[Rockhounds] Drillers break into magma chamber

[Kreigh Tomaszewski]

It has been described as a geologist's dream - a unique opportunity to 
study up close the volcanic processes that built the Earth's continents.

Drillers looking for geothermal energy in Hawaii have inadvertently put 
a well right into a magma chamber.

Molten rock pushed back up the borehole several metres before 
solidifying, making it perfectly safe to study.
