New research reveals more about the magnitude of January eruption, as researchers call for better preparedness The eruption of the Hunga Tonga-Hunga Ha'apai volcano in January created an initial wave 90 meters high -- almost the height of the Statue of Liberty (93m). Tsunami expert calls for better warning systems to detect volcanic eruptions, saying systems are '30 years behind' comparable earthquake detection tools.

A new paper by dozens of wildfire experts across the nation highlights the need for a more strategic and interdisciplinary approach to pursuing wildfire research and protecting vulnerable communities.

While funding is pumped into preventing low-probability scenarios such as asteroid collision, the far more likely threat of a large volcanic eruption is close to ignored -- despite much that could be done to reduce the risks, say researchers.

Researchers have developed the first long-term climatology of dry lightning -- lightning which occurs with less than 2.5mm of rainfall -- in central and northern California.

New research linking air pollution data from federal monitors in the Sacramento area of California, including during significant fires, is showing ill effects of pollution exposure among children, a new study suggests.

Researchers have discovered that super-eruptions occur when huge accumulations of magma deep in the Earth's crust, formed over millions of years, move rapidly to the surface disrupting pre-existing rock.

With fires raging from California to Alaska, the 2022 wildfire season is off to a violent start. It's an ominous sign of what promises to be another record-breaking fire season in the U.S. Roughly 2 million acres burned last month. And major fires are currently scorching Idaho, Utah and California, threatening tens of thousands of Americans' homes and livelihoods. Many of those at risk are lower-income Americans who face canceled homeowners insurance policies and rising premiums, according to new research.

Aerosol particles in the atmosphere have a bigger impact on cloud cover -- but less effect on cloud brightness -- than previously thought, new research shows.

Sea ice and wildfires may be more interconnected than previously thought, according to new research.

In recent years the plumes of smoke crawling upward from Western wildfires have trended taller, with more smoke and aerosols lofted up where they can spread farther and impact air quality over a wider area. The likely cause is climate change, with decreased precipitation and increased aridity in the Western U.S. that intensifies wildfire activity.

Researchers have augmented a physics-based numerical model to investigate and predict areas susceptible to debris flows. This augmented model eventually could be used in an early warning system for people living in high-risk areas, enabling them to evacuate before it's too late. Information from model simulations also could be used to design new infrastructure -- such as diversion bars that deflect fast-moving water away from homes and roads -- for high hazard zones.

A team of investigators devised a new methodology to enable predictions of how plant growth and water quality would change in the wake of wildfires.

Computers can be trained to better detect distant nuclear detonations, chemical blasts and volcano eruptions by learning from artificial explosion signals, according to a new method.

New research refining the amount of sunlight absorbed by black carbon in smoke from wildfires will help clear up a long-time weak spot in earth system models, enabling more accurate forecasting of global climate change.

Cats injured in California wildfires are at risk of forming deadly blood clots, according to new research.

The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state's climate-change solution arsenal may be in jeopardy, as new research reports that trees in California's mountain ranges and open spaces are dying from wildfires and other pressures -- and fewer new trees are filling the void.

Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may lead to speedier predictions of these giant waves.

Researchers used a fiber optic cable on the ice cap of an Icelandic subglacial volcano to detect low-frequency volcanic tremor, suggesting this technology could be useful in monitoring other ice-covered volcano systems.

As it captivated people around the world, the January eruption of the Hunga Tonga-Hunga Ha'apai volcano gave scientists a once-in-a-lifetime chance to study how the atmosphere works, unlocking keys to better predict the weather and changing climate.
