SCIENCE How smudged crystals offer windows into a volcano’s eruptive past. Crystals in volcanic rocks contain clocks that offer clues to the volcano’s plumbing and past behavior. The technique, called diffusion chronometry, is catching on among volcanologists. It depends on understanding how the crystals grew out of a magma soup deep underground, accreting layers that … More Crystal clocks
When the sun, moon and Earth are aligned, high tidal stress may increase the chances that an earthquake will grow bigger than it otherwise might have been. Listen to the 60 Second-Science podcast at Scientific American.
Rockfalls without an obvious cause (like an earthquake or expanding ice) may be due to hot daily air temperatures expanding small cracks in cliff faces. The floor of Yosemite Valley is littered with piles of rocks that crumbled off the park’s iconic cliffs. These rockfalls happen all the time, because Yosemite’s granite walls are … More Heat ID’d as Subtle Cause of Rockfalls
