Resumo(s)
S. Miguel is constituted by several volcanic structures,
considering this island, in spite of its current quiescence,
one of the most eruptive poles of the Atlantic. This is the
fundamental characteristic from which other hazards,
such as CO2 emission from fumaroles, volcanic and
tectonic earthquakes as well as mass movements associated
with both episodes of intense precipitation and
seismic activity, were developed. An exploratory study
was developed to evaluate the coexistence of populations
with the stated risks. Using a methodology of measurement,
the application of a survey to a population sample,
it is verified the low perception of the volcanic risk, both
by the populations and by the institutions and authorities
in the communication of the risk. However, it is noted
that the population surveyed seeming to underestimate
this threat, as if the memory of previous eruptions
constituted only a historical heritage and, at the same
time, they have a high/average perception of the other
risks associated, namely seismic and hydrological risks
(this includes the consequences of intense precipitation,
that is, mass movements). Also, it was noted that this
survey relies differently on the authorities and institutions
responsible for risk communication and risk management.
