A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
Hazards & Disasters
Space Weather Aviation Forecasting on a Global Scale
Under a new mandate, consortia of the world’s major space weather centers will disseminate new space-weather advisories for civil aviators representing a significant change-of-state for space weather.
Deforestation Could Exacerbate Drought in the Amazon
Researchers use high-resolution satellite images to parse the effects of land use changes on the energy balance between the rain forest and the atmosphere.
Exposing Los Angeles’s Shaky Geologic Underbelly
Current calculations might underestimate the susceptibility of Los Angeles to earthquake shaking, so researchers and volunteers are deploying seismic networks near the city to remedy a data shortage.
Equity Concerns Raised in Federal Flood Property Buyouts
The communities most in need of federal property buyouts after a flood are the communities least likely to get them.
Putting a Price on the Costs of Climate Related Health Impacts
Using examples from the year 2012, a new study estimates the health costs of deaths and illnesses associated with climate-sensitive events.
Gravel Gives Clues to the Strength of Paleotsunamis
The roundness of sediment deposits may shed light on how big tsunamis were in the past and how to evaluate hazards in the future.
Wildfires Affect Water Resources Long After the Smoke Clears
Wildfires affect watersheds in myriad ways, from reducing evapotranspiration to changing soil repellencies, but new research suggests impacts on snowpack and runoff are the most significant.
Heat Waves Are Blowing in the Wind
New research indicates that droughts in far-off places contribute to the amount of heat transported to regions experiencing heat waves.
Louise Kellogg: Geoscientist, Mentor, Science Communicator
The geoscientist, who studied Earth’s mantle and believed strongly in the power of mentoring, passed away in April.
