Earthquake and Fire Safety Quiz

What is the primary cause of ground shaking during an earthquake?

• Fault rupture due to heat energy

• Elastic energy released during faulting

• Chemical reactions in the Earth’s crust

• Volcanic eruptions

What theory explains how stress builds and releases energy during an earthquake?

• Seismic Wave Theory

• Plate Tectonic Theory

• Elastic Rebound Theory

• Liquefaction Theory

Which type of seismic wave causes the most damage?

• P-Waves

• S-Waves

• Surface Waves

• Rayleigh Waves

Which seismic wave moves side-to-side?

• P-Waves

• S-Waves

• Love Waves

• Surface Waves

What does NOT affect the intensity of ground shaking?

• Earthquake magnitude

• Depth of focus

• Distance from epicenter

• Type of fault movement

Why is horizontal shaking more destructive than vertical shaking?

• It travels faster through rock.

• It lasts longer.

• Buildings are less resistant to horizontal motion.

• It occurs only in larger earthquakes.

What is the definition of liquefaction?

• Ground shaking causing a fault to rupture

• Transformation of sediments into a liquid-like state

• Landslides caused by water saturation

• Cracks forming in solid ground

Which feature of liquefaction involves wave-like motion on flat ground?

• Flow Failure

• Lateral Spread

• Ground Oscillation

• Loss of Bearing Strength

Which type of landslide involves mud or earthflow caused by water saturation?

• Topples

• Rock Falls

• Flows

• Lateral Spread

Which factor does NOT contribute to earthquake-induced landslides?

• Groundwater pressure

• Heavy rainfall

• Presence of hard rock

• Erosion
