Just after 7 pm, local time, a magnitude 6.9 earthquake hit off the east coast of Honshu, Japan.
The tremor prompted evacuation advisories for residents near the coast. A tsunami advisory was also issued for coastal regions, but was dropped about an hour and a half later.
Small tidal changes were recorded on the Pacific coastline, but no damage or injuries have been reported.
A swelling of 20 cm was observed in the port of Hachinohe in Aomori, while smaller changes were observed on Hokkaido Island.
Iwate prefecture was also included in the tsunami warning and was one of the locations significantly damaged by the earthquake and tsunami that devastated the region one year ago.
A series of aftershocks followed Wednesday's earthquake including a magnitude 6.1, which was felt in Tokyo.
