The Japanese National Police Agency has officially confirmed 11,004 deaths, 2,778 injured, and 17,339 people missing across eighteen prefectures, as well as over 125,000 buildings damaged or destroyed.
According to Italy's National Institute of Geophysics and Volcanology, the earthquake shifted the Earth's axis by 25 centimeters (9.8 in). This deviation led to a number of small planetary changes, including the length of a day and the tilt of the Earth. The speed of the Earth's rotation increased, shortening the day by 1.8 microseconds due to the redistribution of Earth's mass. The axial shift was caused by the redistribution of mass on the Earth's surface, which changed the planet's moment of inertia. Due to the effects of conservation of angular momentum, such changes of inertia result in small changes to the Earth's rate of rotation.
