Introduction to Earthquake Engineering

Fractures and faults were the actual mechanism of earthquakes and not its results.

• TRUE

• FALSE

The Elastic Rebound Theory proposed three major stages of Earth's crust movement. Who formulated this theory?

• Alfred Wegener

• Prof. B. Koto

• Harry Fielding Reid

• Robert Mallet

A rock mass above an inclined fault, called the hanging wall side, moves up with respect to the footwall side.

• Thrust Fault

• Normal Fault

• Sinistral Fault

• Dextral Fault

This phenomenon occurs when movement on a fault deep within the earth breaks through the surface.

• Surface Rupture

• Earthquake Rupture

• Fault Line

• Plate Boundary

"The lithosphere, consists of several large and fairly stable solid rocks, is moving horizontally relative to neighboring rocks."

• Ring of Fire Theory

• Elastic Rebound Theory

• Theory of Continental Drift

• Theory of Plate Tectonics

A type of plate boundary where plate edges scrape with each other.

• Covergent Plate

• Transform Fault

• Divergent Plate

• Oblique-Slip Fault

What do you call a seismic wave that moves the ground from side to side in a horizontal plane but at right angles to the direction of propagation.

• P-Waves

• S-Waves

• Love Waves

• Rayleigh Waves

S-Waves travel faster than P-Waves.

• TRUE

• FALSE

Compressional waves which exert a push-pull force. Its motion is the same as that of a sound wave.

• P-Waves

• S-Waves

• Love Waves

• Rayleigh Waves

What do you call the process of locating earthquakes based on the recorded seismic activity on three or more stations?
