Volcanos are deadly, can form on islands or mainland, and can destroy mountains and cities. Volcanos commonly form from holes in the earth containing magma. When pressure builds up in these magma chambers, they explode resulting in magma and rock catapulting out into the air. As these volcanoes repeatedly explode, they leak magma, which runs down the side of the volcano. Eventually, the lava cools and transforms into solid rock, building up the volcano to mountain size. An example of giant volcanic eruptions is the Pompeii disaster in 79AD, when Mount Vesuvius erupted and destroyed all of Pompeii. Another example includes, the 1980 eruption of Mount St. Helens in Washington state, which destroyed the whole mountain. Volcanos

Normally, lava was able to flow out cracks or also known as vents in the mountain closing. But one day, Lava was building pressure on Mount St. Helens. At the end of April 1980, Mount St. Helens began to grow silently. Swelling was spotted on the

It was May 18th, 1980. The eruption of Mount St. Helens occurred in Washington,United States. The exact time it had happened is at 8:32:17. The eruption happened 96 miles out South of Seattle, Washington and 50 miles northeast of Portland,Oregon. Many people died during this time. About 50 people had died. 250 homes were destroyed. Along with 47 bridges, 15 miles of railways, 185 miles of highway was also destroyed. Many tiny earthquakes had happened a couple days before the eruption had happened.

With rent to own homes available you will definitely want to come join the crowd during the annual Kiwanis parade in June or become a part of the big Annual Celebration in September.

Voted the second most beautiful vista in America, Mount Washington is a well-known overlook of downtown Pittsburgh. Mount Washington, now a beautiful mountain with a tree covered Cliffside, was not always known for its sights. Many are unaware of the dirty environment that it used to be. Once known as Coal Hill, Mount Washington was the location of many coal mines. Back in the late 1800’s, this mountain was the source that fueled and built Pittsburgh. From the ravaging coal minds to the breathtaking Inclines, there is a lot of history that is hidden under the beautiful area which we now know as Mount Washington.

Senator Peter Norbeck was Mount Rushmore's great political patron and promoter of the construction of the giant structure. Norbeck helped raise almost a million dollars for the project during the years of the Great Depression.

Mount St Helens erupted on the 18th May 1980 at 9am and is an active strata volcano Washington State USA, a MEDC. Where as on 18th July 1995, during the daytime, Montserrat, a LEDC during the day, Montserrat's Soufrière Hills composite volcano of a height 1050m, meaning sulphur hills, dormant for centuries, erupted and produced a phreatic eruption. The volcano is a strata volcano also. Mount St. Helens is a composite volcano which lies near to a destructive plate boundary where the small Juan de Fuca Plate is being subducted underneath the North American Plate where as the eruption

Mount St. Helen is a very active volcano classified as a stratovolcano, stratovolcano is basically a tall volcano built up of layer after layer of hard lava, tephra, pumice, and volcanic ash. Mount St. Helens location is in Skamania County in Washington, with coordinates of 46 12'00.17"N122 11'21.13"W. Mount St Helen is famous because of its catastrophic eruption on May eighteenth in nineteen eighty. The eruption measured a five on the volcanic explosivity index. This is an index created by Chris Newell and Steven Self in the year nineteen eighty-two it was designed to try and measure the explosiveness of volcano eruptions to determine the value of the explosivity and qualitative observations ranging from zero to eight, eight being the

Stone mountain has remained a very influential monument of Georgia; a gem of what may say to the state’s tourism and a landmark of American history throughout the ages. Stonewall Jackson, Robert E. Lee , and Jefferson Davis on top of their valuable steeds represent the Confederate nation and its tie with Stone mountain as they are carved meticulously in the world’s largest exposed granite; however, the peaceful serenity of the lake and nature that envelops the mountain and its visitors remained a very important ceremonial location for native americans. The complete history of Stone Mountain is interwoven into the treads of historical events that have occurred throughout and even before the great nation , United States of America, was formed. Currently, it’s one of the most famous attractions in Georgia known for the breathtaking view of metropolitan Atlanta at the peak of the mountain. It is clear as rich as the beauty of stone mountain is,undeniably, it has a strong historical importance to American history and exquisite backround.

Throughout history, great importance has been placed on the existence of God. Every civilization through time has sought some sort of reassurance that their is a higher being the watches over humanity. The evidence of this belief can be seen in the tombs of the Egyptians, in the sculptures of the Greeks and in the customs of the African tribes, among many other cultures. It seems that the existence of a deity is something that every culture comes to accept at some time or another. In "Would Tarzan Believe in God?", the authors say that, "...many cognitive scientists see the universality and pervasiveness of religious belief as suggesting that it is a natural feature of evolved human psychology." (Banjeree, pg. 1) There are none who would

Mount St. Helens Location: Washington, United States Latitude: 46.20 N Longitude: 122.18 W height: 2,549 meters or 8,364 feet - 9,677 feet before May 18, 1980 Type: Stratovolcano Number of eruptions in past 200 years: 2-3 Latest Eruptions: Between 1660-1700, around 1800-1802, 1831, 1835, 1842-1844, 1847-1854, 1857, 1980-? Present thermal activity: strong steaming Nickname: Mount Fuji of the West Remarks: continuous intermittent activity since 1980 with occasional eruptions of steam and ash; occasional pyroclastic flows; intermittent dome forming. MSH is considered a young volcano that developed over the last 40,000 years and is one of the most active volcanoes in the Cascade Range. Geologists predicted that the

Before May 1980, Mount St. Helen in Washington State ha been quiet for over a hundred years. It had been calling "the Fuji of America " because it's symmetrical cone resembled the famous volcano in Japan. It's massive eruption on Sunday, May 20, 980, changed that shape. Mount St. Helens lost 3.7 billion cubic yards of rock. Volcanic ash was send fifteen miles into the air, and very hot winds blew in all directions. Two hundred thirty square miles of forest were flatten. Seventy percent of the snow and ice on the mountain melted, causing an enormous landslide of mud, volcanic ash, rocks, and trees to speeding down the mountain at 500 miles per hour. In the eruption, fifty-seven people lost their lives, some as far away as thirteen miles from the mountain. Most of them were scientists, loggers, and journalists.

Figure 1: Mount St. Helens location activity in 1980 were observed in the middle of March when earthquakes were detected beneath the volcano. There were many quakes each day and the largest ones were felt by people in the nearby area. At 8:32 am PDT on May 18, 1980, Mount St. Helens erupted following a magnitude 5.1 earthquake that began about 1.5 km below the volcano (Tilling, Topinka, & Swanson, 1984). This was the most devastating event in the two months of activity. The top 400 m of the mountain were blown away, 500 km2 of the Gifford Pinchot National Forest was covered with grey ash and 57 lives were lost (Zeilinga de Boer & Sanders, 2002).

However, Mt. Saint Helens was the smallest (at 3000 meters before eruption) and youngest of the range (Mount St. Helens Eruption: Facts & Information, livescience.com). With what we have learned in this course and in the book, this is consistent with what we know about mountain formation and volcanic activity. Thus, this would make sense that Mt. Saint Helens had been brewing beneath its surface, becoming closer and closer to eruption with magma levels within the mountain raising at up to more than 1.5 meters per day, (Mount St. Helens Erupts, history.com). The mountain is known to have erupted several times in the past, particularly in the early and mid
