Moreover, this tool is designed for complementing long-term hazard assessment with continuous monitoring data when the volcano goes into unrest.
Journal of Volcanology and Geothermal Research 290, 111, 2015] who defined the principle for a new methodology for conducting short-term hazard assessment in unrest volcanoes.
Short-term hazard assessment is an important part of the volcanic management cycle, above all at the onset of an episode of volcanic agitation (unrest).
So far, the schemes for short-term hazard assessment have put only minor emphasis on evaluating phenomena associated to non-magmatic hazards, despite the fact that these have had significant economic and social impact in the past.
This long-term hazard assessment is a significant contribution that will enable local authorities to implement more rational territorial planning and to design better emergency plans for coping with future volcanic crises.
We used existing historical records of past eruptive activity, available geological knowledge and monitoring data gathered over the past sixteen years to conduct the first comprehensive, long-term hazard assessment of this volcano, aimed at helping to reduce the potential risk it poses.
Using the same case study, the eruption on Pinatubo (15 June 1991), this work introduces a new free Python tool, ST-HASSET, for implementing Sobradelo and Martí (2015) methodology in the time evolution of unrest indicators in the volcanic short-term hazard assessment.
Higher spatial resolution DEMs allow for a higher number of lavasheds to be detected (Fig. 5), making them valuable for short-term hazard assessments.
This strongly suggests a great potential to reduce the hazard at possible future sites of earthquakes relative to long-term seismic hazard assessment.
This indicates great potential to reduce the hazard at possible future sites of earthquakes relative to long-term seismic hazard assessment.
This work follows from Sobradelo and Martí [Short-term volcanic hazard assessment through Bayesian inference: retrospective application to the Pinatubo 1991 volcanic crisis.
