What does earthquake engineering involve?
Designing structures to resist earthquake forces
In earthquake engineering, what is the main purpose of analyzing structures and the surrounding environment?
To determine the maximum stresses on structures
How does earthquake engineering contribute to protecting society?
By minimizing the seismic risk to acceptable levels
What is the significance of improving soils and stabilizing natural slopes in earthquake engineering?
To guarantee the stability of structures on weak soils or slopes
What is the primary objective of configuring and detailing structures in earthquake engineering?
To make structures resist seismic stresses and deformations
Which statement best describes seismology?
The study of seismic wave generation, propagation, and measurement
What is the role of the asthenosphere in plate tectonics?
It enables the motion of lithospheric plates
What was the approximate death toll due to earthquakes globally between 1998-2017?
750,000
How many earthquakes does PHIVOLCS record on average per day?
20
How many people were affected by earthquakes between 1998-2017?

What was the official total number of confirmed dead or missing individuals from the Japan Earthquake and Tsunami of 2011?
18,500
How do earthquake forces affect the structural analysis of buildings?
They increase the need for reinforcement
What type of particle motion is associated with Love waves?
Horizontal
Why are Love waves considered dispersive?
Because they can only propagate in a velocity layered medium
What is the relationship between Love wave velocity and wavelength?
Velocity of long wavelength Love waves is close to S-wave velocity in the half-space
How are Love waves generated according to Love (1911)?
By constructive interference of reflected SH-waves from top and bottom of a soil layer
In what direction do Love waves propagate?
Perpendicular to the particle motion
What happens when the angle of reflection at the base of a soil layer is less than the critical angle?
S-waves are trapped in the soil layer
