The Sound of a Distant Rumble: Using monitoring devices originally intended to pick up the sound of nuke launches, researchers track the underwater noise generated by the December 26 (tsunami) earthquake. Eerie audio file of the slowly-building roar is included on the page. (More info here as well)
Worth picking up if you have a library with a subscription. The May 20th issue of Science was devoted to the Sumatra-Andaman Earthquake of December 24 describing the full power of that event, the most powerful recorded since the deployment of modern electronic sensors. The multiple effects claimed include swarm earthquakes in Alaska, a shock wave that moved every place on Earth a centimeter, and resonant waves continuing weeks after the event. It is also the the longest rupture recorded and took over an hour to complete. Animated simulations of aspects of the event are linked through PhysOrg.com.
Tsunami visualizations Visualizations of recent and historical tsunami episodes, collected by John McDaris at Carleton College. Includes large but visually effective animations, such as this NOAA visualization of the global propagation of the 26/12/04 tsunami (24MB Quicktime).
"Infrasonic Symphony" Intrigued by reports of tsunami-avoidance behavior in Sri Lankan wildlife? Science News offers a timely antidote to simplistic mumbo-jumbo about the "mythical power" of animal earthquake detection with a detailed look at the latest research into low-frequency sound. The Elephant Listening Project is particularly interested in elephant rumblings that produce Rayleigh waves. "Mammals, birds, insects, and spiders can detect Rayleigh waves," notes The Explainer. "Most can feel the movement in their bodies, although some, like snakes and salamanders, put their ears to the ground in order to perceive it."
