25. Statistical analysis of the runout distance of pyroclastic density currents and implications for emplacement mechanisms

Pyroclastic density currents (PDCs) are hot mixtures of gas and particles generated by volcanic eruptions. They propagate on the ground at high velocity and can travel distances that are commonly of several tens of kilometers. Understanding the factors that control the long runout distance of PDCs is important for hazard assessment. In this context, we collected data on PDCs in more than 200...

24. Data-Driven Framework for Uncovering Hidden Control Strategies in Evolutionary Analysis

Nourddine Azzaoui (Laboratoire de Mathématique Blaise Pascal - UCA)

10/25/23, 3:00 PM

Natural risks are characterized primarily by their uncontrollability, or at least, their difficulty in being controlled. In this instance, the goal is to try to understand the mechanism that causes these hazards as well as the variables that affect the processes' evolutionary behavior. In this talk, we provide a data-driven approach for identifying an evolutionary system's hidden control...
