Why did the 1988 armenian earthquake (in the armenian republic, then part of the former soviet union) result in an estimated 25,000 deaths?

the quake hit at rush hour; thousands of motorists were killed when freeways collapsed.

the buildings were constructed on unconsolidated, water-saturated, lakebeds and foundation failures were common.

numerous, poorly constructed, top heavy, concrete slab buildings collapsed.

the area was densely populated and right at the epicenter of a magnitude 8.5 quake.

The correct answer is C. Numerous, poorly constructed, top heavy, concrete slab buildings collapsed.

Explanation:

The 1988 Armenian earthquake occurred in the northern part of Armenia that belongs to a seismic belt. This earthquake had a magnitude of 6.8 and lasted only about 20 seconds, despite this the Earthquake was devastating to the zone as many buildings collapsed as this lead to more than 25,000 deaths. This occurred because during this period most of the buildings were poorly constructed as the structures were not stable or follow basic construction principles and they included heavy materials such as concrete or slab, due to this, once the earthquake hit them they collapsed. Thus, the reason the 1988 American earthquake result in around 25,000 deaths was "numerous, poorly constructed, top-heavy, concrete slab buildings collapsed".

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.
