Following a severe tornado earlier this year in Alabama that killed 23 people, scientists interviewed residents in the area to find out why the storm was so deadly and made an important finding: almost everyone had heard the warnings about the impending storm and had enough time to seek shelter, but some chose not to.

“From a national standpoint, a media standpoint, forecasters did a great job” predicting the March storm in eastern Alabama, Stephen Strader, an atmospheric scientist at Villanova University, said. “But why did we see 23 fatalities? Why didn’t they take shelter?”


These questions are a central part of new research that is being conducted in collaboration between physical scientists, like Strader, and social scientists to try to determine why people behave the way they do during a storm, including whether they choose to seek shelter or not.

The goal of the research is to provide more information to forecasters and policymakers to create better tornado warning systems. Strader said that as a physical scientist, his job is to look at all the physical factors of a storm, including “how wide was it, where did the tornado track, how many homes were damaged.”

He said social scientists, on the other hand, try to find out more information about people’s choices. “We want to understand the decision-making about tornado warnings. If a warning comes, what do you do?” he asked.

Social science

Kim Klockow, a scientist at the University of Oklahoma, is involved in the research as a social scientist and compares her field to medicine. “Everyone wants to know what treatment to pursue, but there needs to be a diagnosis first,” she said, adding that social science is like the diagnosing phase. In the aftermath of a storm, she said, “all we have is the death total, which doesn’t tell us much.”

When a death toll is low, like after a powerful tornado hit Kansas in May but left no fatalities, Klockow said people call it “a miracle.” However, she said even these situations are “frustrating, because we don’t know why” there were no fatalities.

The death rate from tornadoes in the United States had steadily decreased from 1920 to 1990, but since then has stalled, according to research Strader has done. The reasons for this are not well understood, Klockow said. Without more information, “it is hard to say why things are happening the way they are.” “What I’m advocating for is observation,” she said.

Mobile homes

The new research focuses primarily on people who live in mobile homes, as those structures are particularly vulnerable to tornadoes. Roughly half of the fatalities from the March tornado in Alabama were residents of mobile homes.

Strader said it is not just that a mobile home is more vulnerable to storms, but that the people living in them are often more disadvantaged and have more complexities in terms of their decision-making. He said they might not have a vehicle or might not know where to go.

The U.S. National Oceanic and Atmospheric Administration recommends people who live in mobile homes flee to a safer structure during a tornado, even if their mobile home is tied down, while those who live in traditional houses are advised to go to their basement, or if they do not have one, to an interior room.

Strader said there used to be a belief that people who lived in mobile homes were less educated about the weather. However, he said current research shows they know just as much about the weather as anyone else and are also aware that their mobile homes are not safe. However, sometimes they freeze or don’t know where to flee, he said. “There are a lot of issues we have to start dissecting,” he said.

Getting to safety

Strader suggested that the safest course of action would be for people in mobile homes to flee to safety at the first sign that a tornado could strike, when forecasters issue what is called a “tornado watch,” even before a tornado has formed and they announce a “tornado warning.”

He acknowledged, however, this could be a difficult choice for people to make. Strader said people have all kinds of belief systems and biases that could prevent them from seeking shelter, including a fatalistic attitude, thinking, “If I am going to die today, it will be today.’”

According to Klockow, people need to be motived with a little fear, which can drive them to action, but warned that too much fear can make people freeze.

“We can find people kneeling on the floor praying instead of trying to get to a shelter,” she said. Klockow said people tend not to blatantly disregard information about an incoming tornado, but said, “very often, people don’t feel that they need to do something about it.” (VOA)

Taliban-led government killed several former members of the Afghan National Security Forces.

The Taliban-led government, controlled today by the Haqqani Network, a loyal proxy of Pakistan, is in the news once again for having summarily killed several former members of the Afghan National Security Forces (ANSF). These killings and disappearances have been documented in a report recently published (December 4) by Human Rights Watch (HRW). The international condemnation of the actions of the Taliban demonstrate that the West is still far from recognising a regime well known for its brutal ways. That the US, European Union and 20 other countries condemned the Taliban over allegations of summary killings of former police and intelligence officers is a sure sign of continued global antipathy towards the Taliban regime in Afghanistan.

The statement echoing the sentiments of the world came after HRW's documentation (November 30) of the killing or disappearance of at least 47 members of the ANSF including military personnel, police, intelligence service members, and paramilitary militia, who had surrendered to or were apprehended by Taliban forces between August 15 and October 31. HRW said its research also showed that the Taliban have killed or forcibly disappeared more than 100 former members of the ANSF in the provinces of Ghazni, Helmand, Kunduz and Kandahar provinces. The main findings of the report come from the provinces of Ghazni, Helmand, Kandahar, and Kunduz provinces, but the cases reflect a broader pattern of abuses reported in Khost, Paktiya, Paktika, and other provinces.

Afghans were by far the largest group of applicants in the EU in September.

Afghans lodged more than 17,000 asylum applications in the EU in September, up from 10,000 in August and nearly twice as many as Syrians. This made Afghanistan by far the main country of origin, which Syria had been for seven years until July, the European Asylum Support Office (EASO) said.


Total applications in the EU exceeded pre-pandemic levels for the first time since the outbreak of Covid-19.

Aviation has revolutionised tourism and business forever, not to mention the cultural linkages that have been made possible.

International Civil Aviation Day is observed on December 7th to recognize the flying industry’s impact on modern society. In 1994, as part of ICAO’s (International Civil Aviation Organization) 50th-anniversary celebrations, the first International Civil Aviation Day was observed, and in 1996, the United Nations General Assembly declared December 7th as International Civil Aviation Day.
