Therefore, the management of volcanic disasters requires fast and accurate information on the behaviour and evolution of the fows, mainly related to their extension, displacement, and trajectory. This was the case during the disaster linked to the volcanic event that occurred on the island of La Palma in the Cumbre Vieja area at the end of 2021, which lasted eighty-five days. This paper describes part of the work performed by many diferent groups to provide predictive information aimed at feeding the early warning system set up during the disaster. This case shows the experience in the use of a probabilistic simulation algorithm implemented in the Q-LavHA plugin for the QGIS software, which is both easily accessible and applicable, to analyze its features in detail, as well as its predictive capacity. The results show that the model can eficiently and quickly satisfy the demand for this type of information, and its high similarity value is also validated by the Kappa index.<br>Keywords: Lava fow simulation \u00b7 Volcanic hazards \u00b7 Disaster risk reduction \u00b7 Early warning \u00b7 La Palma<br><\/p>\n\n\n\n<p><strong>the authors<\/strong><\/p>\n\n\n\n\n\n<ul class=\"wp-block-list\">\n<li>Nerea Mart\u00edn-Raya nmartir@ull.edu.es<br>Jaime D\u00edaz-Pacheco jdiazpac@ull.edu.es<br>Abel L\u00f3pez-D\u00edez alopezd@ull.edu.es<br>Pedro Dorta Antequera pdorta@ull.edu.es<br>1 Land Planning and Risks Research Group (GEORIESGOS), Chair On Disaster Risk Reduction and Resilient Cities, University of La Laguna (ULL), San Crist\u00f3bal de La Laguna, Tenerife, Spain<br>2 Infrastructure Services of the Island Council of La Palma (Canary Islands), Santa Cruz de La Palma, Spain<\/li>\n<\/ul>\n\n\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>art\u00edculo de Antonella Pino d&#8217;Astore Entrevistamos a Nerea Mart\u00edn Raya, investigadora predoctoral Universidad de La Laguna.
