I don't know if this is really as obvious as you suggest. If you grow up near a volcano (see for example modern day active volcanoes in Indonesia or Etna and Stromboli in Italy), you will be used to some degree of rumbling and smoke and ashes spewing. So this might be regarded as a normal occurrence. Until it's too late, of course.
