Hawaiian Volcano Hazards Exercise Yo u are a Hawai Volcano Observatory (HVO) scientist in charge of assessing the natural hazards associated wi Kilauea's activity - especially the dangers to people and property in the region There are three parts to this exercise: Background, the HVO Kilauea hazard assessment, and writing a short news release. There Kil are 3 topographic maps and 1 geologic map to use to assess the natural hazards associated with auea's activity including the dangers to people and properties in the region. Part of the object of this exercise is to learn more about maps In part based on Brian Scheidt, Mineral Area College, Kim West, University of Saskatchewan, Lyn Gualtier, Seattle University Background View the eruption movie: https://www.youtube.com/watch?v-GTMg01IAkFo . What type of material is being erupted? (pyroclastic eruption or lava flow and its type). Does this material have a high or low viscosity? If you were walking across the surface of the lava flow after it cooled, what type of lava would you be walking on: a) Aa b) Pahoehoe c) Ash fall d) Volcanic bombs In general, what is the general chemical composition of this material (mafic, felsic, or..).? What is the name of the resulting rock? Based on the previous questions, and what you know about Hawaiian volcanoes, what type of volcano are we look- ing at? What are the main gases emitted from a volcano? What are some potential hazards to someone living and crops being grown in the vicinity of this eruption? Consider the questions above
Explanation / Answer
The type of volcano in the video is shield volcano. This has a low slope with massive coverage of area, looking like a shield placed upside down. The volcano in the video is the Kilauea volcano which is active. These type of volcanoes erupt lava frequently. Particularly this volcano has low viscous lava. The gases that volcano erupt are Carbon di-oxide Sulphur di-oxide Carbon monoxide Hydrogen sulphide Water vapour Potential hazards to the settlements nearby these kinds of volcanoes: Gases emitted by the volcanoes causes breathing problems. Damage to the buildings by affecting the foundation by deformation of the ground. Due to the force of eruption lanslides may occur.
