Recent volcano satellite images
: Browse quickly through the latest satellite imagery from volcanoes all over the world in order to spot ash clouds and hot spots.
: 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.
