Super Volcanoes by Robin George Andrews
5 out of 10

At any given moment there is volcanic activity somewhere on earth.  There are different clusters and hot spots.  Also, different flavors.  Volcanoes can spew a multitude of chemicals and colors.  The book highlights academic all-stars in the field.  Volcanologists have observatories.  Additionally, they spend a lot of time studying the geological records that show a rich history of flowing lava.  Two areas where research is erupting (you are welcome) involve the use of submarines and spacecraft to explore the ocean floor and celestial bodies.
