Japan upgrades magnitude of killer earthquake to 9.0; USGS keeps number at 8.9

By The Associated Press | The Canadian Press – 1 hour 6 minutes ago

TOKYO - Japan's Meteorological Agency says it has upgraded the magnitude of

Friday's catastrophic earthquake to 9.0.

The agency earlier measured it at 8.8. The quake was already the biggest to hit

Japan since record-keeping began in the late 1800s and one of the biggest ever

recorded in the world.

The agency warned Sunday of more strong aftershocks following the quake, which

unleashed massive tsunamis in northern Japan and killed at least 763 people.

The U.S. Geological Survey has measured the quake at magnitude 8.9, and that

number remained unchanged Sunday.
