Earthquake zones

As if people living in the world's major earthquake zones don't have enough to worry about, a new analysis of two of the biggest quakes of the past century reveals a sharp spike in volcanic eruptions after the events, sometimes in volcanoes located hundreds of kilometers from the epicenters. The researchers are quick to point out that not all large earthquakes trigger eruptions, but the work does suggest that in areas where both earthquakes and volcanoes are common, such as in Indonesia, increased volcanic activity could be looming in the wake of big temblors.
The findings make sense. A large earthquake shaking Earth's most active seismic zones with the energy of millions of nuclear bombs is bound to stir up pots of magma deep beneath the surface. Indeed, Charles Darwin speculated about the possibility of volcano-triggered quakes as far back as 1835. And previous studies have linked the two phenomena based on quakes and subsequent eruptions in their proximity. But no one had conducted a long-term analysis or looked at the possibility that big temblors could set off far-away eruptions.
