Volcanos

Nicaragua is called "the land of lakes and volcanos."

The volcanos here are active.

Indonesian officials say two volcanos erupted Monday, forcing the rerouting of flights and preventing thousands of people who had already been evacuated from returning home.

Iceland is often called the land of ice and fire. It has plenty of ice and glaciers, but is also a geothermal hotspot of bubbling hot water cauldrons, geysers and volcanos. Harnessing all that energy is something Icelanders have been doing for generations, but they're about to take that concept one step further.
