(CNN) A 7.0 preliminary magnitude earthquake has struck Japan off the coast of Ishinomaki, a city located just 65 miles (104 km) from Fukushima, the site of a devastating 9.0 magnitude quake 10 years ago. A tsunami warning was issued earlier Saturday but has now been downgraded to a "tsunami forecast" of slight changes in sea level, a Japanese government website showed. The US Tsunami Warning System says there is no warning, advisory, watch or threat of tsunami associated with the Japan quake. Japan experienced a deadly quake a decade ago that caused the country's worst nuclear disaster on record. More than 20,000 people died or went missing and a tsunami with 30-foot waves damaged several nuclear reactors in the area.
