6.8 magnitude earthquake stroke Japan on Thursday, causing injuries on 103 people and destroying 31 buildings. According to the U.S. Geological Survey, the earthquake shook north-central Japan. Its epicenter was in the east part of Honshu and began at about 12:26 a.m. (10:26 a.m. ET).

It lasted for nearly 40 seconds, but it was enough to destroy buildings, cause landslides and forced the cancellation of trains in the areas shaken the by the quake, leaving 110,000 passengers affected. Also 6,700 houses were left without electricity after the shake.

There were announced possible aftershocks by the Meteorological Agency official Takashi Yokota and even if the quake was really strong, its center was 111 kilometers below Earth’s surface in the Pacific coast area of northern Iwate Prefecture, as data showed. Still, there was no danger for a tsunami.

Many elderly residents were wounded while they were inside their houses. 200 schools in the four affected prefectures were left with minor damage and no major structural problems seemed to appear.

There was immediately assistance offered by 400 firefighters from Tokyo and other 8 prefectures. Japanese Government decided that the earthquake should be called “Central Iwate Earthquake.”

Last month another earthquake stroke Japan, but it was a 7.2 magnitude and killed nearly 10 people, injuring other 200. June 14 quake meant the disappearance of 12 people who were buried in the rubble of a secluded resort in Miyagi Prefecture.
