Volcanic risk can be defined as "the probability of harmful consequences or expected loss of lives, people injured, property, livelihoods, economic activity disrupted, or environment dammaged) resulting from the interaction between a volcanic hazard and vulnerable conditions.
(adapted from an ISDR definition in: Living with risk).
Mount Pelee can display a wide range of volcanic hazards. Fortunately, volcanologists have studied and mapped those threats...
Tephra and balistic ejecta
Landslides and debris avalanches
Those hazards are a threat for the neighboring population and activities. Nowadays, about 22,000 people live directly on the slopes of mount Pelée, including the rebuilt town of St. Pierre.
Facing volcanic hazards, there is no parade. Only, a constant monitoring of the volcano (role of the volcano observatory) allows scientists to detect and predict the possibility of a future eruption. Land-use should also be adapted in order to lessen the consequences of the next eruption.
