Can human curiosity affect dynamic risk?

Can human curiosity affect dynamic risk?

In simple words, the volcanic risk (R) can be defined as R = Value × Vulnerability × Hazard. The value is a figure that varies according to the total number of population and / or infrastructures at risk during a volcanic eruption, vulnerability is the percentage of value at risk for a given volcanic event and the hazard is the probability that a certain place may be affected by a determined hazar ...[Read More]
