An excerpt from an ocean energy distribution forecast map for the 2011 Sendai earthquake, predicting the wave amplitude of tsunamis created by the earthquake.


Overview: Students read selections from the book "The Orphan Tsunami of 1700", by Brian Atwater, about earthquake and tsunami threats detected by scientific sleuthing in mud, trees, and the writings of samurai, merchants, and peasants. As they read, students look for evidence of the scientific process, connections between science and culture, and the role of technology in science.
