Scientists at the National Earthquake Information Center in Golden,
Colorado are pouring over information from the earthquake that hit
northern Japan on Thursday U.S. Time.
Scientists say the quake measured a magnitude 8.0 and it triggered
fires, power blackouts and the evacuation of thousands of homes.
Several aftershocks have been rocking the area since the main quake hit.
Scientists at the Earthquake Information Center say they believe the
quake happened in a relatively shallow area, which is a concern, because
scientists say shallow earthquakes tend to trigger tsunamis that can
cause huge amounts of damage.
There were reports of some smaller waves that hit Japanese land, but no
major wave has been spotted.
Scientists say some tsunamis can travel at speeds of 600-miles per hour.
Aftershocks are expected to continue to hit the area for several more days.
