Creating 3-D Maps of Complex Buildings for Disaster Management
In case of an emergency, first responders like the fire brigade need up-to-date information. 2D maps are a common source of information but they can be difficult to read in an emergency situation. A researcher has created an algorithm that can accurately generate 3D models of the insides of large buildings from point clouds.

Simple Actions May Help People Survive Landslides
An engineer who analyzed the aftermath of the March 2014 landslide in Oso, Washington, began to investigate the circumstances that can make landslides so deadly. The resulting study shows that certain human actions increase the chance of surviving a devastating event, and suggests simple behavioral changes could save more lives than expensive engineering solutions.

Intelligence Agencies Accuse Iran, Russia of Trying to Use Voter Registration Data to Sow Chaos Ahead of US Election
U.S. intelligence agencies are accusing Iran and Russia of trying to use voter registration data in “desperate attempts” to sow chaos and confusion ahead of the November 3 U.S. presidential election. In a hastily called news conference late Wednesday, Director of National Intelligence John Ratcliffe said that “We have confirmed that some voter registration information has been obtained by Iran, and separately, by Russia,” he said, adding both countries “have taken specific actions to influence public opinion relating to our elections.”

Securing the Critical Minerals Supply Chain
From the military to the technology sector, various American institutions and industries play a role in maintaining U.S. economic and national security. While the finished products associated with defense and technology, like aircraft engines and LED TVs, capture the public eye, the supply chains for the materials needed to produce these goods often garner little attention. Eli Nachmany writes that a set of minerals, known as critical minerals, constitute a key part of the supply chains for these important sectors. In recent years, however, U.S. competitors such as China have come to control supply chains for the critical minerals themselves—raising questions about the effects of critical mineral supply chain insecurity on U.S. national security.

Monitoring Space Debris
Swirling fragments of past space endeavors are trapped in orbit around Earth, threatening our future in space. Over time, the number, mass and area of these debris objects grows steadily, boosting the risk to functioning satellites. ESA’s Space Debris Office constantly monitors this ever-evolving debris situation, and every year publishes a report on the current state of the debris environment.

Climate Change Undermines Safety of Europe’s Buildings, Infrastructure
Buildings and infrastructure also need to adapt to the changing climate. Updating structural design standards is crucial to improving European climate resilience and ensuring the safety of constructions, that are expected to suffer from changes in atmospheric variables and more frequent and intense extreme weather events. The higher temperatures expected over the next 50 years in Europe will accelerate corrosion of buildings, and will expose infrastructure to higher stresses, thus undermining the safety of constructions.

The Accuracy of Tsunami Predictions
Residents of coastal towns in Chile remember the catastrophic earthquakes that struck their country in 1960 and 2010, not always for the quakes themselves but for the tsunamis that followed. New study validates accuracy in predicting the first wave, but weakness in forecasting ‘trailing’ waves.

Finding the Origins of a Hacker
Industrial control systems run utilities that provide the electricity to keep the lights on or that deliver the water that people expect to gush out when they turn on a tap. Today those systems can be attacked via malicious code that an adversary inserts into the normal operating instructions.

Curbing Earthquakes-Induced Economic Losses to Power Plants
Researchers have shown that during high seismic activity, the structural integrity of bushing systems can be better maintained by reinforcing their bases with steel stiffeners. Also, by using probability-based loss assessment studies, they found that the economic burden due to damage to bushing systems from earthquakes is up to 10 times lower for steel-reinforced transformer bushing systems compared to other bushing configurations.

Network Resilience is Key to Surviving Compound Hazard Events
As weather extremes such as Superstorm Sandy, which swamped New York City’s subway system in 2012, increase in frequency and intensity and as cybercriminals ramp up attacks on technologies that tie together urban infrastructure systems, networks critical to the flow of data, people, goods, and services must be made more resilient to failure

How Many People Will Migrate Due to Rising Sea Levels? Our Best Guesses Aren’t Good Enough
The idea that rising seas will force millions to move, unleashing a refugee crisis like no other, has now become commonplace. It’s a narrative that the media are fond of, but that does not mean it is based on evidence. The potential scale of sea level rise is becoming clearer, but this does not necessarily translate into population movements. Everything we have learned so far suggests that decisions to migrate are far more complex than a simple flight response.

Making Highways, Tunnels, and Bridges More Resilient to Extreme Events
The EU-funded RESIST project aims to provide a methodology as well as tools for risk analysis and management for critical highway structures (in the case of bridges and tunnels) that will be applicable to all extreme natural and man-made events, or cyber-attacks to the associated information systems. Its goal is to increase the resilience of seamless transport operation and protect the users and operators of the European transport infrastructure by providing them optimal information.
