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?
(a)
Select the odd one.
Rossi-Forel Scale
Mercalli Scale
Medvedev-Sponheuer-Karnik Scale
Richter Scale
What is the maximum magnitude of an earthquake ever recorded in history?
(a)
The PHIVOLCS Earthquake Intensity Scale was developed based on the Rossi-Forel Scale. What is the maximum possible intensity in PEIS?
(a)
In the Moment Magnitude Scale, if the measured amplitude of a 2.0 Mw earthquake is 20 mm, what could possibly be the amplitude of a 3.0 Mw earthquake?
200 mm
2,000 mm
640 mm
