Warm or Steaming Ground
Modern Geothermal Features

Warm or steaming ground is often an indicator of a geothermal system beneath the surface. In some cases a geothermal system may not show any visible evidence on the surface, however after a rain fall water may seep beneath the surface, get heated, and rise from the ground as steam. A classic example of this is at the Svartsengi Geothermal Area in Iceland, where the Blue Lagoon is located. The Geothermal area was unknown until the 1960’s when local people observed steam rising from the ground after rainfalls.
