MISAWA AIR BASE, Japan — An early-morning 6.7-magnitude earthquake caused minor facility damage, but no injuries, Thursday at Misawa, according to base officials.

The quake set off some fire alarms and caused some damage to a building that 35th Fighter Wing personnel use to test aircraft engines, according to wing spokesman Capt. Darrick Lee.

Lee said that personnel were inspecting the building on the flight line, and that the extent of the damage wasn’t immediately available.

The earthquake hit at 6:51 a.m. and was centered off the coast of Iwate Prefecture near the location of the 9.0-magnitude Great East Japan Earthquake that struck on March 11.

Japanese officials warned that 1.5-foot tsunamis were expected following Thursday’s earthquake, but they rescinded the warnings about an hour later.

The earthquake rattled a large portion of northeast Japan, including the island of Hokkaido.
