Community participation and strong social networks can aid preparedness to natural disaster such as tsunamis in vulnerable regions, shows new research conducted in the south of Thailand.
People who participate in social activities in their community are more likely to plan and prepare for future disasters, such as tsunamis, according to a new study published in the journal PLOS ONE.
The study was based on household surveys in tsunami-prone areas of Phang Nga, Thailand, a region which was hard hit by the 2004 Indian Ocean Tsunami, and which has been active in setting up tsunami early warning systems and disaster training programs.
“We found that in tsunami-prone areas, people who have participated in community activities are more likely to undertake disaster risk reduction actions,” says IIASA researcher Raya Muttarak, who led the study. “These include not only low-effort actions like following disaster-related news closely but also higher-effort actions like having a family emergency plan or having an intention to migrate.”
Previous IIASA research has shown that education, in particular women’s education, is connected with reduced vulnerability to natural disasters. The new study supports these findings, showing that in communities where more women had at least secondary school education, more people planned for disaster risk reduction. In addition, the researchers found a strong link between social engagement, or participation in social, sports, and religious activities in a community, and taking actions to prepare for a potential natural disaster.
“We don’t know if this is a causative link or whether people have some underlying characteristic that leads to these behaviors,” says Nopphol Witvorapong, an economist at Chulalongkorn University in Bangkok, Thailand and study co-author.. However, he says, the study is one of the first to account for unobserved characteristics and show evidence for a link between social activities and disaster preparedness, and suggests that further research is needed.
“While there is increasing discussion about the role of social engagement in disaster preparedness, until now there has been little evidence-based research on the topic,” says Wiraporn Pothisiri, a demographer at Chulalongkorn University. In order to gather such data, Pothisiri and Muttarak carried out a household survey of over 500 families in Phang Nga immediately after the 2012 Indian Ocean earthquakes using the earthquake events as a test for disaster preparedness in the region.
The researchers then analyzed the data using a statistical model to explore whether there were links between social engagement in the community, and disaster preparedness efforts including following disaster-related news closely, preparing a family emergency plan or a disaster supplies kit, or planning to migrate to a lower risk area.
The researchers say that community activities and social networks cannot replace early warning systems and disaster training, but rather that they can complement and promote diffusion of such efforts.
“Our research suggests that the success of these disaster reduction efforts may depend on social cohesion and networks in a community. Promoting bottom-up disaster reduction strategies will be more sustainable than the top-down ones,” says Witvorapong

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
