Conclusion
Guillaume Lalubie
Some behaviours evolve while others remain constant:
- for the authorities, the precautionary principle was born on
Montagne Pelée, the 30 August 1902
- for the entire region, spontaneous evacuation starts when the first
ash falls
Eruptive impacts on the scale of the Lesser Antilles
- Area destroyed by volcanic activity constitutes a small surface of volcanic islands
over 360 years

- Roseau (Dominica) and Basse-Terre (Guadeloupe) are the last two towns most exposed
to volcanic risk. They will probably suffer the same fate as Saint-Pierre (Martinique) in 1902
and Plymouth (Montserrat) in 1997
- Magmatic activity represents 14 % of all volcanic activity. The hydro-volcanogeomorphologic (HVG) system was sollicited for numerous historical volcanic activities

Conclusion
Guillaume Lalubie
In 1902, the traumatism caused by the destruction of Saint-Pierre and the 28,000 victims,
but also the fascination for the events from the crater, contributed towards the magmatic
threats eclipsing some of other hazards (flashfloods, hydro-volcano-geomorphologic
phenomena, tsunami, etc.).
We consider that, with respect to volcanoes, the hydro-volcanogeomorphologic (HVG) threat is most significant because it is frequent,
spontaneous and cannot always be predicted, during and between
eruptions
To identify 3 types of torrents
in the Lesser Antilles
- Major volcanic torrent
- Secondary volcanic torrent
- Non-volcanic torrent
Most hydro-volcanogeomorphologic (HVG) hazards
occur in major volcanic torrents.
It is important to identify the
most threatening torrents.
The perception of natural hazards in the Lesser
Antilles by the Amerindian Kalinago

Introduction
All regional hazards are considered,
except for the volcanic hazards
(Breton, 1665).
The Kalinago vocabulary describes
the different intensities of torrential
flows.

Discussion
Conclusion
Guillaume Lalubie
Volcanic risk was not a concern when
compared to hydrological phenomena.
The Kalinago society probably
perceived volcanoes on a different time
scale than ours: a time scale suited to
the hazard impacts, their threats.

Is the volcanic risk in the Caribbean
overestimated ?
Certainly not, if we consider the areas
exposed to volcanic activity (Lindsay et al.,
2005)
Spatialisation
Discussion
Conclusion
Guillaume Lalubie
In the Lesser Antilles, the volcanic risk is
very well monitored by 3 volcano
observatories and the Seismic Research
Unit, University of West Indies (Trinidad)
However, in the context of an increasing demography, the
hydro-volcano-geomorphology problematic will be considered
more attentively, especially since it concerns flat surfaces with
rich soils, which are favourable to human settlements
