A recent study, published in the Water Resource Research journal, presents a new method for a spatially realistic national flood risk assessment.

Researchers expanded an existing statistical model, based on U.S. Geological Survey (USGS) river flow data, to simulate a thousand years of potential flood events. By calculating the damage for each event in dollars, they were able to estimate the probability of the United States suffering particular annual flood damages.

Traditional risk flood analysis models assume that the impacts on the entire flood-affected... read more

FV3: Finite-Volume Cubed-Sphere Dynamical Core

In June 2019, NOAA upgraded its flagship weather model, the Global Forecast System (GFS), with a new dynamic core, called Finite-Volume Cubed-Sphere Dynamical Core (FV3). This upgrade of the GFS will enhance global numerical weather forecasting and better forecast precipitation, heavy rainfall and weather types at both regional and global level. Besides, the FV3-based GFS revealed improvements in predicting the track and intensity of tropical cyclones compared to the older GFS.

Combining the superior dynamics of global climate modeling with the everyday reliability and speed of operational numerical weather forecasting, the latest weather model upgrade makes the new... read more

Synthetic aperature radar patterns of seismic deformations associated with a model earthquake on the San Francisco section of the San Andreas Fault.

Earthquakes are a major concern in increasingly populated regions, however their prediction is a difficult task. Researchers have recently made progress in the use of complex simulation and modeling techniques to better forecast the occurrences of earthquakes.

In a recent study, researchers used Gradient Boosted Regression Trees, a machine learning technique for regression and classification problems that incorporates training data, to better determine spatiotemporally complex loading histories within subduction zones. The researchers simulated tens of earthquakes using a small‐scale experimental replica of a subduction zone and show that machine learning predicts well the timing and size of laboratory... read more

Air photo of the Mud Creek landslide, taken on May 27, 2017.

While several studies have already highlighted how global warming and its consequences are predicted to increase the frequency and magnitude of geohazards such as landslides, the relation between ongoing climate shifts and landslide behaviour is still difficult to assess, especially due to uncertainties in both models. In a new research paper, researchers at NASA's Jet Propulsion Laboratory and collaborating institutions have now documented the transition of a stable, slow-moving landslide into catastrophic collapse for the first time.

Their  observations lasted eight years and took place on the California Coast Ranges, which, due to their... read more

A destructive wildfire burned through Canada’s Northern Alberta region, destroying neighborhoods in Fort McMurray and displacing nearly 90,000 people.  The fire began on the 1st of May and the exact cause is still unknown. High temperatures and strong winds pushed it north-east two days later. Despite the work of more than 500 firefighters, by the 8th of May the fire had burnt 1,610 square kilometers of forest. By the 24th, the fire was still not extinguished but it had not grown either.
