Disasters

We've all seen footage of disaster victims being hoisted into helicopters, in litter-type stretchers. It's not a good thing if those litters start spinning or swaying, though, which is what the thrust-vectoring Vita Rescue System is designed to stop.

Evolution occurs as species adapt to environmental pressures, and few environments exert pressures like the Chernobyl exclusion zone. A new study shows evolution in action as frogs within the radioactive region are turning blacker than those outside.

While scientists have already created tight-space-exploring robots based on snakes and cockroaches, rats are also highly adept at squeezing through narrow openings. They now have a robotic equivalent of their own, in the form of the SQuRo.

When arriving at a disaster site, one of the most crucial tasks is to locate any survivors who may be trapped in the debris. A new module is designed to let drones do so, by detecting the radio signals of victims' mobile phones.

A startup created specifically to develop machines for first responders, Company Six, has now unveiled its first creation, a rugged, video-streaming robot called ReadySight that can be tossed into hairy situations.

The frequency of natural disasters over the past two decades is almost double that of the 1980-1999 period, a new report from the UN has revealed, with extreme weather events driven by climate change accounting for a large portion of the uptick.

Toyota and Honda recently started testing a fuel-cell bus designed as a mobile power source for disaster relief. Now Nissan has driven out an emergency response vehicle based on its Leaf electric car that will also provide emergency power.

When disaster strikes, the power often goes out, and it may be a good while before it's restored. Toyota and Honda start testing the Moving e system this month, a fuel cell bus designed to serve as a mobile power source for disaster relief.

Searching for sources of potentially harmful radiation isn't a job that most people would want – so why not get a drone to do it? Well, a team of Czech engineers is currently developing just such an aircraft.

Despite raising the alert level weeks prior to the devastating events of Monday, the violent eruption on White Island was not one authorities were able to predict with any precision, owing to the type of delicate, steam-driven processes that led to its explosion.

Among the proposed uses for drones, one of the most compelling is the search for survivors at disaster sites. That process could soon be more efficient, thanks to a system that allows drone cameras to differentiate between living and dead bodies.

A field study of the deadly 2014 landslide in Washington State is providing new insights into how such large-scale slides operate. A team from the US Geological Survey did detailed measurements and sampling of the post-disaster site, allowing them to build a detailed timescale of the event.
