        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "A diatreme, sometimes known as a maar-diatreme volcano, is a volcanic pipe formed by a gaseous explosion.  When magma rises up through a crack in the Earth's crust and makes contact with a shallow body of ground water, rapid expansion of heated water vapor and volcanic gases can cause a series of explosions.  A relatively shallow crater is left (known as a maar) and a rock filled fracture (the actual diatreme) in the Earth's crust." ] ,
