Answer to Question 2

An earthquake of magnitude 7.0 could inflict more death and destruction than a larger quake if (1) it occurred in a populated center rather than an unpopulated location; (2) it occurred along a megathrust fault that triggered a tsunami rather than any other kind of fault; (3) it triggered liquefaction, landslides, and subsidence of the substrate; (4) it occured in a poverty-stricken area with low-tech construction rather than seismically reinforced construction; or (5) it severed communication lines, gas lines, water mains, and so on and prevented assistance from being able to come to the aid of the area.
