With growing earthquake detection network and superfast computers, geoscientists are now able to explore the Earth's interior, a region that has been more inaccessible than the deepest ocean or the farthest planet in our solar system. Princeton geosciences professor Jeroen Tromp and his team have embarked on an ambitious project to use earthquakes to map the structure of the Earth.
Published on the Princeton University Facebook account this morning was Prof. Jeroen Tromp's statement on yesterday's Virginia earthquake. Appearing along side the statement was a Global ShakeMovie documenting the earthquake and an array of comments coming in from all facets of Facebook life.
