Researchers found a high probability of flood damage -- including monetary damage, human injury and loss of life -- for more than a million square miles of land across the United States across a 14-year period.

The United States is expected to experience as much sea level rise by the year 2050 as it witnessed in the previous hundred years. That's according to a NOAA-led report updating sea level rise decision-support information for the U.S. released in partnership with half a dozen other U.S.federal agencies.

Field surveys conducted in the days after the 7 January 2020 Puerto Rico earthquake documented more than 300 landslides and severe liquefaction in southern coastal regions, according to a new study.

Climate change could result in the financial toll of flooding rising by more than a quarter in the United States by 2050 -- and disadvantaged communities will bear the biggest brunt, according to new research.

New research looks to improve prediction of brief but intense rainstorms that can cause devastating flash floods and landslides. Intense rain associated with narrow cold-frontal rainbands may last only a few minutes at a particular location, yet the rain can cause catastrophic flash flooding, debris flows and landslides, and can occur along with tornadoes and severe thunderstorms.

The dramatic collapse of Indonesia's Anak Krakatau volcano in December 2018 resulted from long-term destabilising processes, and was not triggered by any distinct changes in the magmatic system that could have been detected by current monitoring techniques, new research has found.

New research examining whether forests can mitigate flood risk suggests they may offer less protection against major events than had been hoped. Although the work, which was carried out in forest sites in Ireland and the UK, showed forests can suppress small storm flows it also underlined that they are likely to make minimal difference in reducing the devastating impacts of major flood events.

Understanding how climate change will affect the flooding of rivers may become easier with a new framework for assessing flood risk that's been developed by an interdisciplinary team.

Rising oceans get more attention in climate change discussions, but rivers are rising, too, according to new research. The research shows that rivers need more attention in policy management and disaster preparation, both at the coast and farther inland.

Researchers outline how they were able to establish a clear pattern between the strength of the monsoon season in Nepal and the amount of landsliding over a 30-year period between 1988 and 2018.

Urban areas may be at greater risk for precipitation-triggered landslides than rural areas, according to a new study that could help improve landslide predictions and hazard and risk assessments. Researchers found that urban landslide hazard was up to 10 times more sensitive to variations in precipitation than in rural areas.

A new study speaks to the importance of public awareness programs in keeping residents -- and emergency management offices -- informed about rare but potentially lethal natural events in their area.

The catastrophic rockslide of February 7, 2021, in India's Dhauli Ganga Valley and the subsequent flood killed at least a hundred people and destroyed two hydroelectric power plants. Researchers traced the disaster minute by minute using data from a network of seismometers. The team posits that seismic networks could be used to establish an early warning system for high mountain regions.

New research shows how deforestation and population growth have greatly impacted landslide risk in the Kivu Rift. This is what researchers established from an analysis of six decades of forest cover and population trends in the region.

Researchers examined the number of households unable to pay for damages from coastal flooding to reveal how sea-level rise could threaten the fabric of Bay Area communities over the next 40 years.

Coastal wetlands -- such as salt marshes -- provide even more flood protection than previously thought, reducing risks to lives and homes in estuaries, a new study reveals. Research showed that wetlands that grow in estuaries can reduce water levels by up to 2 meters and provide protection far inland.

The word 'tsunami' brings immediately to mind the havoc that can be wrought by these uniquely powerful waves. The tsunamis we hear about most often are caused by undersea earthquakes, and the waves they generate can travel at speeds of up to 250 miles per hour and reach tens of meters high when they make landfall and break. They can cause massive flooding and rapid widespread devastation in coastal areas, as happened in Southeast Asia in 2004 and in Japan in 2011.

Converting Central American tropical forests into agricultural land is changing the color and composition of natural material washing into nearby rivers, making it less likely to decompose before it reaches the ocean, a new study has shown.

Puerto Rico is not ready for another hurricane season, let alone the effects of climate change, according to a new study that shows the island's outstanding capacity to produce record-breaking floods and trigger a large number of landslides.

Researchers hope industry and governments worldwide will use the SSSAFE model to help early warning systems mitigate landslide risks
