Extra Stuff Flashcards
What safety measures can be taken to mitigate earthquake hazards?
Building earthquake-resistant structures, creating tsunami warning systems, and educating the public on emergency procedures.
Why can’t S-waves travel through the Earth’s outer core?
Because S-waves are shear waves and cannot move through liquids, and the outer core is liquid.
Explain the difference between an earthquake’s magnitude and intensity.
Magnitude measures the energy released at the source, while intensity measures the effects on the Earth’s surface and structures.
What is the Ring of Fire and why is it significant?
A region around the Pacific Ocean with a high concentration of volcanoes and earthquake activity due to plate boundaries and hotspots.
What factors influence the VEI rating of a volcanic eruption?
Volume of ejecta, eruption column height, and qualitative descriptions of the eruption’s explosiveness.
How do subduction zones contribute to volcanic activity?
One plate sinks beneath another into the mantle, melting and forming magma that rises to create volcanoes.
