- Vulcanologists classify volcanoes into three groups: active, dormant and extinct. A dormant volcano is one that isn’t currently active or erupting, but geologists think that it’s still capable of erupting.Mount St. Helens erupting.One of the best examples of a dormant volcano is Mauna Kea, one of the five volcanoes that make up the Big Island of Hawaii.The peak of Mauna Kea is 4,207 meters above sea level, but 10,203 meters above the base of the floor of the Pacific Ocean. dormant volcano is one that isn’t currently active or erupting, but geologists think that it’s still capable of erupting.

Volcano Stratovolcanoes or composite volcanoes are tall conical mountains composed of lava flows and other ejecta in alternate layers, the strata that gives rise to the name. Stratovolcanoes are also known as composite volcanoes because they are created from multiple structures during different kinds of eruptions.trato/composite volcanoes are made of cinders, ash, and lava. Cinders and ash pile on top of each other, lava flows on top of the ash, where it cools and hardens, and then the process repeats. Classic examples include Mt. Fuji in Japan, Mayon Volcano in the Philippines, and Mount Vesuvius and Stromboli in Italy.

- The result is that a trail of volcanoes is left behind, with older volcanoes moving away from the hot spot, and newer ones forming over top of the hot spot. .menuItem { font-family: verdana; font-size: 10pt; color: #990000; text-decoration: none; }. One of the most famous hot spots on Earth are the Hawaiian Islands. The oldest islands found in the Hawaiian Island chain consist of mostly dead volcanoes. These volcanoes were active millions of years ago, but the moving crust of the ocean floor has carried them away the hot spot that feed the volcanoes.

Yellowstone hotspot It created the eastern Snake River Plain through a succession of caldera forming eruptions. The resulting calderas include the Island Park Caldera, the Henry's Fork Caldera, and the Bruneau-Jarbidge caldera.The hotspot currently lies under the Yellowstone Caldera.The hotspot's most recent supereruption, known as the Lava Creek eruption, took place 640,000 years ago and created the Lava Creek Tuff and the Yellowstone Caldera.he Island Park Caldera is sometimes referred to as the First Phase Yellowstone Caldera or the Huckleberry Ridge Caldera. The youngest of the hotspot calderas, the Yellowstone Caldera, formed 640,000 years ago and is about 34 miles (55 km) by 45 miles (72 km) wide.

"A ""hotspot"" is an area in the Earthâs mantle from which hot plumes rise upward, forming volcanoes on the overlying crust." A hotspot is theorized to form as one of Earth's outer tectonic plates moves over an unusually hot part of the Earth's mantle and large amounts of magma rise up, piercing through the plates and producing large volcanic eruptions at the Earth’s surface.

Volcanic Eruptions Volcanic Eruptions. A volcanic eruption occurs when molten rock, ash and steam pour through a vent in the earth's crust. Volcanoes are described as active (in eruption), dormant (not erupting at the present time), or extinct (having ceased eruption; no longer active). Some volcanoes explode.Others are slow-flowing fountains of lava, which is hot fluid rock. The following are examples of famous volcanic eruptions.olcanoes are described as active (in eruption), dormant (not erupting at the present time), or extinct (having ceased eruption; no longer active). Some volcanoes explode. Others are slow-flowing fountains of lava, which is hot fluid rock.

- The magma rises through the continent to form volcanoes. VIII. Hot Spot Volcanoes Hot spot- is an area where material from deep within the mantle rises and then melts forming magma. Hot spot can be near plate boundaries or in the middle of a plate. IX. Hot Spot Tectonic Settings and Volcanic ActivityAnimation A volcano forms above a hot spot when magma erupts through the crust and reaches the surface. As the plate moves, new volcanoes will form over the Hot Spot.

CHAPTER A hot spot trail is the result of a plate moving over a stationary hot spot. Only the volcanoes near the hot spot. Those away from it in the direction of the plate's movement … are extinct. A volcanic island arc is a chain of volcanoes that forms at a subduction zone, where one oceanic plate slides beneath another.s a tectonic process where two plates (an Oceanic plate and a Continental plate) collide. In Continental Arc environments the weaker oceanic plate always sub ducts under the … stronger Continental plate.

Hotspot (geology) In geology, the places known as hotspots or hot spots are volcanic regions thought to be fed by underlying mantle that is anomalously hot compared with the surrounding mantle. They may be on, near to, or far from tectonic plate boundaries. Currently, there are two hypotheses that attempt to explain their origins.

- Volcanoes come in all shapes and sizes. The more common types are shield volcanoes, stratovolcanoes, and cinder cones. Shield volcanoes gained their name from the fact that their profile against the horizon looks like a shield laying on the ground. The flanks of a shield volcano have low slopes, sometimes only a few degrees from horizontal. Shield volcanoes are the largest volcanic features on earth. The largest shield volcano, Mauna Loa in the Hawaiian Islands, has a volume 300 times greater than that of the largest stratovolcano, Mount Fuji in Japan.

Volcano This magma tends to be extremely viscous because of its high silica content, so it often does not attain the surface but cools and solidifies at depth. When it does reach the surface, however, a volcano is formed. Typical examples are Mount Etna and the volcanoes in the Pacific Ring of Fire. Hotspots

Hawaiian eruption Very little amounts of volcanic ash are produced. This type of eruption occurs most often at hotspot volcanoes such as Kīlauea and Iceland, though it can occur near subduction zones (e.g. Medicine Lake Volcano in California, United States) and rift zones.awaiian eruptions may occur along fissure vents, such as during the eruption of Mauna Loa Volcano in 1950, or at a central vent, such as during the 1959 eruption in Kīlauea Iki Crater, which created a lava fountain 580 meters (1,900 ft) high and formed a 38-meter cone named Pu ʻ u Pua ʻ i.

VOLCANOES Famous examples of composite cones are Mayon Volcano, Philippines, Mount Fuji in Japan, and Mount Rainier, Washington, U.S.A. Some composite volcanoes attain two to three thousand meters in height above their bases.t is the highest mountain on earth. Shield volcanoes are large volcanoes with broad summit areas and low-sloping sides (shield shape) because the extruded products are mainly low viscosity basaltic lava flows. A good example of a shield volcano is the Island of Hawaii (the Big Island).

- Most volcanoes occur around the edges of the tectonic plates. Hot spot volcanoes are different because they do not occur near the edges of a plate, but rather occur at quite a distance from the edges. The movement of these hot spots volcanoes can be tracked as well.ot spots often erupt continually and the lava creates basaltic rocks. There are cases in which the eruptions of hot spot volcanoes can be very explosive. This is due to the strength and weight of the rock and earth covering the volcano's mouth and the pressure accumulated by a lack of escape routes.
