NASA Data Show Earthquakes May Quickly Boost Regional Volcanoes

     Scientists using [1]NASA satellite data have found strong evidence
     that a major earthquake can lead to a nearly immediate increase in
     regional volcanic activity.

     [...]

     While scientists have long debated whether earthquakes can trigger
     new volcanic eruptions, this study linked an earthquake to enhanced
     volcanic activity at two ongoing eruptions that were being closely
     monitored by satellite-based sensors on a daily basis.

     [...]

     the researchers believe underground stresses from the earthquake's
     seismic waves likely acted to pump magma -- molten rock beneath the
     surface -- into the conduit to the surface, ultimately increasing
     eruption rates.

   Bottom Line: regional earthquakes have sufficient power to modify the
   intensity of activity at ongoing eruptions. It is still not clear if
   they are able to trigger new volcanic eruptions.
