Earth’s Gravity Was Affected By 2011 Japanese Quake
The earthquake that rocked Japan two years ago affected the entire world and not in the way you might be thinking. ESA says that the 2011 Fukushima earthquake had an impact on Earth’s gravity. The agency’s GOCE satellite has been precisely measuring Earth’s gravity for four years. A team of scientists from the Netherlands determined that the quake had ruptured the Earth’s gravity field in the Fukushima area. Strength of gravity varies from place to place anyway on Earth and such earthquakes can deform our planet’s crust and cause tiny changes in local gravity, like in this particular case. And this is interesting; data also revealed that GOCE actually “felt” sound waves from the 9.0 earthquake.
