The Paricutin Volcano
The Paricutin Volcano is a currently dormant volcano in the Mexico State of Michoacán. The volcano resides close to a city named Uruapan and is roughly 321 km west of the capital Mexico City. The Paricutin Volcano is relatively young volcano having surged into existence from the cornfield of famer Dionisio Pulido during the 1940’s. This volcanic eruption presented a unique opportunity for scientists to document the life cycle of volcanos that erupt in this way. Scientist flocked to the area to observe the changes in the environment, and map out every aspect that they could of the volcano.
In 1952, the volcano stood 424 meters high and had damaged a significant amount of land surrounding the volcano. Two towns were destroyed

while another three took heavy damage. There were few casualties during this period. Many people from the region never returned. However, despite its high volcanic activity, the Paricutin has become something of a tourist attraction for the region. People from all over the world come out to climb the volcano and to visit areas that are covered in hardened lava. CNN describes the Paricutin Volcano as one of the Seven Natural Wonders of the World. The Trans Mexican Volcanic Belt The Paricutin Volcano is a part of the Trans Mexican Volcanic Belt.
The belt of volcanos resides through central south Mexico. This belt is over 600 miles long. The famous Sierra Nevada is a part of this volcanic belt. Because of the volcanic activity and rock deposits, soil produced in this region is amongst the most fertile. Many of Mexico’s finest agriculture grows in these regions. The Paricutin Volcano is referred to as a scoria cone volcano. This name is derived from the shape the volcano took while developing. Scoria cone volcanos are renowned for appearing suddenly, creating a cone shaped volcano, with a large inward dome, before going extinct or dormant for long periods of time. The Paricutin Volcano is one of the youngest volcanos in this region. Scoria cone volcanos are the most common type of volcanos in the region. The crater created by the volcano is almost 200 meters across. Tourists are able to easily hike up the volcano and can walk around the perimeter of the crater.
Is the Paricutin Volcano Extinct?
There has been a lot of debate regarding whether the Paricutin Volcano can be classified as extinct. Most scientist will agree that the volcano itself is probably extinct, but the forces that brought upon its creation, are still very active in the area. The volcano itself is still hot, hot enough to react with falling rain water to produce steam from its crater. In the previous years, there has been increased volcanic activity in the area where the Paricutin formed, but the Paricutin hasn’t itself erupted in many years.
The Last Eruption of
Paricutin The last time the Paricutin was erupting was right after its formation. From 1943-1952 the volcano was in a constant phase of eruption. Weeks before the eruption started, earthquake activity was picked up in the surrounding areas. Weeks before the volcano erupted there were a reported 21 earthquakes; however, days before the volcano erupted, the report of earthquakes had spiked into the hundreds. The volcano erupted in four stages throughout the 9 year active period. The formation of the volcano drew attention from around the world and even inspired a children’s book.
First, one must know a little information about this volcano. Mount Shasta is located in Siskiyou County, California. This volcano is the second highest peak in the southern end of the Cascade Range and is still active, though not enough for people to notice. At 14,179 feet it is also the most voluminous stratovolcano located in the Cascade Volcanic Arc. The mountains complex shape is due to the four overlapping volcanic cones it consists of, including the most prominent, main summit, Shastina. The other cones include: Sargents Ridge cone, Misery Hill cone, and Hotlum cone. Sargents Ridge cone is the oldest of all the cones that make up the mountain. Though it is now dissected by a glacial valley, a portion of it can still be seen on the mountain. Misery Hill makes up a large part of the present mountain. the fourth cone, the Hotlum cone is formed from eruptive products and is located on the northeastern side of Mount Shasta. Three of the four major vents on the mountain are aligned with a north trending zone that passes through the mountains summit. This linear alignment parallels local faults, which suggests that the bedrock structure has influenced and partially controlled the dimensions in which Mount Shasta develops (Mie...

Helens tallied up to be the most deadly and destructive eruption the United States had ever seen. “Approximately fifty-seven people were killed directly from the blast and 200 houses, 47 bridges, 15 miles (24 km) of railways and 185 miles (298 km) of highway were destroyed; two people were killed indirectly in accidents that resulted from poor visibility, and two more suffered fatal heart attacks from shoveling ash (Wikipedia 3)”. Just when it seemed the nightmare was over a second eruption occurred the following day. A quarter of the lava was fresh, and included ash, pumice, and volcanic bombs, and the rest was older molten rock. “The removal of the north side of the mountain (13% of the cone 's volume) reduced Mount St. Helens ' height by about 1,280 feet (390 m) and left a crater 1 to 2 miles (2 to 3 km) wide and 2,100 feet (640 m) deep with its north end open in a huge breach (Wikipedia 3)”. The downwind of the eruption also destroyed many agricultural crops such as wheat, apples, potatoes, and alfalfa. Overall Mount St. Helens was a major blow that cost the US 1.1 billion dollars, and struck fear into the hearts of all of America on May 18th,

Like most of the other volcanoes in the Cascade Range, St. Helens is a great cone of rubble, consisting of lava rock interlayered with ash, pumice and other deposits. Volcanic cones of this internal structure are called composite cones or stratovolcanoes. Mount St. Helens includes layers of basalt and andesite through which several domes of dacite lava have erupted. The largest of the dacite domes formed the previous summit; another formed Goat Rocks dome on the northern flank. These were destroyed in St. Helens' 1980 eruption.

...815 eruption of Mount Tambora. With over 70,000 deaths and a rating of 7 on the volcanic exclusivity index, this eruption is one of the largest in recorded history. Not only did this volcano cause destruction in Indonesia but the consequences were further felt around the world, as volcanic ash and sulphuric gases were dumped into the stratosphere causing a global climate shift. Dark clouds covered the sun, and dramatic weather changes ensued. Flash floods frequently occurred wiping out a great deal of crop eventually causing prices to skyrocket. Disease began to spread due to malnourishment and unsanitary living conditions. Eventually these consequences subsided and citizens began to migrate towards Mount Tambora once again. Today the government has placed seismic sensors are set up in the most volatile areas to ensure preparedness in the event of another volcano.
The first time I saw Mt. Rainier for myself, was last summer when my boyfriend and I drove to Washington. It was the most beautiful, peaceful looking mountain I have ever seen. However, underneath it's great beauty, it hides a deadly secret. Mt. Rainier is one of the most dangerous volcanoes that we have here in the United States. One of the reasons it is so dangerous is because of it's great beauty. People enjoy looking at it, and the area that surrounds it, so they have made their homes here. Mt Rainier is not the only volcano I am interested in, in fact this last summer I also went to Mt. St. Helens and Crater Lake. But it is the volcano I chose to research for this paper because it does have so much beauty and at the same time so much power. I already know the basics about volcanoes, how they form, the different types, etc., but I wanted to find out more about what would happen if this great volcano were to erupt, what type of eruption would it be, and how would it affect the people that live around it.
From modern examples and records we know that volcanic activity can set of a chai...
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Volcanism is a major part of the Galapagos and their formation. The island chain is positioned on the Nazca Plate, which is subducting beneath the South American Plate at a geologically rapid pace of 2.5 inches per year. In addition, this Nazca Plate is located directly on top of the Galapagos Hotspot. It is here that mantle plumes melt Earth’s crust, creating volcanoes as a product. The oldest island was first shaped by this ...
The Mauna Loa volcano is located in Hawaii and means "Long Mountain" in Hawaiian. It is a giant, basaltic shield volcano. It is one of the largest volcanoes and mountains in the world and has been called the "monarch of mountains". It has an estimated volume of 9,600 cubic miles and takes up half the land of Hawaii. It extends about 120 km starting from the southern tip of the island to the northern region. It is 97 km (60 miles) long, 48 km (30 miles) wide, and is 8,742 km (28,680 miles) high from the base on the sea floor to the top. The slopes are steeper than 12 degrees and about 4 degrees at the top of the volcano. Mauna Loa formed about half a million years ago and in the middle stages of forming into a shield volcano where lava flows to form a sloped and broad flat domed volcanic cone. Along with Mauna Kea, the Mauna Loa volcano is responsible for the creation of the Hawaiian Islands. Mauna Loa has erupted thirty-three times since 1843 and is known as one of the most active volcanoes in the world today. The last eruption was 1984 and lava flowed within 4 miles of the city of Hilo. This shows that it is dangerous to live anywhere near Mauna Loa and that it poses as a threat to anyone living near it because it has a very high possibility of erupting within a very short span of time. Below is a picture of Mauna Loa taken from a bird's eye view.
Volcanoes can be one of the most destructive forces on Earth. It is estimated that some
The earliest outcropping volcanic deposits date back to about 25,000 years ago. The lavas observed at a -1125 m bore-hole are about 0,3-0,5 million years old. It is known for the first eruption of which an eyewitness account is preserved, in 79 AD. Geologically, Vesuvio is unique for its unusual versatility. Its activity ranging from Hawaiian-style release of liquid lava, fountaining and lava lakes, over Strombolian and Vulcanian activity to violently explosive, plinian events that produce pyroclastic flows and surges.
