterday that had a magnitude of 8.5, but an epicentre that was 33km underground.
Don't they mean focus? Isn't the epicentre, by definition, at the surface?It followed a quake yesterday that had a magnitude of 8.5, but an epicentre that was 33km underground.

The epicenter is the point on the surface directly above the hypocenter.
