Question

See Hint The 2010 Mw 7.0 earthquake in Haiti caused an estimated 280,000 structures to collapse or sustain severe damage and resulted in the deaths of 100,000 to 160,000 people. However, a much larger Mw 8.8 earthquake in Chile that same year caused an estimated 550 deaths and significantly less damage to structures. Much of this difference in death toll and damage was due to the fact that Chile has strict building requirements, whereas no national building code exists in Haiti. What else can affect the number of deaths or amount of damage caused by an earthquake? Choose one or more: local weather patterns type of material on which structures are built distance from the earthquake depth of the earthquake education of populace locations of water wells magnitude of the earthquake

Answer 1

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).
