Several aftershocks in Japan following large earthquake

Following the 7.6 magnitude earthquake that struck off the northeast coast of Japan on Monday, there have been four strong aftershocks.

The first was a magnitude 5.6 that was 107 km northeast of Kuji, Japan. This was followed by a 4.6 magnitude that was 90 km south of Honchō, Japan, a 5.1 magnitude 93 km east of Mutsu, Japan, and finally a magnitude 4.4 116 km south of Honchō, Japan.

The initial 7.6 magnitude prompted tsunami warnings for the prefectures of Aomori, Hokkaido, and Iwate.

Officials report that over 30 people have been injured.
