In this section you will watch three examples of explosive volcanic eruptions and record your observations in the group field notebook. As you make your observations recall some of the details that Pliny the Younger wrote down when he witnessed the 79 AD eruption. The video clips that you will watch are from explosive eruptions of the Soufriere Hills volcano on the island of Montserrat in the West Indies in the late 1990's. Many of the eruptions of this volcano are similar to the event that took place at Vesuvius and thus serve as excellent examples to understand explosive volcanism in general. Video clips are provided courtesy of David Lea (Living Letters Productions).
What is an explosive eruption?
For each eruption do the following:
  1. Watch the video clip
  2. Examine the effects of the eruption on the surrounding countryside
  3. Compare and contrast the style and effects of the three different eruptions in your field notebook under task 1.
Make sure that you watch all three eruption videos and complete your observations and comparisons of the eruptions in your field notebook
