about eight times. Katmai National Park and Preserve is located on the northern tip of the Alaskan Peninsula and is made up of six active volcanoes and the surrounding forests, lakes, and mountains. Maybe the most well known of the volcanoes are Novarupta and Mount Katmai, famous for their eruption in 1912. Katmai National Park is located in the southern part of Alaska. It was established on September 24th, 1918 to protect the recently devastated region. President Woodrow Wilson signed the bill, entering
later known, as Novarupta, literally translated as “new eruption”, is located in Katmai National Park and Reserve on the Alaskan Aleutian Range (Pidwirny and Jones 2009). Novarupta’s eruption caused immediate impacts to the native Alaskan climate as well as impacts to earth’s global climate overall. Volcanoes can leave enormous impacts locally to geography and ecosystems, but because of Novarupta’s status as the strongest volcanic eruption in Alaska’s recorded history, Novarupta left local as well
eruptions include hot pyroclastic flows and surges, mudflows, debris avalanches, landslides, floods, and ash fallout. The author also says that they are many more hazards, including typical eruptions, large caldera-forming eruptions similar to the 1912 Novarupta event, though rare, have occurred at about a third of the volcanic centers in the region. The Aniakchak caldera-forming eruption 3,400 year BP caused the collapse of a large volcanic cone, formed a crater 10 kilometers in diameter,
Volcanoes are formed when magma is expelled from the Earth’s surface, resulting in volcanic eruptions consisting of ash and lava. Over time, the lava cools and forms into rock on the Earth’s surface. Whenever an eruption occurs, the newly-formed rock from the lava layers continuously until the volcano takes its shape. Volcanic eruptions have taken place for thousands of years, and even today, according to the U.S Geological Survey (2010), there are approximately 1500 active volcanoes located throughout
1. Despite being in a dangerous location, the slopes of volcanoes can be attractive to people setting up homes due to the rich, fertile soil 2. According to scientists, in the last 500 years approximately 20,000 people have died as a result of volcanic eruptions 3. A volcano is landform (generally a mountain) where, during an eruption, ash, gas and molten rock (magma) escape through the Earths surface 4. Approximately 1 in 10 people in the world live within danger range of an active volcano
