Disturbances calls for disaster: Why forest fires increase landslides and rockfall hazards

The last thing you want after a forest fire is the imminent threat of natural hazards such as rockfall or landslide. Unfortunately, however, this is quite likely. Fire-injured trees may die, their roots may fail to bolster soil strength, and the ground can easily give way. Built-up areas below forested slopes are especially susceptible, and lives could be in danger. […]

Are wildfires following bark beetles more severe?

Bark beetles are responsible for large numbers of dead trees in ponderosa pine forests in the United States. The relationship between tree mortality caused by bark beetles and increasingly severe wildfires has been analysed by Carolyn Sieg and colleagues using a detailed physics-based fire behaviour model. The team seeks to understand if fires that follow beetles are more severe, that […]
