The equation that Booth used to calculate risk includes probability of occurrence, indicating that eruption frequency has been examined; however, neither the probability used nor the description of prior eruptive history are provided in the publication. Tephra Falls and Ballistic Projectiles TEPHRA FALLS TEPHRA FALLS TEPHRA FALLS - refers to volcanic rock and lava materials that are ejected into the air by explosions or carried upward by the eruption column's hot gases or lava fountains. village occupied by 1700 people. In this scenario volcanic alert levels and bulletins may not be released prior to eruption. It can also trigger lahars directly by melting icecaps and snow.

Generally, the distance travelled and the total area impacted by ballistics increases with increasing explosivity, i.e. This can occur when end-users do not comprehend or are unaware of the science being presented, the information is not what is actually needed by end-users, the science is communicated poorly to end-users, or there is a lack of trust between groups (Haynes et al.
