Final answer:
The intensity and amplitude of earthquake waves decrease as they move away from the epicenter, resulting in less damage farther from the source, but interference patterns and geological factors can sometimes cause unexpected damage patterns.
Step-by-step explanation:
As the earthquake waves move farther from the epicenter, the magnitude of their effects decreases. This is due to the intensity of the waves, which is the power per unit area, becoming less as the waves spread out over a greater area. Intensity of seismic waves is analogous to sound waves emanating from a speaker; they dissipate over distance, explaining why the loudest sound is always near the speaker, similar to the most damage occurring at the epicenter.
The amplitude of earthquake waves, which is directly related to their energy, diminishes as the waves travel away from the epicenter. Thus, the potential for damage decreases with distance, producing less seismic impact farther away. However, due to seismic wave interference and varying local geological conditions, sometimes areas farther from the epicenter can experience significant effects while closer areas may be less affected.
