Question
Earthquake
A had a magnitude of 6.4;
earthquake B had a magnitude of 7.4.
What can you say about the relative sizes
of these two events?
O B released the equivalent of 1 metric
kiloton of TNT more energy than A
O maximum wave amplitudes of B were
about 30 times greater than those of A at a
distance of 100 km
maximum wave amplitudes of B were
about 1 m higher than those of A at a
distance of 100 km
B released about 30 times as much energy
as A
B released about 10 times as much energy
as A

The process of liquefaction and related
damage is most likely during earthquakes
in which setting?
O only under tall buildings with narrow
foundation footprints
O near or above water-saturated sandy
sediments within the area of strong shaking
within the areas flooded by large tsunamis
O on steep slopes in rocky mountainous areas
where shaking is strong
over the long but relatively narrow zone
where a fault breaks the surface
