New low-cost camera could help scientists forecast volcano eruptions affecting millions

By Deborah Pirchner, Frontiers science writer Image: Shutterstock.com Monitoring emissions from volcanoes – particularly sulfur dioxide (SO2) using specialized cameras – is important for hazard forecasting. Gathering long-term time series datasets is critical because volcanoes can exhibit significant changes in activity over time. Now, researchers have developed a cheap and low-power SO2 camera suited for long-term measuring. The tool could have significant implications for millions of people worldwide who live close to active volcanoes, they say. Gas emissions are the manifestation of activity occurring beneath the surface of a volcano. Measuring them lets researchers see what can’t be seen from the surface. This knowledge is vital for hazard monitoring and the prediction of future eruptions. Since the mid-2000s, ultraviolet SO2 cameras have become important tools to measure emissions. The measurement campaigns, however, must be accompanied by a user, making SO2 cameras unsuitable for acquiring long-term datasets. Building and operating this type of camera can cost upwards of $20,000, resulting in very few cameras being installed permanently. To get better long-term monitoring data, an international team of researchers has developed an SO2 camera to continually measure emission rates from volcanoes. They have now published an article about the camera design and two […]

In 2011, the Tohoku earthquake created a series of huge tsunami waves, which damaged coastal communities killing more than 17,900 people, forcing more than 50,000 households to relocate, and caused the Fukushima nuclear power plant failure, a nuclear disaster second only to Chernobyl in Russia in 1986, but which spread radiation across the Pacific Ocean.

The losses that come after the earthquake: devastating and costly

A study, published in Frontiers in Built Environment, explores the economic losses associated with the secondary effects of earthquakes.

Sustainable and resilient structural design to combat earthquake disturbances

By Eva Brown, Frontiers Science Writer To help buildings become more resilient to earthquakes, scientists have taken measures to analyze various vibrational modes with the goal of creating safe and sustainable structures for future generations. Professor Izuru Takewaki and his team based at Kyoto University in Japan have centered their studies around the areas of earthquake engineering and the structural design of buildings. They are working towards grasping an understanding of how best to bring resilience in buildings — especially against natural disasters such as earthquakes. Their aim is to create safer and more sustainable constructions. “During Japan’s Tōhoku earthquake and Tsunami in 2011, many people were killed, so I’m working on developing safe designs of buildings,” Takewaki explains. “In my field we are looking at the worst case analysis as you don’t know when, where or how intense a disaster will be.  We are also looking at the resilience of the buildings to withstand earthquakes.” In order to set the ground for progress, the team set out to measure the different vibrational states, which would enable them to develop safer building designs that are more stable and structurally secure. This, in turn, will enable the structures to withstand the […]

In the aftermath of disaster, social media helps build a sense of community

— By K.E.D. Coan Social media can disseminate critical information as well as unite disaster victims during their recovery efforts, suggests a study published in Frontiers in Communication. After natural disasters communities rely heavily on local governments to provide the necessary resources and information to respond to such disasters, but these approaches are not well equipped to meeting individual needs. As a complement to traditional methods, social media can provide a more personalized resource as well as fostering a sense of community in response to the crisis. “A relatively organized social media resource can go a long way to ensuring that people’s needs can be met;” said Douglas Paton, a professor of Psychology at Charles Darwin University and lead author of the study; “This is the first paper to explore whether people’s engagement through Facebook could translate into the development of more enduring, functional relationships.” Following a wildfire in Tasmania in 2013, the local community used a Facebook page developed by co-author Mel Irons, Tassie Fires – We Can Help, to relay details about disaster relief efforts and resources. The site also provided an opportunity for people to share their individual situations, needs, and reactions—and to connect with other people who […]
