Natural Hazard

Global water resources are stretched by climate change and human population growth, and farms and cities are increasingly turning to groundwater to fill their needs. Unfortunately, the pumping of groundwater can cause the ground surface above to sink, as the aquifers below are drained and the architecture of the ground collapses. For the first time, ...

As cornfields suffer crop damage caused by weather, corn producers can use geospatial and remote sensing technologies to get a more accurate measurement of the damage and estimate potential economic loss, according to a recent study published in Frontiers in Agronomy. In the study, the United States Department of Agriculture’s (USDA), Agricultural Research Service (ARS) ...

Consultant Card Geotechnics (CGL) has applied aerial laser surveying to pinpoint natural hazards on development sites across the UK.

Canada’s fire forecasters will be getting a new tool in their battle against out-of-control blazes. In this year’s record-scorching fire season, provincial and federal wildfire agencies had to rely on a mix of European and NASA satellite instruments to help monitor and predict fire behaviour. Now, however, the Canadian Space Agency is preparing to launch ...

Flooding is the most frequent severe-weather related threat and the costliest natural disaster in the United States. To improve flood warning communication and help emergency managers prepare for and respond to flooding, the National Weather Service (NWS) has begun to add new experimental flood inundation mapping services to its suite of forecast products. These new ...

While some parts of the world suffer extreme heat and persistent drought, others are being flooded. Overall, continental water volumes vary so much over time that global sea levels fluctuate significantly too. By combining the hydrological model WaterGAP with GRACE satellite data, a team of geodesists at the University of Bonn have come up with ...

Le inondazioni rappresentano uno dei disastri naturali più comuni e più impattanti a livello mondiale. Tali eventi aumenteranno ulteriormente in futuro a causa dei cambiamenti climatici, della crescita economica e dell’urbanizzazione. I ricercatori del laboratorio LSD&D (Land Surface Dynamics and Degradation) del CNR-IMAA, unitamente a ricercatori dell’Università Federico II di Napoli, propongono un approccio innovativo ...

Analysis of Global Positioning System (GPS) time-series data from nearly 100 large earthquakes worldwide has provided evidence for the existence of a precursory phase of fault slip occurring two hours before seismic rupture. “If it can be confirmed that earthquake nucleation often involves an hours-long precursory phase, and the means can be developed to reliably ...

Landslides and rockfalls are increasingly becoming a real threat to people and infrastructure in light of the changing climate and the associated changes in soil and rock structure. The more precise the measurement, the earlier hazards can be detected, and consequently damage can be limited or even avoided altogether. A team at the Institute of ...

What was called the ‘wildfire risk map’ is now the ‘wildfire hazard map.’ The map is intended to educate homeowners about their exposure to wildfire risk, determine where fire mitigation resources should be prioritized and identify where future state rules on home hardening and defensible space will apply. The name change reflects a shift by ...

If you live in a community in the mountains like Valemount, McBride or Dunster, you are more than aware that rockfalls, landslides, mudslides and floods are facts of life, and as climate change is making those events more common, a new UNBC research project is looking at how mountain communities can better prepare for these ...

A new deep learning system can detect natural disasters using images posted on social media. The international group of researchers applied computer vision tools that, once trained using 1.7 million photographs, proved capable of analyzing, filtering, and detecting real disasters, writes the Universitat Oberta de Catalunya (UOC) in a press release. Previous research focused on ...
