"We live on a planet that is still under construction," Donna O'Meara writes, "very day about 50 volcanoes erupt on Earth, adding to the planets topography. Kîlauea volcano is the most active of all of Earth's 1,500 known volcanoes, with over 80 eruptions in the past 200 years."

The Kilauea is famous for it syrupy lava called pahoehoe, seen here.
