Sustainability, Journal Year: 2024, Volume and Issue: 16(8), P. 3133 - 3133

Published: April 9, 2024

This paper analyzes the spatiotemporal evolution of a complex landslide risk scenario in Latin American megacity, underscoring key challenges it poses for sustainable urban planning such cities. research draws upon multiple studies commissioned by mayor’s office megacity Bogota, Colombia, and utilizes aerial photographs satellite imagery from diverse sensor types. The methodology used considered six analysis scenarios: rural/natural, mining, urban, risk, stabilization environmental park, informal reoccupation. findings reveal interplay between megacity’s peripheral areas, which face constraints human settlement, their potential construction material exploitation. relationship was further compounded weaknesses controlling occupations, coupled with burgeoning demand developable land context (landslide area: 73 ha). scenarios highlighted predominant use reactive approach that addressed events, changes, or problems after they had occurred, rather than proactively anticipating preventing risks at study site. detected land-use transformations unveiled different historical moments, culminating disaster (804 houses destroyed, 3000 families risk). catastrophe necessitated radical significant intervention, incurring substantial costs administration (USD 26.05 million). largest recorded one most extensive areas across America.

The impact of collaboration on the community resilience program for residents Lumajang Regency varies. For variable “Strengthening local knowledge”, is preferable since it allows different communities to cooperate in gathering information from perspectives. According our research, if knowledge not strengthened through collaboration, will actually have reverse effect—that is, an catastrophe risk reduction. This due community’s still limited and underutilized participation government programs monitoring communicating response. Different findings were made network relationship variables, where influence relationships within disaster reduction non-significant, whether directly or indirectly cooperative mediation.

The Andean Southern Volcanic Zone: a review on the legacy of the latest volcanic eruptions

Andean geology, Journal Year: 2024, Volume and Issue: 51(2), P. 379 - 379

The Andean Southern Volcanic Zone (SVZ) concentrates many of the most active volcanoes continental arc, as well region’s recent and impactful volcanic eruptions. In this contribution, we briefly revise general characteristics SVZ volcanism provide a synthesis scientific findings related to latest eruptions (430 peer-reviewed publications with over 9,000 citations, large-magnitude (VEI 4-5) being studied. Our study shows that research has been primarily focused on environmental atmospheric impacts (29%), eruption descriptions physical volcanology (20%), hazard risk assessments (15%), other investigations complementary volcanology. Whereas least silicic (e.g., Llaima 2008-2009 Villarrica 2015) shed light magma replenishment degassing dynamics controlling styles, intermediate (andesitic-dacitic) offered clues either rapid or slow initiation, relevant phreatic-to-magmatic style transitions triggering mechanisms. On hand, (i.e., rhyolite-rhyodacite) provided unique observations ascent, high-rate extrusion, rheology, fragmentation processes, transitions. These have also inspired new generation tephrochronological, tephrostratigraphical, studies, aimed at assessing long-term (kyr-scale) evolution systems their associated hazards. We debate how knowledge gained from human coexistence are reducing in SVZ. Finally, discuss challenges opportunities emerging disciplines can complement our understanding region.

Al igual que en 1921-1922 y 1960, 2011-2012 se produjo una nueva erupción el complejo volcánico Puyehue-Cordón Caulle (CVPCC), con dramáticos impactos transfronterizos. El CVPCC ocupa 5º lugar de >90 ranking riesgo específico volcanes activos Chile. Por tanto, comprender las percepciones del puede ser fundamental para la gestión toma decisiones durante futuras erupciones. Este artículo examina narrativas habitantes asentamientos rurales Puyehue comparten zona influencia CVPCC, los cuales fueron seleccionados mediante muestreo cadena entrevistas profundidad.
