Volcanoes

Volcano in Hawaiian is spelled "lua pele."

There is no known plant species commonly referred to as a "volcano flower." It may be a misconception or a fictional creation, as volcanoes are more associated with destructive eruptions rather than nurturing plant life.

The amount of lava that comes out of a volcano can vary greatly depending on the eruption type and size of the volcano. In general, volcanoes can produce anywhere from a few cubic meters to millions of cubic meters of lava during an eruption. Some eruptions, such as those from shield volcanoes, can produce lava flows that extend for tens of kilometers.

The safety sign of explosive indicates the presence of materials that can produce sudden and violent release of energy. It serves as a warning to keep away from the area and handle with extreme caution to prevent accidents or injuries.

Geologists can make general predictions about the potential power of a volcanic eruption based on the volcano's past behavior, type of volcano, and monitoring data such as seismic activity and gas emissions. However, predicting the exact magnitude and timing of an eruption remains challenging due to the complex and dynamic nature of volcanic systems.

Santorini volcano is on a convergent plate boundary where the African Plate is subducting beneath the Eurasian Plate. This tectonic setting has created volcanic activity in the region, leading to the formation of Santorini island.

Satellites are used to monitor the changes in the shape of the mountains. Specifically this is done rather often on the big island of Hawaii to make sure that none of the two dormant volcanoes (Mauna Loa and Hualalai) are changing shape which would indicate magma movement into the upper Plumbing of the volcanoes. Often times the same type of radar imagery is used to reconstruct the changes throughout a volcanic eruption, this radar imagery service is also used on the Yellowstone Super Caldera. Examples of how this has been used can be seen on both the Hawaii Volcanoes Observatory website and Yellowstone Volcano Observatory website. (See related links).

Yes, there are people who live near Devil's Tower in Wyoming. Nearby towns include Sundance and Hulett, where residents enjoy the natural beauty and recreational opportunities the area has to offer.

Stone Mountain, GA is a result of both constructive and destructive processes. The mountain itself was formed by constructive processes such as volcanic activity and uplift, while the erosion and weathering that have shaped the mountain's current landscape are destructive processes.

Mt Fuji's last major eruption was in 1707. It has been dormant since 1708.

Narcondam in the Andaman and Nicobar Islands is the only known dead volcano in India.

An extinct volcano is one that is not expected to erupt again because it has been dormant for thousands of years. In contrast, an active volcano is one that is currently erupting or has erupted recently.

Mt. Mayon is called a mountain because it is a type of volcano known as a stratovolcano, which is characterized by its steep slopes and symmetrical cone shape. Despite being a volcano, Mt. Mayon is still classified as a mountain due to its physical features and geological formation.

Long Valley Caldera's current volcanic activity level is normal with aviation color code of green. (Updated 2-9-12 CalVO)

This simply means that there is no out of the ordinary activity currently present in the Long Valley Volcanic Complex. For further information on the Long Valley Volcanic System as well as its monthly activity updates see the CalVO (California Volcano Observatory) website in the related links section.

A terrane is the term used to describe a piece of crust that has been in a collision along a convergent crustal boundary and subsequently accreted to another crustal plate. Terranes are distinct geological units with their own history of formation.

This would depend on the type of eruption that Pinatubo were to produce. The only record of eruption of the volcano are of the 1991 event. Although scientists know that the volcano had erupted in an explosive manner before it is unclear what other types of eruptions it can produce. Although unlikely that Pinatubo will erupt in the near future it is a possibility. The eruption is not likely to be as explosive as the 1991 event as the amount of time between eruptions of that magnitude should be longer, given the otherwise unknown history of the volcano. This would suggest that it does not erupt frequently; however, when it erupts it seems to be catastrophic in nature.

Often times in Strato-Volcanoes the "Clearing of the Throat" events before a major eruption are small to moderate ash and steam explosions. These are often times the result of fresh magma that is being injected into the magma chamber and upper plumbing of the volcano interacting with ground water that has accumulated in the volcano.

Possibly what is currently occuring on Kanaga or Cleveland in Alaska (See related links to the current eruptive status of these volcanoes at Alaska Volcanoes Observatory website).

At transform plate boundaries, processes like subduction and seafloor spreading do not occur. Instead, these boundaries are characterized by the sliding past of two tectonic plates horizontally. There is no creation or destruction of crust at transform boundaries, only sideways movement.

Divergent boundary volcanoes are associated with mid-ocean ridges where tectonic plates are moving apart, resulting in upwelling magma forming new crust. These volcanoes tend to produce basaltic lava flows with gentle slopes and low viscosity. Convergent boundary volcanoes occur at subduction zones where one plate is being forced beneath another, leading to the melting of rock and explosive eruptions. These volcanoes typically produce andesitic or rhyolitic magma leading to more explosive eruptions with steep-sided cones.

New volcanic islands have a rich supply of minerals because the volcanic activity brings minerals from deep within the Earth's mantle to the surface during eruptions. These minerals, along with the rapid weathering of volcanic rocks, create nutrient-rich soils that support abundant plant and marine life. Over time, these conditions can yield valuable mineral deposits.

Yes. Activity continued after the 1883 eruption causing a new island, Anak Krakatau, to emerge in 1927 which continues to grow to this day.

Well, after the eruption the lava will cool and harden. Then it will eventually break down into some of the most fertile soil in the world. So people live near or on the volcano for its fertile soil.

Whoever heard of a red-hot volcano in Massachusetts? You would have hard work to find one; in fact, you could not find one today. Yet, we are told by geologists that once upon a time active volcanoes poured out black and red felsites, (which were dense, igneous fire-made rocks consisting of feldspar and quartz) under the sea in Nantasket, Hingham, and Mattapan, Boston.

That was when the famous granites of Quincy and other places on the South Shore welled up from below, and through the interstices or spaces between these came the molten traprock, which was fine-grained, colored, igneous rock in somewhat columnar shape. You can see some of this traprock in the greenish ledges of Cohasset today.

There were so many of these volcanic eruptions, as well as violent earthquakes, that the disgorged materials covered the bottom of Boston's water basin with varied patterns of deposits. Eventually, as we realize, the submarine disturbances quieted down and ceased.

At that time also, the edge of the entire continent along our shoreline was lifted up higher than it is now. You would therefore have had to walk some distance to reach the ocean shore, for it was farther east than at present. All the gravel-formed hills of today were missing, and the ponds and small lakes that we now find everywhere here, simply did not exist.

Blue Hill, just southwest of Quincy, would be perhaps the only place which we of today would recognize if we were whisked by magic back into that distant era. The ancient river, which in those days had for its mouth the area which we call Massachusetts Bay, emptied into the sea somewhere beyond Provincetown. There, deep in the ocean bottom, six hundred or more feet down, still lie the grooves or canyons through which this vast river for ages cut its way oceanward. By then, even the fiery volcanoes which had spewed their molten contents into the Bay, were quenched and dead.

As of 2010, Popocatepetl is erupting. According to the Smithsonian National Museum of Natural History, continuous activity since Jan. 2005 has resulted in phreatic explosions, which occur when molten lava contacts water. In Popocatepetl's case the water inside the crater comes from the heat of the rising magma melting the glaciers on its peak.

A strato-volcano, also known as a composite volcano, is made from alternating layers of solidified lava flows, volcanic ash, and other volcanic debris. These layers are built up over time as the volcano continues to erupt, creating the classic cone shape associated with strato-volcanoes.
