Zusammenfassung

Pyroclastic flows - a hot mix of gas, volcanic ash and rock fragments that moves like a snow avalanche - are amongst the most destructive hazards caused by a volcanic eruption. They develop spontaneously, move fast, and their exact trajectory is hard to predict. The authors propose a strategy to comprehensively obtain parameters determining flow behaviour, which will provide crucial input for numerical flow simulations and hazard assessment for one of the deadliest volcanic threats. A crucial aspect is the use of unmanned aerial vehicles (drones) to safely obtain data in high-risk zones. They ...
