Urban areas more likely to have precipitation-triggered landslides, exposing growing populations to slide hazards      (via sciencedaily.com) 

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.

Seismic forensics and its importance for early warning      (via sciencedaily.com) 

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.

Quantum networks in our future      (via sciencedaily.com) 

Investigators outline how a time-sensitive network control plane could be a key component of a workable quantum network. In addition to the well-understood requirements of transmission distance and data rate, for quantum networks to be useful in a real-world setting there are at least two other requirements that need to be considered. One is real-time network control, specifically time-sensitive networking. The second is cost.

One material with two functions could lead to faster memory      (via sciencedaily.com) 

Researchers have developed a new light-emitting memory device by integrating a resistive random-access memory with a light-emitting electrochemical cell that are both based on perovskite. The results are promising for faster data storage and reading in future electronic devices and open a new avenue of applications for perovskite optoelectronics.

Is your mobile provider tracking your location? New technology could stop it      (via sciencedaily.com) 

Right now, there is a good chance your phone is tracking your location -- even with GPS services turned off. That's because, to receive service, our phones reveal personal identifiers to cell towers owned by major network operators. This has led to vast and largely unregulated data-harvesting industries based around selling users' location data to third parties without consent. For the first time, researchers have found a way to stop this privacy breach using existing cellular networks. The new system protects users' mobile privacy while providing normal mobile connectivity.

Coastal wetlands are nature's flood defenses      (via sciencedaily.com) 

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 Science of tsunamis      (via sciencedaily.com) 

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.
