And Ms. Bornas emphasized that it is the type of volcano that shows warning signs.
The reliability of issuance of VALs depends on the type of volcano, size of the eruption and monitoring network.
We discuss how well VALs have reflected the state of the volcanoes, and two factors that may influence these results -- the physical nature of the system, e.g. the size of the eruption or the type of volcano, the level of monitoring, or the number of outcomes (eruptions) from given volcano, and roles of population and scientific decision-making process.
Only in the Rift Valley was there the unique coincidence of this rather rare type of volcano and an evolving large-brained primate population.
-From what type of volcano is this kind of eruption most likely to occur?
Using all available resources, each group answers the following questions (written on the board for easier student access): –What type of volcano produced this eruption?
–What type of volcano is it?
Then, for each type of volcano, create a small "how it works" diagram.
This implies that, beyond the current classification, the non-magmatic unrest branch in the event tree could become the base for future probabilistic hazard assessment at any type of volcano, regardless of its state of unrest.
We investigate how the issuance of VALs varies with the volcanic system (size and type of volcano) as well as with some technical (e.g. monitoring network) and social (e.g. population at risk) factors.
