Volcanology is a geological science that deals with the correlation between volcanic activity and earthquakes, as well as plate tectonics and mountain formation. Geologists that study in this field are called volcanologists. They collect and study data about eruptions to attempt to forecast future occurrences. Volcanologists seek out ore deposits and map out their locations, especially sulfide mineral deposits. The interest in volcanoes dates back to Mt. Vesuvius and its 79 AD eruption, recorded by Pliny the Younger.

  • Q:

    How do shield volcanoes erupt?

    A:

    Shield volcanoes usually erupt with splattering liquid lava that fountains out and has little explosive potential. This forms some of the largest volcanoes on Earth with very gentle slopes, since the liquid water cannot build steeper slopes. This type of lava cools to form basalt rock.

  • Q:

    Where does lava come from?

    A:

    According to the American Geophysical Union, lava forms in the Earth's mantle and flows to the surface through volcanoes. Internal gas pressure within the volcano causes it to spew lava with the amount of pressure depending on how much and how quickly.
