Pompeii Earthquake

Rocks are heated underneath the crust then pushed out through a volcano or the oceanic plate. The rock substance that becomes the crust will deposit back underneath the crust. All of the process can be credited to the dynamic nature of Earth.

2004-2008 St Helens Eruptions Ananth Kumaralingam Introduction Mount St. Helens is an active stratovolcano found in Skamania County, Washington, in the Pacific Northwest region of the United States. It is 154km south of Seattle, Washington and 80km northeast of Portland, Oregon. Mount St Helens is named after the British Diplomat and acquaintance of George Vancouver, Lord St Helens. Vancouver named the Area after his acquaintance after surveying the area in the late 18th century. The volcano is found in the Cascade Range and is part of the cascade volcanic arc, the particular region of volcanoes is known for its extravagant ash explosions and pyroclastic flows.

The story of Vasquez Rock Natural Park located in Agua Dulce, California began in 1874 when Tiburcio Vasquez a Californian bandit used the rocks to escape being capture by law enforcements. Due to the impact that Tiburcio created in the nearby communities the park was name after him. By 1970 the Los Angeles County Government acquired the rights to the park, but it was not until 1972 that the park was added to the National Registry of Historic Places. At the begging of its creation the park was populated by its first habitants the Tataviam Indians until the intrusion of the Spaniards. The Spaniards ruled the park and ruled the Indians until their death.

Mauna Loa has 2 trails to get to the top, which is Ancient times (First Ascent) and Ainapo (Easiest Route). The last time it erupted was in 1984. Mauna Loa is a shield volcano which traditionally it doesn’t produce a lot of violent eruption. It began by a slow 3-year period of a slow increase of an earthquake beneath the volcano. It started on March 25, 1984 between 1:25 and

The volcano slowly makes its way up to sea level and the submarine phase ends when it is shallowly submerged. The explosive phase begins when the volcano breaches the surface. Upon contact to air, a large amount of steam is produced and the lava becomes volcanic ash. Following the explosive phase is the subaerial stage which primarily consists of the “shield” shape forming and landslides. Following the shield stage is the post shield stage.

The quick drop in pressure causes the water in the geyser to become steam. According to Atteberry, the steam “expands to 1,500 times the volume of water and this expansion pushes water and steam from the mouth of the geyser in an eruption”. The eruption can last as long as the water in the geyser

Following up the information about the formation and deadliness of volcanoes is an example of a volcano, Mt.Tambora, one of the deadliest volcanoes ever. This volcano erupted over 200 years ago, but made a big impact all around the world. It erupted for three months in total. You could hear the explosions from over 1,000 miles away(Lassieur 4). This covered things in lava and was very hard to recover because the lava cools and hardens turning it into something as hard as bedrock(Lassieur 3).

Many science organizations have agreed that the probability of another super eruption is a low probability chances are quite slim with estimates being a minimum of 1 in 730,000. Technology has gotten better and scientists are better able to detect a possible eruption before it happens due to the many warnings that would appear. There are some warnings before volcanic eruptions occur such as multiple minor earthquakes, land uplift, gas releases through the many small holes which help relieve pressure. In an article by the NSF which stands for National Science Foundation scientists believe that another eruption wouldn’t occur for another 1-2 million years because based on research of its caldera cluster the volcano is undergoing its dying cycle rather than its ramping up cycle. The foundation states that “by studying the pattern behavior of the cycles and its previous eruptions by examining the rock minerals in the vicinity they’re given better clues to suggest the volcano is on its calm stage”.

There are many natural disasters that affect the world, for example, volcanoes. Mount St. Helens is known to be the most active volcano in the Cascade Range in Washington; effecting the people and the state. It was first recognized as a volcano in 1835! Before the eruption on May 18,1980, Mount St. Helens was a beautiful symmetrical cone, 3,000 meters above sea level. For most of the 20th century, many people viewed this mountain and recreation area as a beautiful and peaceful place, but after the volcano erupted in 1980 that view point was shattered.

The central idea of “Mount Vesuvius: Day of Disaster” is about the destruction Mount Vesuvius left on the city of Pompeii in 79 A.D. and the challenges the citizens who lived there faced. The article details that Mount Vesuvius erupted without warning to the townspeople. Although, there were signs of an eruption people didn’t have the advancement to understand them. People ran from their homes to escape the poisonous gasses floating in the air and ran for their lives as the pumice chased behind them. The fortunate ones who made it out were left with nothing but the clothes on their back, while the not so lucky ones were buried alive under the incinerating lava.

On January 12, 2010 a 7.0 earthquake hit the coast of Haiti along the capital of Port of Prince leaving the country in devastation and ruin, along with over 200,000 deaths. The country, already poverty ridden, faced many obstacles including families needing to provide the essential elements of food, water, and housing. Haiti, already known to be a poor nation, struggled further with economic issues along with the basic necessities of life. Haiti is known for its rich, wonderful coffee that is grown in the mountains and known to be its finest export. It has typically been sold or smuggled to the Dominican Republic, but with the devastation of the earthquake, Haiti is unable to export its product to other areas.

Triggered the largest landslide in recorded history and a major volcanic eruption that scattered ashes across a dozen states. The blast removed 1,300 feet off the top of Mt. St. Helen, making shockwave flow across the land, flattening forests and melting snow and ice, making it all muddy everywhere. A 57 total

Emily Axelsen: I do not think it is terrible. I find it fascinating that we can now learn so much about life in Pompeii! For me, examining the bodies that died at Pompeii means that we can learn about the lives of those who died so they will never be forgotten. For example, I was recently reading an article where Sarah Griffiths explained that we can learn more about the hairstyles and clothes of people who lived in Pompeii by exploring the bodies. Katherine: is that all you are concerned about? learning more about

Since the Mt. Vesuvius erupted in Pompeii many people died. Mt. Vesuvius erupted in Pompeii. Pompeii was destroyed then kept in a time capsule. Allisons findings may also carry over to other Baman towns. Pompeii is one of the most famous archaeological sites.

How would an eruption affect you? Physical A pyroclastic flow would destroy nearly everything in its path because of the hot gas and rock. When Aerial Volcano erupts, the pyroclastic flow and lava would burn through the surrounding areas
