Phys.org / Stress-testing the Cascadia Subduction Zone reveals variability that could impact how earthquakes spread

The Cascadia Subduction Zone is unusually quiet for a megathrust fault. Spanning more than 600 miles from Canada to California, the fault marks the convergence of the Juan de Fuca and North American plates. While other subduction ...

Phys.org / Satellite data enable first global estimate of aerosol cloud cooling

Particles in the atmosphere, known as aerosols, cool the climate by acting as cloud condensation nuclei. The more cloud droplets form around these particles, the less sunlight penetrates a cloud. This cools the climate, although ...
