Volcanoes

Compare!

On your seismogram: ● Label the S waves, P waves, and Surface waves ● Find the SP interval ● Find the amplitude of the S wave

Quake Damages ● Destruction of buildings and roads ● widespread fires ● liquefaction and landslides ○ (sediments are filled with water and begin to act like liquids) ● Tsunamis

How a volcano erupts is based on viscosity. What is viscosity? • Viscosity is how resistant a substance is to flowing. For example, honey is more viscous than water.

• Magma that is very viscous will explode, magma that is less viscous will flow. • Lava that is hotter will be less viscous (like if you heat up honey) and will flow more. • Lava contains dissolved gases, and if the lava is very viscous, those bubbles cannot expand. Instead, the bubbles will explode upwards.

Volcanoes also eject pyroclastic materials (Particles)

Geohazards

“A major 7. 0 magnitude earthquake struck southern Haiti in Jan 2010, knocking down buildings and power lines and inflicting a catastrophe for the Western Hemisphere's poorest nation. ” …However, a 7. 0 magnitude has also hit California without causing as much damage. → Why do you think Haiti had more damage even though the earthquake was the same intensity?

What is a Geohazard? Geo= earth Hazard= Disaster Geohazard= Natural Disaster on Earth

What type of destruction occurs from geohazards?

Wealth of Nations • • • San Francisco, CA = $46, 381 Haiti $733 Mexico = $8, 144 Chile = $9, 200 El Salvador = $3, 100 Kobe, Japan = $39, 731 (expressed as GDP, Gross Domestic Product, or the average wealth per individual)

Group Activity! How can we prevent destruction from geohazards?

After researching your Earth Science textbook and internet resources from the US Geological Survey and NC Department of Natural Resources on Geophysical Hazards (volcanoes, earthquakes, landslides, and tsunami), create a public safety announcement that describes the history of the geohazard and ways to protect the area from that specific geohazard. Support your announcement with evidence from your research. Give examples from past or current events or issues to illustrate and clarify your geohazard. Include preventative methods (how to construct buildings and homes) and precautions for people who live in those areas.

Exit Ticket If you had to choose somewhere to live that had the fewest geohazards where would you live and why? Either use an actual location or describe one.
