Precarious Rocks Give Clues to Future Earthquake Movements

A new approach to predict the intensity and direction of earthquakes lies in an unlikely source — 10,000-yearold, improbably balanced rocks. You’ve probably seen pictures of these; they are astounding, seemingly impossible and a little scary. You certainly wouldn’t want to be standing downhill if they toppled over.

These geological features are called Precariously Balanced Rocks or “PBRs.” They are formed slowly when tectonic forces elevate granite rocks from below ground to the surface, and erosion whittles away the softer surrounding materials leaving the unlikely and amazing result.

Earthquake Detection, There’s an App for That!

earthquakeSmartphones have revolutionized the way we work, play, communicate and carry out our day to day lives. Recently, researchers discovered a surprising and potentially life-saving application for this technology: early earthquake detection. This unconventional pocket detector could provide precious seconds for people to take shelter or for utilities to implement emergency shutdown procedures.
