Historically Active Volcanoes

Improved Essays
Volcanoes have been around for centuries but, some are active, some are not. Some volcanoes erupt frequently, while others do not. “At least 20 volcanoes will probably be erupting as you read these words” (Siebert 58). We have all heard of volcanoes before but do you really know about them?

A preferred title for “active volcanoes” is a “Holocene volcano” or “historically active.” There are even Holocene volcanoes on the sea floor, and some Holocene volcanoes go way back such as Italy’s Stromboli, this volcano has been erupting for over a thousand years! Holocene means the past 10,000 thousand years and there have been roughly 1,300 eruptions since then and maybe even 1,500. No one is certain how many volcanoes there are but it is predicted

    Because of this, the volcano and its research station often appear in the news. One such time was in a news article called “Underwater Volcano Offers Rare Look at Eruption in Real Time”, written by Nadia Drake from National Geographic. The article spoke of how the volcano's location, surroundings, etc, help geologists learn more and more each day about volcanoes and how to forecast their eruptions. The article later states that a geophysicist at the University of North Carolina says, “We can understand these simple systems first, and then move to more complex volcanoes and apply similar ideas.”…

    The word volcano typically brings to mind a mountain with fire spewing forth from the summit. Therefore, a “supervolcano” would be a massive fire breathing mountain but, this is not the case. Most of Yellowstone National Park and some of the surrounding area is a “supervolcano”. While some of the largest volcanic eruptions have come from Yellowstone, it is not the only place these “mega-eruptions” have occurred There have been “mega-eruptions” in Indonesia, Chile, New Zealand, Argentina, Japan and elsewhere in the United States. “Supervolcanoes” are supermassive, deadly, and have left geological evidence of their destruction all over the world.…

    “Volcanic eruptions are the most awesome and powerful display of nature’s force” (Sigurdsson et al. 2) is a quote from the author Haraldur Sigurdsson that describes the breathtaking sight one may behold from the experience of witnessing the eruption of a volcano. However, innumerable aspects contribute to this gorgeous display. The fascinating eruption varies vastly depending upon numerous factors working within a volcano, and the shapes of volcanoes may affect the way an environment copes with an eruption and may cause volcanic lava and debris to travel in differing paths. Location also plays an important role in the sight and composition of volcanoes, because different regions contain various types of volcanoes. The most important factor…
