Safe, efficient cookstoves for earthquake survivors
316,000 people were killed and more than one million made homeless by the 12 January 2010 magnitude 7.0 quake that left the capital city of Port-au-Prince in ruins; many of the displaced Haitians still live in tent cities, where even simple tasks such as cooking are a challenge; scientists hope to find the safest and most energy-efficient way for earthquake survivors to cook

Evaluating California earthquake forecasts
The Southern California Earthquake Center held a competition among seven different earthquake forecasts; an analysis of the competition shows that earthquake prediction remains an imperfect science, but the best forecasts are about ten times more accurate than a random prediction; the findings should help researchers both develop better earthquake forecasts and improve their tools for assessing those forecasts

Protecting structures against firebrand attack
NIST engineers have built a device that bellows showers of glowing embers, or firebrands, to test how structures can withstand this destructive aspects of wild fires; in Japan, where the device is now used in a test facility, firebrands are a growing peril that accounts for half of the nation’s ten most costly fires

Predicting race and ethnicity from irises now possible
Conventional wisdom holds that irises, like fingerprints, are unique to each individual and have little similarities between ethnic groups or gender, but a groundbreaking new study indicates that biometric scanners can actually predict race and gender based on iris texture alone; the study’s findings are important in that it opens new avenues for research that previously were not thought possible

U.S. intervention hinders disaster recovery, says reinsurance giant
Lloyd’s of London, the largest reinsurer of U.S. risk, said the federal government’s intervention in the insurance market could hinder recovery efforts following natural disasters; “We don’t believe that the U.S. has the balance between industry and government intervention right, you have government intervention in federal and state level, it demonstrates this is not a sustainable way to proceed,” said Lloyds general counsel

Better understanding of how tsunamis work
One of the obstacles to understanding how tsunamis work is the notion that it is the first wave that is the worst; researchers show that this is not the case, and that the second, third, or even fourth wave are often the most destructive

The long view
Proactively Planning for Community Relocation Before and After Climate Disasters
Between 1980 and mid-2023, 232 billion-dollar disasters occurred in the U.S. Gulf Coast region, with the number of disasters doubling annually since 2018. As the frequency, intensity, and destructiveness of climate change-driven disasters increase, accompanied by an increase in recovery costs, more experts are calling for a managed retreat of entire communities from disaster-prone areas to safer ground.
Number of People Affected by Tropical Cyclones Has Increased Sharply Since 2002
The number of people affected by tropical cyclones has nearly doubled from 2002 to 2019, reaching nearly 800 million people in 2019, according to a new study. More people are affected by tropical cyclones in Asia than any other region, but every affected world region saw an increase in the number of people exposed to tropical cyclones, which are expected to become more intense and possibly more frequent as the climate warms.
Coastal Populations Set to Age Sharply in the Face of Climate Migration
As climate change fuels sea level rise, younger people will migrate inland, leaving aging coastal populations — and a host of consequences — in their wake. While destination cities will work to sustainably accommodate swelling populations, aging coastal communities will confront stark new challenges.
Damaging Thunderstorm Winds Increasing in Central U.S.
Destructive winds that flow out of thunderstorms in the central United States are becoming more widespread with warming temperatures. New research shows that the central U.S. experienced a fivefold increase in the geographic area affected by damaging thunderstorm straight line winds in the past 40 years.
