Volcano Calendar 2015: We're proud to present our new volcano calendar 2015: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.
Maintaining the volcano and earthquake news sections on this website, the free Volcano Webcams tool and interactive map widget is a free-time, both time- and server cost intensive effort. If you find the information useful and would like to support us, and help keep it alive and improve it, please consider making a small donation. Thank you!
Intraplate volcanism: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
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.
