Hi Chegg Team,
I need some help with few questions here.
Please note: only state the answer. Thank you.
Question 4
Why can the worse building damage from an earthquake occur in regions that are relatively far away from a quake's epicenter, rather than right at the epicenter?
Seismic waves can hop and skip all over the place.
The ground motion of an earthquake is never the strongest at its epicenter. That is due to wave refraction as the waves spread as they travel up from the focus of the earthquake.
The intensity of ground shaking near the epicenter is largely controlled by what type of ground material that is being shaken. Therefore, ground shaking can have uneven distribution around the epicenter, if the ground material is heterogenous, like granite in one place, and water-saturated, thick-layered, loose sands in another.
The statement is false. Strongest ground shaking is ALWAYS fround right at the epicenter in all earthquakes.
Earthquake epicenters always occur where the strongest-built buildings are found.

Explanation / Answer
Answer : d
The intensity of earthquake is usually greater near the epicenter so that is why most damage occurs in and around the epicenter region
