Only a very large eruption will affect this area. Making a judgement to enter these zones is a personal choice. Beware of the mesmerising effect of a volcano. Like watching the waves crash on to the shore you can be lulled into a hypnotic state of false security. Don t stay too long.
Volcanic activity can change without warning.
23 Volcanologists were killed on volcanoes. What the volcano has done in the past is what it is capable of doing in the future. Eruption styles are very predictable on a particular volcano. Record the number of explosions per hour and know what the volcano is doing. Do not expect other people to come into the danger zone and rescue you.
