Simulations show how wildfire smoke increases atmospheric stability inside some valleys, creating a feedback loop that prevents its dispersion.
Hazards & Disasters
The Infrastructure Impacts of Solar Storms
A new book brings together insights from the space weather, geophysics, and power engineering communities to understand the characteristics and impacts of geomagnetically induced currents.
Earthquake Statistics Vary with Fault Size
A theoretical study explores why small earthquake sources can produce quasiperiodic sequences of identical events, whereas earthquakes on large faults are intrinsically more variable.
The Bigger They Are, the Harder They Fall
New research tracking 1.8 million trees found that tall trees died at more than twice the rate of smaller ones toward the end of extreme and persistent drought.
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.
