The brief
Seismic activity from the 2011 magnitude-9 earthquake in Japan reached the Earth's core. Research indicates that waves traveled nearly 2,900 kilometres to the core before bouncing back to the surface. This interaction resulted in the entire country shifting eastward by approximately six millimetres.
Coverage from CNN, Space Daily, Yahoo, and Scientific American emphasizes the mechanics of this seismic event. Scientific American and CNN focus on the scale of the impact on Japan's landmass, while Space Daily provides technical specifics regarding the wave's travel time and distance. Coverage does not yet specify how this data will be utilized for future seismic monitoring.
Observers are tracking further dissemination of these findings as researchers continue to analyze the historical impact of the 2011 earthquake.
