Volcanology Basics

VOLCANOLOGY BASICS

• • This is a great animation by USGS’ Volcano Disaster Assistance Program and IRIS
    “Volcano seismicity – Generalized model of unrest prior to eruption at long-dormant stratovolcanoes”

 

• What is Real-Time Seismic Amplitude (RSAM)?

• How do I read a seismogram?
  

  Lern how to recognise various earthquakes’ and noise signatures. (PDF from IRIS/UGSS)

 

• Four animations of “Tectonic Settings of Volcanic Activity”:
  1. Continental rift volcanism
  2. Continental volcanic arc
  3. Hot-spot volcanoes
  4. Volcanic-island-arc

• Great: Volcano exercise (game) – test yourself: Would you be able to evacuate and save people’s lives at the right moment? http://www.indiana.edu/~g103/eista/content/volcpred.swf
• Learn what conditions cause what type of eruptions: Build your own (virtual) volcano and watch it erupt!  http://discoverykids.com/games/volcano-explorer/

JUST A LITTLE BIT ADVANCED

• How do Calderas form? Although this paper is about basaltic shield volcanoes, the author goes into all known caldera forming processes in the first part of it. It is written in plain English for anyone to understand who has a will to learn more about volcanoes. Be patient for the PDF to load, it has 178 pages (many of them are illustrations and photos!)
