GIS-based volcanic hazards, vulnerability and risks assessment of the Guallatiri Volcano, Arica y Parinacota Region, Chile
María-Paz Reyes-Hardy,Felipe Aguilera Barraza,José Pablo Sepúlveda Birke,José Pablo Sepúlveda Birke,Alfredo Esquivel Cáceres,Manuel Inostroza Pizarro +5 more
TL;DR: In this paper, the authors presented the first GIS-based volcanic hazard, vulnerability and risk assessment of Guallatiri volcano, based on the study of five key volcanic phenomena observed during Holocene eruptions, namely tephra transport, dispersal and deposition, flooding by lahars, lava flows, pyroclastic density currents, and ballistic projectiles.

Temporal evolution of roof collapse from tephra fallout during the 2021-Tajogaite eruption (La Palma, Spain)
María-Paz Reyes-Hardy,Sébastien Biass,Lucia Dominguez,Luigia Sara Di Maio,Corine Frischknecht,Costanza Bonadonna,Nemesio Pérez +6 more
TL;DR: The 2021 Tajogaite eruption produced a wide tephra blanket over 85 days of activity. Roof collapse due to static loads from tephra fallout was widespread, impacting 1.3% of the surveyed buildings. Clean-up operations were effective in mitigating roof collapse, reducing the number of collapses from 11% to 1.3%.

A GIS-based multi-hazard assessment at the San Pedro volcano, Central Andes, northern Chile
TL;DR: In this article , the authors present a multi-hazard assessment of the San Pedro volcano, a high-threat volcano from northern Chile, that produced two large-size Plinian eruptions (VEI 5 and 6) in the last 16 ka, and ten Strombolian eruptions between 1870 and 2021 CE, with the latest occurring on 2 December 1960 CE.
The spatiotemporal evolution of compound impacts from lava flow and tephra fallout on buildings: lessons from the 2021 Tajogaite eruption (La Palma, Spain)
Sébastien Biass,María-Paz Reyes-Hardy,Christopher Gregg,Luigia Sara Di Maio,Lucia Dominguez,Corine Frischknecht,Costanza Bonadonna,Nemesio Perez +7 more
TL;DR: This study assesses the compound impacts of lava flow and tephra fallout on buildings during the 2021 Tajogaite eruption, highlighting interactions between clean-up operations, rainfall, and lava flow dynamics, and providing insights for risk mitigation strategies in urban environments.
