The Biggest Ammonium Nitrate Explosions since 2000

This week, a massive explosion involving ammonium nitrate rocked the city of Beirut, sending shock waves through the media.

This recent tragedy is devastating, and unfortunately, it’s not the first time this dangerous chemical compound has caused widespread damage.

Today’s graphic outlines the biggest accidental ammonium nitrate explosions over the last 20 years.

A Brief Explanation of Ammonium Nitrate

Before getting into the details, first thing’s first—what is ammonium nitrate?

Ammonium nitrate is formed when ammonia gas is combined with liquid nitric acid. The chemical compound is widely used in agriculture as a fertilizer, but it’s also used in mining explosives. It’s highly combustible when combined with oils and other fuels, but not flammable on its own unless exposed to extremely high temperatures.

It’s actually relatively tough for a fire to cause an ammonium nitrate explosion—but that hasn’t stopped it from happening numerous times in the last few decades.

The Death Toll

Some explosions involving ammonium nitrate have been deadlier than others. Here’s a breakdown of the death toll from each blast:

YearLocationCountryDeaths
2015TianjinChina165
2004RyongchonNorth Korea160
2020BeirutLebanon157*
2007MonclovaMexico57
2001ToulouseFrance30
2003Saint-Romain-en-JarezFrance26
2004MihăileştiRomania18
2013WestUnited States15
2004BarracasSpain2
2014WyandraAustralia0

*Note: death count in Beirut as of Aug 6, 2020. Casualty count expected to increase as more information comes available.

One of the deadliest explosions happened in Tianjin, China in 2015. A factory was storing flammable chemicals with ammonium nitrate, and because they weren’t being stored properly, one of the chemicals got too dry and caught fire. The blast killed 165 people and caused $1.1 billion dollars in damage.

In 2001, 14 years before the explosion in Tianjin, a factory exploded in Toulouse, France. The accident killed 30 people and injured 2,500. The power of the blast was equivalent to 20 to 40 tons of TNT, meaning that 40 to 80 tons of ammonium nitrate would have ignited.

In addition to factory explosions, there have been several transportation accidents involving ammonium nitrate. In 2007, a truck in Mexico blew up and killed over 57 people. Filled with explosives, the truck crashed into a pickup, caught fire, and detonated. The blast left a 60-foot long crater in its wake.

The Aftermath

While there have been several ammonium nitrate accidents throughout history, the recent tragedy in Beirut is one of the largest accidental explosions ever recorded, with 157 deaths and 5,000 injuries and counting.

In terms of TNT equivalent, a measure used to gauge the impact of an explosion, it ranks in the top 10 of the largest accidental explosions in history:

Topping the list is yet another ammonium nitrate explosion, this time back in 1947.

Known to history as the Texas City Disaster, the port accident was one of the biggest non-nuclear explosions to occur in history. The explosion killed over 500 people and injured thousands. The impact from the blast was so intense, it created a 15-foot wave that crashed along the docks and caused flooding in the area.

A Resource With Trade-Offs

Despite being dangerous, ammonium nitrate is still a valuable resource. There’s been an increased demand for the chemical from North America’s agricultural sector, and because of this, ammonium nitrate’s market size is expected to see an increase of more than 3% by 2026.

Because of its increasing market size, it’s more important than ever for trade industries to enforce proper safety measures when storing and transporting ammonium nitrate. When safety regulations aren’t followed, accidents can happen—and as we saw this week, the aftermath can be devastating.

10 Travel Destinations for Post-Pandemic Life

On March 11, 2020, the World Health Organization formally classified the COVID-19 outbreak as a pandemic. The resulting travel bans decimated the tourism industry, and international air travel initially fell by as much as 98%.

Almost two years later, travel is finally back on the table, though there are many restrictions to consider. Regardless, a survey conducted in September 2021 found that, as things revert to normalcy, 82% of Americans are looking forward to international travel more than anything else.

To give inspiration for your next vacation (whenever that may be), this infographic lists the 10 most visited countries in 2019, as well as three of their top attractions according to Google Maps.

Bon Voyage

Here were the 10 most popular travel destinations in 2019, measured by their number of international arrivals.

CountryNumber of international arrivals in 2019 (millions)
🇫🇷 France*90.0
🇪🇸 Spain83.5
🇺🇸 U.S.79.3
🇨🇳 China65.7
🇮🇹 Italy64.5
🇹🇷 Turkey51.2
🇲🇽 Mexico45.0
🇹🇭 Thailand39.8
🇩🇪 Germany39.6
🇬🇧 United Kingdom39.4

France was the most popular travel destination by a significant margin, and it’s easy to see why. The country is home to many of the world’s most renowned sights, including the Arc de Triomphe and Louvre Museum.

The Arc de Triomphe was built in the early 1800s, and honors those who died in the French Revolutionary and Napoleonic Wars. In 1944, Allied soldiers marched through the monument after Paris was liberated from the Nazis.

The Louvre Museum, on the other hand, is often recognized by its giant glass pyramid. The museum houses over 480,000 works of art, including Leonardo da Vinci’s Mona Lisa.

Art isn’t the only thing that France has to offer. The country has a reputation for culinary excellence, and is home to 632 Michelin-starred restaurants, the most out of any country. Japan comes in at second, with 413.

While You’re There…

After seeing the sights in Paris, you may want to consider a visit to Spain. The country is the southern neighbor of France and is known for its beautiful villages and beaches.

One of its most impressive sights is the Sagrada Familia, a massive 440,000 square feet church which began construction in 1882, and is still being worked on today (139 years in the making). The video below shows the structure’s striking evolution.

At a height of 172 meters, the Sagrada Familia is approximately 52 stories tall.

Another popular spot is Ibiza, an island off the coast of Spain that is famous for its robust nightlife scene. The island is frequently mentioned in pop culture—Netflix released an adventure/romance movie titled Ibiza in 2018, and the remix of Mike Posner’s song I Took a Pill in Ibiza has over 1.4 billion views on YouTube.

Beaches Galore

If you’re looking for something outside of Europe, consider Mexico or Thailand, which are the 7th and 8th most popular travel destinations. Both offer hot weather and an abundance of white sand beaches.

Expect Turbulence

Under normal circumstances, hundreds of billions of dollars are spent each year by international tourists. According to the World Travel & Tourism Council (WTCC), this spending accounted for an impressive 10.4% of global GDP in 2019.

Travel restrictions introduced in 2020 dealt a serious blow to the industry, reducing its share of global GDP to 5.5%, and wiping out an estimated 62 million jobs. While the WTCC believes these jobs could return by 2022, the emerging Omicron variant has already prompted many countries to tighten restrictions once again.

To avoid headaches in the future, make sure you fully understand the rules and restrictions of where you’re heading.

Which Values Children Should Be Encouraged to Learn, By Country

Which qualities do people think are most important for children to learn? The answer differs from country to country.

Published

on

Qualities Children Should Learn

Many of the values we prioritize as adults were instilled in us during our childhood days.

They’re called our formative years for a reason—from when we’re born up until we’re about eight years old, our brains are easily molded and remain highly sensitive to external influences and environments. But depending on where you grew up, you may have been exposed to different values during your childhood compared to someone from another place.

These visualizations by Anders Sundell illustrate the most important values people think children should learn at home, across more than 80 different countries.

Methodology

Sundell used data from the World Values Survey, an international survey that interviews hundreds of thousands of participants from across the globe. Respondents were asked to pick up to five qualities they believe are the most desirable for children to have:

  • Good manners
  • Independence
  • Hard work
  • Feeling of responsibility
  • Imagination
  • Tolerance and respect for other people
  • Thrift, saving money
  • Determination and perseverance
  • Religious faith
  • Unselfishness
  • Obedience

Sundell took the survey data and calculated the proportion of people in each country that selected each quality. From there, he took the top qualities and created three separate plot graphs to show the contrast between them.

Let’s look at the importance that countries placed on different values, including (1) independence and obedience, (2) unselfishness and religious faith, and (3) hard work and imagination.

1. Independence vs Obedience

Nordic countries value independence greatly, and find obedience to be a less important quality to instill in children.

Other available data also supports that adults in Nordic countries value independence. According to Eurostat, the most common age to leave home in Sweden is between 17 and 18—nearly a decade sooner than the average age across the EU (26 years old).

Denmark’s average age to leave home is also below the European average, at 21 years old.

On the other end of the spectrum, countries like Iraq and Egypt believe obedience is much more important for children to learn.

2. Unselfishness vs Religious Faith

Bangladesh, Egypt, and Jordan all place a strong emphasis on faith, and fall on the far right of this graph.

Islam is a strong influence in all three of these countries. In Bangladesh and Jordan, it’s the official state religion. And while Egypt is a secular country, a majority of citizens identify as Muslim—about 90% of the population.

Interestingly, places like the U.S. and Hong Kong fall right in the between, placing relatively equal importance on religion and unselfishness.

3. Hard Work vs Imagination

Left-leaning Nordic countries like Sweden, Norway, Denmark, and Finland think imagination is more important for children to learn than hard work.

Interestingly, Japan also scored high for imagination, seeing it was a more important value to teach children than hard work. This is despite the fact that the country has an international reputation for being a hardworking country, where even taking an extended vacation can be frowned upon. Then again, Japan has a reputation for producing wildly creative works of art that are popular internationally (anime, for instance).

As expected, countries and cultures contain multitudes, and can often seem paradoxical and complex to those who try to codify them.

What qualities do you think are most important, and what countries surprised you with their placements?
