Fire From Volcanic Activity: Quantifying the threat from an ...
2023年12月1日 · However, fire from volcanic activity (FFVA) is a highly dangerous and largely understudied hazard arising from volcanic activity. To demonstrate the potential destructiveness of this hazard, we develop a FFVA ignition probability model underpinned by a widely applicable fault tree, which identifies the mechanisms that can lead to fire ignition ...
The effect of growth, deforestation, forest fires, and volcanoes on ...
2024年6月10日 · The fire data provides fire radiative power (FRP), inferred source of fire, and fire type by location and time measured in megawatts (MW). The cut-off distances are 300 km for forest fires and 50 km for volcanic activities from the centre of the cities.
Fire From Volcanic Activity: Quantifying the threat from an ...
Fire from volcanic activity (FFVA) is a highly dangerous and largely understudied hazard arising from volcanic activity. FFVA can be caused by a variety of volcanic hazards and can greatly compound the damage and losses associated with volcanic activity, in addition to creating complications for event response and mitigation.
Soil erosion after fire in volcanic terrain: Assessment and ...
2023年10月1日 · Wildfires can dramatically modify the hydrologic and erosion response of ecosystems, increasing risks to population and assets downslope of fire affected hillslopes. This applies especially to volcanic areas in fire-prone regions which often exhibit steep terrain and high population densities.
Modeling shows fires from volcanic activity could greatly …
2023年9月27日 · The study concluded that under extreme wind conditions the spread of fire could increase the affected Auckland area to six times greater than from the volcanic eruption itself.
Learning from Fire at Lassen (U.S. National Park Service)
2024年12月20日 · The second journal article, coauthored by Niziolek, is about mediators of fire severity in the 2021 Dixie Fire. The Dixie Fire was California’s largest single fire to date, at 374,000 ha. The study explores how previous fire and fire suppression operations during the Dixie Fire affected how severely it burned through Lassen Volcanic National ...
Holocene vegetation change in relation to fire and volcanic …
2015年5月20日 · Volatiles erupted from large-scale explosive volcanic activities have a significant impact on climate and environmental changes. As an important ecological factor, the occurrence of fire is affected by vegetation cover, and fire can …
Evaluating the role of fire over a decade in a tropical mountainous ...
5 天之前 · Forest-grassland mosaics comprise a major component of tropical landscapes, hosting invaluable biodiversity and providing essential ecosystem services to hundreds of millions of people worldwide. While open biomes often benefit from disturbance, forests can particularly be susceptible to structural changes resulting from such disruptions. Here we evaluate the influence of fire on the structure ...
Human driven climate change increased the likelihood of the 2023 …
2024年12月20日 · For the fire weather or fire season metrics, anomalies were calculated relative to the first common 30 years (1951-1980) from each model; anomalies for the natural forcing simulations were ...
Volcanic activity, which is classified in EM-DAT as a geophysical hazard, occurs regularly throughout certain regions of the world, particularly in an area referred to as the “Ring of Fire” circling the Pacific Ocean. These events do not often cause catastrophes as they are either not severe or are in areas away from human settlement.
