HONSHU & HOKKAIDO, Japan (HawaiiNewsNow) - Two powerful earthquakes shook Japan on Thursday; however they were not strong enough to generate a tsunami threat to Hawaii.
The first quake was measured at a magnitude 6.1, according to the U.S. Geological Survey. It struck just off the coast near the nuclear power plant damaged by the March 11 earthquake and tsunami.
The earthquake happened at 9:24 a.m. Wednesday Hawaii time (Thursday in Japan), about 41 miles east-northeast of Iwaki, Honshu.
The second quake was measured at a magnitude 6.2, and was felt in the Hokkaido region. That hit at 12:25 a.m. Thursday Hawaii time.
About 3,900 households in the towns of Erimo and Samani lost electricity shortly after the quake, but power was restored about an hour later, according to the Hokkaido Electric Power Co.
The shaking was not felt in Tokyo.
The two shakings are believed unrelated and did not affect the crippled Fukushima Dai-ichi plant or other nuclear plants in the region.
