Ending Earthquakes With Water

Relieving stress at fault lines, using fluid injection, could prevent huge earthquakes...

Earthquakes occur at faults, or fractures, in the Earth's crust - where two big slabs of rock meet. Movement under the surface tries to push the rocks past each other but the rough edges get stuck together until enough stress builds up to jerk them past each other - and this violent jerking can cause devastating quakes. But a new instrument, and an experiment in France, has shown that we might actually be able to relieve this stress using fluid injection, as Jean-Philippe Avouac explains to Heather Douglas.
