Distributed earthquake monitoring using laptop accelerometers

Distributed earthquake monitoring using laptop accelerometers

Newer models of laptops manufactured by companies like Apple and Lenovo contain accelerometers — motion sensors meant to detect whether the computer has been dropped. If the computer falls, the hard drive will automatically switch off to protect the user’s data.

“As soon as I knew there were these low-cost sensors inside these accelerometers, I thought it would be perfect to use them to network together and actually record earthquakes,” says geoscientist Elizabeth Cochran of the University of California, Riverside.

So a few years ago, Cochran got in touch with Jesse Lawrence, a colleague at Stanford. They whipped up a program called the Quake-Catcher Network. It’s a free download that runs silently in the background, collecting data from the computer’s accelerometer and waiting to detect an earthquake.

Laptop accelerometers aren’t as sensitive as professional-grade seismometers, so they can only pick up tremors of about magnitude 4.0 and above. But when a laptop does sense a tremor, it’ll ping the researchers’ server. “And when our server receives a bunch of those, we then say, ‘This is a likely earthquake,’ ” Lawrence says.

Lego bricks builders wish they could buy

Lego bricks builders wish they could buy

Anyway, among the many interesting discoveries I’ve made there was a link to the Brick Wishlist Flickr pool, which is a collection of doodles, diagrams, and renderings, made by Lego fans, of elements they wished existed, but do not. These “requests” range from simple color options (as in user d-higdon’s “fall colors” idea for the “leaves” element (#2417), currently available only in green) to what would be, for Lego, anyway, fairly radical departures, like plates with studs on both sides.
