Hazards
Gas
- Sulfur Dioxide gas creates air pollution that irritates skin, nose, throat, and eyes
- Carbon Dioxide is so concentrated that it kills animals and humans
- Acid rain that some times takes the form of Hydrochloric acid

Lahars
- hot or cold mixture of water and rock fragments, often resembles a flow of concrete
- hundreds of meters wide, tens of meters deep
- flows at several tens of meters a second (too fast to outrun)

Landslides
- large rocks or debris falling rapidly downhill
- if the landslide contains enough water it will transform into a Lahar

Lava flows
- lava thats errupted during non explosive periods
- can travel up to 10 km / hour
- can result in lahars

Pyroclastic Flows
- high density mixtures of hot, dry rock fragments and hot gases that move at high speeds
- can result from non explosive or explosive periods of the volcano's history
- can result in lahars

Tephra
- gas clouds that are carried several hundreds of kilometers from the vent
- can disrupt machinery and lives very far away from the volcanoe

  • A Look Into Volcanoes
    A Look Into Volcanoes I. Introduction Volcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth\'s surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world\'s volcanoes lie beneath the sea, f

    Lazzaro Spallanzani Lazzaro Spallanzani Lazzaro Spallanzai, was the Italian physiologist who was one of the founders of experimental biology. Born in Scandiano, a small town in the providence of Emilia on Jan. 12, 1729 , Spallanzani was among the many dedicated philosophersof the eighteeth century (Lazzaro...1). His main scientific interests were biological and was a master at mircoscopy,but he also looked into problems of physics,chemistry, geology, and meteorology, and volcanology (Gillispie,1

  • Mauna Loa
    Mauna Loa Mauna Loa: The Fiery Mountain Mauna Loa is Earth\'s largest volcano and most massive mountain as it takes up nearly half of the flourishing landscape of the island of Hawai\'i. This island is actually made up of five volcanoes, Kohala, Mauna Kea, Hualalai, Mauna Loa, and Kilauea, all in such close proximity that they fused together to form one whole island. Mauna Loa is located in the south central area of Hawai\'i, in the Hawai\'i Volcanoes National Park and its coordinates are 19°5\
