GIS-based analysis of fault zone geometry and hazard in an urban environment

October 24, 2019 0 Comments Earth Science, Earthquakes, Geoengineering, Geography, Geology, Landslides, Natural Disasters, Oceanography

Typical geologic investigations of active earthquake fault zones require that the fault can be observed at or near the Earth's surface. However, in urban areas, where faults present a direct hazard to dense populations, the surface expression of a fault is often hidden by development of buildings and infrastructure. This is the case in San Diego, California, where the Rose Canyon fault zone trends through the highly developed downtown.

New flame retardants escaping from our TVs, other electrical and electronic products, and children's car seats are just as toxic as the flame retardants they're intended to replace, according to a new study. The authors found that the replacement chemicals, called organophosphate flame retardants, have been associated with lower IQ in children, reproductive problems, and other serious health harms.

Wrapping a building in a fire-protective blanket is a viable way of protecting it against wildfires, finds the first study to scientifically assess this method of defense. Rigorous testing reveals that existing blanket technology can protect structures from a short wildfire attack, but for successful deployment against severe fires and in areas of high housing density, technological advancement of blanket materials and deployment methods, as well as multi-structure protection strategies, are needed.
