Such victims actually
accounted for 16% of the total number of deaths
(6). Other anecdotal
reports suggest the efficacy of moving to a protected area such as a
doorway or under a desk.
Clearly, the behavior of occupants during and immediately after an
earthquake has been inadequately studied (87,88).
From the 1985 Mexico City
earthquake, anecdotal reports of little islands of
concrete slab perched on the tops of children's school desks while
the rest of the ceiling had collapsed to the floor suggest that
earthquake drills might be worthwhile (89).
The real question, of course, is whether the children would
have been able to get under the desks in time to prevent injury if
the school had been occupied.
In the best documented study of occupant behavior during
earthquakes, the behavior of 118 employees of a county office
building in Imperial County, California, was studied after a
magnitude 6.5 earthquake damaged their building (90).
Of interest here is the finding that 30% of the desks under
which people in this building sought refuge moved away during the
shaking, thus exposing the person to possible injury from falling
objects. Following the 1989
Loma Prieta earthquake, Durkin et al. examined the value of taking
protective actions commonly suggested in citizen safety advisories
(e.g., standing in a doorway or crawling under a desk) (31,79).
They found that at least 60% of those injured during the
period of shaking were engaged in some form of protective action at
the time of their injury, but those injuries tended to be minor.
Durkin's results suggest that while commonly recommended
self-protective actions may enhance people's safety in total
building collapse situations, people who rush to protect themselves
in less hazardous settings may actually be increasing their risk of
minor injury.
