Predicting Avalanches and Tsunamis

October 25, 2008

Equations, exciting and new
Oh Tsunamis, they’re expecting you
And Math, life’s sweetest reward
Let it float, it floats back to you

soon will be making another run
With Coulomb
promises something for everyone
In the course of a landslide
On Alborón can still be romance

Because Tsunamis won’t hurt anymore
There are open smiles on these friendly shores
It’s Math
Welcome aboard it’s math
Welcome aboard it’s math

Thank you, thank you, we’ll be here all week. Today’s news story was brought to you by Science Direct, and concerns a paper written by E.D. Fernández-Nieto, F. Bouchut, D. Bresch, M.J. Castro Díaz, and A. Mangeney. They took the Savage-Hutter equations, which have already been used for rock avalanches, added some information about the Coulomb friction term (which is related to the fact that when a liquid spills it spreads evenly all over the floor, but when something more solid like sand spills it forms a pile), and used it to examine landslides from the Spanish island of Alborón (Almería). It might even be possible to predict tsunamis, although not necessarily to prevent them.

And if you can’t concentrate on any of that because you have the theme song for The Love Boat stuck in your head, here’s a little something TwoPi and I found when we did a guest post for Our Best Friend Craig on Puntabulous when he was on a cruise:
