Lava, Molten Rock, and magma is usually associated as something bad on the ground level.  When a volcano explodes it can cause a lot of damage to both the environment and the population.  In this odd case though these elements are actually helping in preventing something that has killed many more individuals.  Tsunamis.  The article mentions that a Tsunami which most every can remember happened in December of 2004 that killed an enormous amount of people.  Since then scientist have been studying into the ocean seismic activity.  What they found was that lava, molten rock, and magma were actually helping in reducing the amount of earthquakes which would result in tsunamis. 

The molten rock, lava, and magma is helping in a fashion of lubrication.  By lubricating the faults it reduces the chances of earthquake occurrences.  The article mentions that with this lubrication less friction occurs which results in less quakes and less tsunamis.   Although these scientist haven't found how to predict these earthquakes yet these findings are on track to eventually finding out how to predict earthquakes in the future.
