Web Extras for Chapter 7: Remote Sensing of Volcanoes and Volcanic Hazards

  1. Volcanoes On-Line. The Web is a rich resource of information for volcanoes around the world.|
  2. There are two sites that feature an encyclopedic coverage of world volcanoes big and small. The Smithsonian Institution maintains a website with information related to any of hundreds of volcanoes that have erupted during the past 10,000 years: . The OregonStateUniversity also hosts an excellent website focusing on the world’s volcanoes: . Use one or both sites to find out more about two recently active volcanoes (volcanoes may be specified by your instructor or may be the most recent eruptions listed on the websites). Fill out as much of the table below as you can:

Volcano Name / Location / Type of Volcano / Main Hazards
  1. The United States Geological Survey (USGS) operates a volcanic hazards program and five volcanic observatories whose mission is to monitor and study the nation’s active and potentially active volcanoes. The USGS volcanic hazards web page () includes an excellent guide to volcanic hazards illustrated by real case studies (click on Hazards) and links to the five volcanic observatories, which are rich in excellent photos (click on Observatories).
    Visit the appropriate USGS volcanic observatory web page to research either a volcano near you or one that your instructor specifies. Find out each of the following about your volcano:
    (1) What type of volcano is it (cinder cone, shield, stratovolcano, or another type that you specify)?
    (2) Is it active, dormant, or extinct?
    (3) What are the main hazards represented by your volcano?
    (4) Is there a volcanic hazard map? Do you or someone you know live in a hazard zone? If so, give the type(s) of hazard(s).
  2. Stromboli Online( is a website filled with great photographs, panoramas, and spectacular video clips of many erupting volcanoes around the world. It is worth having speakers attached to your computer when watching the videos to get a sense of the explosive forces associated with eruptions.
    For this exercise, use the images and video clips of the following volcanoes to classify them based on their approximate size and shape and to evaluate their main hazards. To help with this classification, go to and click on Photo glossary to get illustrated definitions of potentially unfamiliar terms. Keep this page open while you browse Stromboli Online.
