Definition of Hazard Zones
Defining hazard zones for the effects of quakes is more difficult
than for eruptions and most Small, non-damaging earthquakes will be felt more frequently by
people living on the slopes of these volcanoes. The effects of a
large quake under Kilauea or Mauna Loa, however, will not One problem in assigning seismic hazard zones to the island is
that the ground shaking during a strong quake may vary within a
small area. This variation is because the effects of quakes are
closely related to the nature of the underlying ground; for example,
whether it is mainly lava bedrock or soil. Two homes in the same
neighborhood may suffer different degrees of damage depending on
the properties of the ground upon which they are built. In addition,
local The risk from living in a seismically active area, unlike that of living in an area prone to being covered by lava, also depends to a large degree on the type of construction used in a given home. Quake shaking may damage certain types of houses, while leaving other types of construction unscathed. For all these reasons, earthquake hazards are highly localized, and it is difficult to define broad zones with the same relative degree of hazard.
