For my unit review post I decided to go through and describe why all the volcanic hazards are hazardous:
Pyroclasitc Flows- These are hazardous because it is all the ash and rock that exploded from the volcano in a land slide down the side traveling at speeds up to 700 mph and temperatures up to 1830 degrees Fahrenheit. They would be impossible to outrun and would incinerate you on contact.
Ash Cloud- An ash could appears after a volcano has erupted. After the volcano erupts a cloud of ash pours out and covers the sky. These are hazardous because it suffocates you if you breathe in the ash and it also can make it very cold since it covers up the sun.
Tephra- Tephra is the rock that is thrown from the volcano when it erupts and it is hazardous because it could hit you and possibly kill you.
Fires- When a volcano erupts magma usually erupts from it and lava flows down the side of the volcano. If this lava comes into contact with anything flamable, it will start a fire and possibly burn down cities.
Lahars- lahars are mud flows that come after the volcano because a side of the mountain collapses after it erupts. This is hazardous because they can crush buildings and such.
Lava- Lava is the magma of the volcano when it reaches the surfaces and explodes out of the volcano. This is hazardous because when it comes out it is at extremely high temperatures and depending on the viscosity it can travel fast potentially starting fires.
Volcanic Gases- Volcanic gases are the gases that escape from the volcano when it erupts. Depending on which gases they are they can either lower or raise the atmospheric temperature and this can be hazardous.
Water Pollution- Water pollution happens because when the volcano explodes ash rains down onto the land surrounding the volcano. If this ash falls into a water source it will pollute the water and then the people won’t have any fresh water to drink from.
Landslides- Landslides occur because when the volcano erupts material spills out sometimes creating a landslide if the volcano was a mountain. This could be dangerous because landslides could crush everything in their path and they are also very fast.
Disease- Diseases can occur from volcanoes because of lack of nutrition of clean water and also because when people breathe in the ash from the volcano it clogs up their lungs ultimately making them suffocate.
Tsunamis- Tsunamis can be caused by a volcano because when a volcano erupts it can cause earthquakes which can cause tsunamis or it can cause large masses of land to fall into a body of water which can also trigger a tsunami.
