Revolucionando la ciencia de los terremotos en Cascadia
Un nuevo centro reunirá a científicos de sismos para estudiar la zona de subducción de Cascadia y aclarar los peligros sísmicos.
Shaking Up Earthquake Science in Cascadia
A new center will bring together earthquake scientists to study the Cascadia Subduction Zone and clarify seismic hazards.
Natural Nitrogen Emissions Are Rising in California
Wildfires and soil microbes are releasing more nitrogen oxides in California as the climate gets warmer and drier.
Earthquakes Have Preparatory Stage Years Before Rupture
Tidally induced seismicity increased locally before the 2019 Ridgecrest earthquake, suggesting that fault sensitivity to stress increases in the years immediately before large earthquakes.
One Solution to the Climate Crisis: Better High School Education
Integrating Earth and space science into high school biology, chemistry, and physics courses may be the best way to educate the public about climate science.
Mudslides and debris flows triggered by Storm Hilary
Videos of debris flows and mudflows from Storm Hilary.
Lightning-Caused Wildfires are 80 Percent More Likely Under Dry Vegetation
Mimicking a randomized control trial of wildfires, scientists use satellites to uncover the key role of vegetation dryness in wildfire risk, aiding wildfire management and preparedness in California.
On-Again, Off-Again Lake Cahuilla Likely Enhanced Earthquakes in Southern California
The disappearance of the ephemeral lake has made earthquakes along the San Andreas Fault even more unpredictable.
Los beneficios desiguales de la transición a vehículos eléctricos en California
Un repunte en vehículos limpios ha mejorado más la calidad del aire en comunidades adineradas en comparación con comunidades marginalizadas de California, muestra un nuevo estudio.
