At these locations the magma is able to rise closer to the earth’s surface and heat the water trapped in rock layers. This water is usually only one or two miles [2 to 3 km] below the surface of the ground, well within the reach of modern drilling techniques.
Šajās vietās magma paceļas tuvāk zemes virskārtai un sasilda ūdeni, kas atrodas iežos, parasti tikai kādu divu trīs kilometru dziļumā, un ir sasniedzams ar modernām urbšanas iekārtām.
