Answer:
Options (2), (3), (4), and (7)
Explanation:
The factors that affects the number of deaths and the amount of damage caused by an earthquake depends upon the following things-
(1) Magnitude- The magnitude of an earthquake controls the amount of damage and loss of people. A high magnitude earthquake can cause greater damage in comparison to a low magnitude earthquake.
(2) Distance- The distance also plays an important role. When the distance from an earthquake is short, then the places nearby, at a certain radius gets affected very badly. Whereas, the places that are at a far distance, are not affected much by the earthquake.
(3) Depth- The depth of an earthquake depicts the epicenter distance. Shallow depth earthquakes are responsible for massive destruction. But, the deep focus earthquakes does not affect much unless it has a much stronger magnitude.
(4) Material that is used for construction of buildings- The type of materials that is used for construction purpose also is important. Weaker materials are easily broken down resulting in the collapsing of building. So, hard and resistant rock must be selected in order to maintain the stability of the buildings.
Thus, the correct answers are options (2), (3), (4), and (7).
