Compilation of learning resources related to the 2011 Earthquake in Japan. Includes interactive timelines, visualizations, and lessons on tsunamis, earthquakes, and nuclear energy.
In this interactive world map from NOVA Online explore nine key tsunamis dating from 3.5 billion years ago and discover what experts have learned from studying them.
Introduction to fundamental concepts in "continuous" applied mathematics. Extensive use of demonstrational software. Discussion of computational and modeling issues. Nonlinear dynamical systems; nonlinear waves; diffusion; stability; characteristics; nonlinear steepening, breaking and shock formation; conservation laws; first-order partial differential equations; finite differences; numerical stability; etc. Applications to traffic problems, flows in rivers, internal waves, mechanical vibrations and other problems in the physical world.
This interactive feature story is part of Science Bulletins, an innovative online and exhibition program that offers the public a window into the excitement of scientific discovery. Published in October 2005, this Earth Bulletin looks at the causes of tsunamis and how researchers are trying to reduce their risk. It includes the following components: Three online essays: Ghosts of Tsunamis Past, From Math to Maps, Fear the Future Tsunami?; A seven-minute feature video, Tsunami Science: Reducing the Risk, available in two download speeds and as a printed transcript; An interactive that shows the creation and path of this atypical wave; An interactive that shows the effects of the December 26, 2004 tsunami on Sumatra's Aceh Province; An interactive that looks at eight history-making tsunamis; A one-minute video, Making Waves to Save Lives, available in two download speeds.
This site uses animation and virtual reality to show how tsunamis are generated by earthquakes. Learn about tsunami research and mitigation efforts -- how sediments are transported by a tsunami, how researchers decipher the geologic record of prehistoric tsunamis, and the seismograph network of the west coast tsunami warning system.
