December 2011

Volume 64, Issue 12

cover: The 2011 Tohoku-oki earthquake occurred along the megathrust fault where the Pacific Plate subducts under Japan. But the seismic, tsunami, and atmospheric waves generated by the fault rupture were detected worldwide. The tsunami, for instance, devastated coastal villages of northeastern Japan, but it spread seaward as well, as shown in this map of calculated maximum wave heights across the Pacific Ocean. To learn more about the huge event, see the article by Thorne Lay and Hiroo Kanamori on page 33. (Image courtesy of NOAA.)
