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).
Approximately 25 million years ago, all of Eastern Washington was flooded due to the eruption of the Columbia River Basalts. As the molten rock came to the surface, the Earth 's crust gradually sank into the space left by the rising lava. Explosions of magma filled the area and the coverage was extensive. The now Columbia River Plateau was filled with basalts and formed rivers through the areas of flow. Grande ronde and wanapum basalt was created by fissures about 17-15 million years ago and made up about 85% of the flow.
On May 18th, 1980, thirty-five years ago, Mt St. Helens erupted and changed the course of history. This towering Washington volcano is part of the Pacific Ring of Fire. During the eruption the mountain spewed hot gases, rocks and, ash into the sky causing a mud flow down the mountain 's sides. According to the National Oceanic and Atmospheric Administration," this was the deadliest and most economically destructive volcanic event in the history of the United States". It destroyed over 230 square miles of land.
The glaciers cover about 10 percent of the Earth it forms in the Canada, Greenland, and Antarctica (United States). There are giant ice sheets that cover most of the continent and the depth of the ice sheets range in different thickness ranging from hundreds of feet to thousands of feet. The glaciers have made an enormous impact on the Rocky Mountains by digging through the ground, depositing the sediment that it has picked up, and creating lakes. http://www.encyclopedia.com/topic/Rocky_Mountains.aspx Glacier erosion When glaciers scrapes across the ground moving dirt and creating deep valleys, it is a process called glacier erosion. It is believed that the glacial erosion has caused the Rocky Mountains to increase its height.
Mass Hysteria After an Earthquake Devina Gallegos SECTA Mass Hysteria After an Earthquake In 2010 a major earthquake of a high magnitude hit the country of Haiti. The earthquake hit near the town of Leogane not too far from Haiti’s capital. The earthquake was one of the highest ever recorded. It was catastrophic and put the country in ruins by destroying millions of homes, buildings, and roads. After the quake the country was going through a case of mass hysteria.
Imagine being outside in a gigantic thunderstorm with wind speeds up to 300 mph. Suddenly, violent, rotating columns of air extend from the sky, reaching all the way down to the ground. The funnel shaped twisters starts destroying large buildings and homes alike. They uproot trees, and vehicles race through the air for miles. These channels of intense wind are called tornados.
Often wildfires occur in uncultivated, unpopulated areas, however, they can occur anywhere and destroy homes, agriculture, humans, and animals in their path. When it comes to wildfires there are two main categories of immediate causes, natural occurring, and human. Natural occurring causes of wildfires could be link to volcanic eruption, heat waves, droughts, cyclical climate changes, etc. Among those natural occurrences lighting is at the very top of the list. The average 10-year total of U.S. wildfire acres burned and caused by humans is 1.9 million acres while 2.1 million acres burned are lightning caused annually (2005).
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 2004-2008 eruptions of St Helens, Washington, Unites states has been recorded
Decades ago, in an epic “Beowulf”, Beowulf has slain the fire dragon, the creature that terrorized all the people who lived nearby where the dragon lives. The winter in Sweden was not as bleak as it was in mid 17th century. The blizzard was as disastrous as could be. The dragon’s body was covered in pure white snow on the pinnacle of the highest mountain. Not even the slightest bit of ice were melted through the rough skin of the fire dragon.
An earthquake is a shaking of a part of the earth’s surface, often causing great damage. (merriam webster.com) Earthquakes kill approximately 8,000 people each year. An average earthquake only lasts about one minute. (Randomhistory.com) Earthquakes are important and relevant because of the lives they take and the damage they cause. On 1960, May 22 the strongest earthquake hit off the southern coast of Chile.
