Earthquake in Japan shifted the earth’s rotation axis by 10 cm
As a result of the earthquake in Japan on March 11, the Earth’s rotation axis has shifted by almost 10 centimeters(4 inches) It’s the preliminary result of studies carried out by INGV, National Institute of Geophysics and Volcanology.
According to experts, the impact of tremors on the Earth’s axis of rotation was more significant than the earthquake in Sumatra in 2004, , which was 7 cm of linear and two thousandths of an arcsecond angle, and probably second only to Chile earthquake of 1960. The earthquake in Chile last year shifted the Earth’s axis of about 8 cm.
The magnitude of the earthquake epicenter is located 130 kilometers off the coast of Honshu, was 8.9. Tremors triggered a tsunami. Considered the most destructive earthquake in modern Japanese history. Number of victims of the disaster has already exceeded 300 people, and can, according to experts, make up to a thousand people.
The impact of the earthquake that hit Japan this morning shifted the earth’s rotation axis is nearly 10 inches.
The impact of this event on the axis of rotation, said INGV, was also much greater than that of the great Sumatra earthquake of 2004
