Volcano Calendars We have published several volcano calendars over the years: usually, we use photos taken by us or our participants during our recent volcano tours and expeditions. A perfect gift if you're a fan of volcanoes!
Introduction to Plate Tectonics The Earth's upper, rigid layer is broken into several plates which are in constant motion to one another. Most earthquakes and volcanoes occur as result of these plate boundaries.
