The earthquake which has devastated Japan has been the focus of many this past week, not the least of which are the scientists who are studying the quake and its subsequent tsunami. Geophysicist Joachim Saul from the GFZ German Research Centre for Geosciences (Helmholtz Association) created an animation which shows the sequence of quakes since March 9.
