Volcano Observation

With no prolonged periods of inactivity the volcano has continuously built up on itself. The last major eruption took place in 1790 and killed many people and animals, but numbers are unknown4. Starting in 1983 there was a chain of several eruptions that started and have yet to stop pushing lava through a lava tube till it reaches the Pacific Ocean. Over a span of twenty year the flow has

A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also

Anpother factor that can have an impact on the level of hazard posed by a volcano is the type of plate margin on which it occurs. Volcanoes occuring at constructive plate boundaries are usually much less violent than those occuring at destructive plate boundaries. This is because the magma produced by plates moving apart is Basic, and therefoe has a low viscosity, allowing it to flow easily. The lava is produced from a central vent or fissure and erupts regularly but not usually violently. Also,constructive plate boundaries are often found under the sea and create submarine volcanoes, such as along the Mid-Atalntic ridge, so pose few threats to humans. As a result, the hazards posed by volcanoes at constructive plat eboundaries is relatively low. However, the subduction of one plate under another at destrctive plat eboundaries can form an acidic magma chamber, due to the build up of intense heat. Acidic magma is very viscous and resisitant to flow, meaning that there is often a huge build up of pressure, which can result in very violent and dangerous eruptions involving ash and pyroclastic flow. This can pose a a serious hazard. Pyroclastic flowsa are extremely dense, containing toxic gases at very high temperatures, and can move at speeds over 100km/h. The consequences of such an unpredictable hazard can be extremely seruous

This volcano is one of the most active of Mexico and has erupted in fifteen different occasions since the year 1519. The Popocatepelt had a great eruption in the year 1947 and only last December of 1994 registered a great volcanic activity and a quantity Significant gas and ash was thrown by the volcano, before an eminent eruption, nearby villages were evicted. Subsequently, activity was registered in the years 2000, 2005, 2012, 2013, 2014, 2015, and 2016. The volcanic smoke, ash, lava, and small earthquakes continue to reproduce

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The location of the volcano is also important. If it is situated on a constructive plate boundary then it is generally less explosive, and therefore poses different threats to volcanoes situated on a destructive plate boundary. The volcano may also be situated on a hotspot like in Hawaii, where the eruptions aren’t very explosive. Volcanos which aren’t explosive can pose other threats to lava flows though, such as dangerous gases being released. Like in Lake Nyos, Cameroon where 1700 people died.

The Capulin Volcano interestingly enough, is apart of what's known as the Raton-Clayton volcanic field (RCVF), a collected scattering of other volcano's that stretch well over 7,000 square miles. Located in Northeastern New Mexico, the Capulin lies dormante, although some believe extinct, since it's last volcanic activity more than 60,000 years ago. Capulin underwent a rather large eruption that formed its current 1000ft cinder cone shape, which gave way to "a number of small lava flows and cinder eruptions [that] paved over the mound, steepening it's slopes"(NASA, 2016). The base was inital made from the hot ash, cinder, and rock debris of the eruption, and the lava flows themselves were "basalt, deriving from the melting of the mantle" (Sayre and Ort, 2011). Due to

Popocatepetl is an Aztec name that means "Smoking Mountain". According to a research of John Search volcanottive.com, this volcano has been erupted many times, one of the earliest eruptions was between 1345 and 1347. But nothing too dangerous.

Volcanoes are some of the most powerful natural forces known to man. Volcanoes usually form at divergent and convergent boundaries. Sometimes they form in the middle of plates where magma fights through the crust. By understanding volcanoes, scientists get a window to the inside of the Earth. They can also study volcanoes to perhaps get closer to predicting eruptions in the future. One of Earth’s volcanoes is Clear Lake. Clear Lake has unique characteristics such as its location, how it forms, and how it erupts. It had erupted in the past with the potential to erupt again.

In fact, the volcano has a history of being quite active. There has been an eruption of some sort nearly every year since 2001, one of the largest being in 2005 when explosions of lava landed as far as 3-4 kilometers from the site of the Mexican volcano (https://en.wikipedia.org/wiki/Volc%C3%A1n_de_Colima). According to NOAA advisory regarding what is known about the volcano so far active lava flow can be seen coming from the volcano, and clouds of smoke have cause trouble for airports in the area

The active volcano that I chose to research is Popocatepetl volcano. Popocatepetl volcano is an active volcano located in Mexico. The volcano is oftentimes referred to as “El Popo” by many Mexicans. El Popo is a composite cone volcano. Being a composite cone volcano, El Popo is characterized by a steep cone shape, which was created by many composite layers of material pouring out over numerous eruptions. The lava that comes out of El Popo is extremely viscous. The highly viscous lava does not travel very far, and typically cools down rapidly. Scientists believe that El Popo is about 730,000 years old. It has erupted more than 15 times since 1519. In 1994 El Popo produced gas and ash, which caused nearby towns to evacuate. The toxic

Ash plumes and steam rose into the bright blue sky as the underground earthquake shook the land and rattled windows all across the eighteen mile town. As the jet circled the island, in view of lovely beaches and emerald water, looming over this lush paradise was the screaming volcano. Volcanos erupt when the pressure inside of them becomes so great that the magma surges up and forces its way out. An exploding volcano can rip apart a mountain in just seconds, when the eruption is over, a landscape is changed forever. The united states is home to more volcanos than any other country except Indonesia, and Japan. The majority of these volcanoes are in Alaska. Until recently, there was no way to predict when a volcano would blow, although volcanoes give off many warning signs before they erupt. Including smaller earthquakes beneath the volcano, slight inflation, or swelling. The rising magma eventually causes the solid rock to break, sending earthquake signals. Most volcanoes give warning signs beginning weeks or months before they blow (Lindop).

Submarine volcanoes, also known as sea mounts, are underwater landforms that magma releases from. They’re most commonly located near ocean ridges because that’s where the most tectonic plate movement happens therefore, more eruptions. Depending on the depth at which the volcano is, vapor clouds may be visible but usually only in shallow waters. There are two big types of volcanic eruptions, huge lava pockets that release really slowly and and bunch of little lava pockets that burst super fast. There has been a study conducted so that scientists are able to differentiate the types of eruption so that they know
