The deep drilling involved in geothermal power production can induce earthquakes.

Icarus. The Tower of Babel. We all know what can happen when humans reach too high. Well, apparently reaching too low can also have some negative side effects. In mid-August, a geothermal power plant under construction in Germany set off a trembler that registered at 2.7 on the Richter scale. A similar project in Basel, Switzerland, set off successive earthquakes in 2006 and 2007, one registering as high as 3.4. While some seismic activity has always resulted from geothermal installations, a new process which digs deeper and involves fracturing solid rock, rather than harvesting existing steam beds, both promises to increase power production and, evidently, earthquakes. The news is disheartening, considering that a report from the Department of Energy that came out earlier this year cast geothermal energy as real possibility for significantly reducing our reliance on fossil fuels in a relatively short time frame.

Not Just Invisible, Earthquake Invisible

Architects have, for obvious reasons, been fascinated with earthquakes for as long as they have been knocking over buildings. Lots of structural systems and building materials have been explored, but what about invisibility? Capitalizing on recent advances in invisible cloak technology, scientists in France and Britain think they can hide buildings from those damning shockwaves coursing through the earth. New Scientist explains the tech thusly: Read More
