The Volcanoes layer (located in the ‘Gallery’ subsection, Volcanoes [in the side bar]) in Google Earth was produced by the Smithsonian Institution under their Global Volcanism Program. The layer is devoted to bettering the understanding of the Earth’s volcanoes, reporting eruptions and keeping a record of volcanic activity as well as providing information such as the volcanoes latitude, longitude, summit elevation and what type of volcano it is.
This layer is another way for the Smithsonian to get their data out to the public in a much more efficient matter. People can simply start Google Earth, find the volcano they are looking for, and then easily view information on that volcano and learn about any recent activity without having to do any searching online.
The Volcanoes layer in Google Earth provides the user with a volcano icon over each volcano (as seen above, and even ones under water, as seen below) that when clicked on provides more information on that specific volcano as well as a picture of the volcano. It should be noted that you need to zoom in a little bit to see most of the volcanoes, however, the larger the volcano the farther out you will be able to see it from.
