A powerful 9.0-magnitude earthquake hit Japan on March 11 at 1446 local time (0546 GMT), unleashing massive tsunami waves that crashed into Japan's northeastern coast of Honshu, the largest and main island of Japan, resulting in widespread damage and destruction. According to the Government of Japan (GoJ), as of Wednesday (April 6), 12,554 people are confirmed dead and 15,077 people are reported to be missing. The highest number of deaths reported are in Miyagi prefecture (7,648), followed by Iwate (3,687) and Fukushima (1,158). According to the World Health Organization, 2,869 people were injured. Casualty numbers are likely to increase as officials in some areas have not been able to complete their tally of the missing, according to NHK, and as emergency teams continue to reach and assess affected areas.
