Forest fires in California: Why trees stop and burn houses
Los Angeles, USA - The devastating forest fires in Los Angeles have triggered a shock wave that radically changes not only the landscape, but also the living situation of many people. Numerous houses suffer from the flames that burned down to the foundations, while the surrounding trees often remain intact. The social media users have made these unusual views to express conspiracy theory speculations about the causes of the fires, as the magazine . There are actually physical explanations for why buildings are more susceptible to fire than many tree species.
fire behavior and structural conditions
The highly flammable materials from which many houses consist of play a crucial role. According to Ernesto Alvarado from the Faculty of Environmental and Forestry, the tree species around the residential areas are often better equipped for such extreme conditions. They have developed thicker bark that better protect them from heat damage. In contrast, many houses made of easily flammable materials such as plastic are built, which can quickly ignite if they are exposed to a spark or embers. The National Fire Protection Association emphasizes the importance of the design design; In particular, the distance between trees and the cleanliness of the roofs are crucial for fire protection. All of this shows that the architecture and the living environment offer a larger area of attack for forest fires than the natural flora.
Another worrying element is the predictability of the fires monitored by the NOAA (National Oceanic and Atmospheric Administration). As Thiessen reports, many people don't even notice that they are in danger before it is too late. While some preventive measures are taken to minimize the consequential damage, many only have to wait. "The fire expires when the wind stops," he explains what illustrates the precarious situation for emergency services and residents.
