There has been a lot of explosions in the world and today we are going to discuss the top 5 most powerful explosions in the world!

Humans have made tremendous improvements in the field of science and technology. And it has done human beings a lot of goodness in life. But along with the good comes the evil too. This advancement has along with it brought the capacity to destroy the world within a few seconds if the power to control it goes in wrong hands. There has been many wars and two world wars in the past. And because of the tensions rising among many countries in the name of border disputes and trade war, one wrong move from a powerful country and world will be torned apart.

Lets have a look at Top 5 Most Powerful Explosions the world has ever felt!

5. Beirut Explosion, Lebanon

Beirut Explosion that happened recently on 4th August 2020, is considered one of the most powerful explosions in the world. The explosion happened in Beirut, Lebanon where 2,750 tonnes of Ammonium nitrate were stored inappropriately since 2013. The explosion caused more than 185 deaths and over 6000 people got injured. The explosion left over 3 lakhs people homeless and caused property damage of more than 10-15 billion US dollars.

4. Halifax Explosion

Halifax explosion is also considered as one of the most powerful explosions in the world. It occurred on 6th December, 1917 in Halifax, Nova Scotia, Canada. It occurred when the French ship carrying a huge amount of explosives for the first world war from New York city collided with the Norwegian ship in narrow Halifax harbor. Total confirmed deaths in the Halifax explosion were 1950 and over 9000 people got injured in that explosion. Nearly all structures within the 800-meter radius including the community of Richmond were destroyed. It further caused a tsunami which wiped out the community of the Mikmaq First Nation who had lived in the Tuffs Cove area for many generations.

3. Chernobyl Disaster

Chernobyl after the Abandonment!

In the year 1986, a nuclear reactor exploded at Chernobyl in Ukraine, which was a part of the Soviet Union then. It is considered as one of the worst nuclear accident in the history. The blast blew the 2,000-ton lid off the reactor. It sent out 400 times more radioactive fallout than the Hiroshima bomb and ended up contaminating more than 77,000 square miles (200,000 square km) of Europe. About 600,000 people were exposed to high doses of radiation, and more than 350,000 people had to be evacuated from contaminated areas.

Cause of the Accident:

The reactor built at Chernobyl is a RBMK reactor, which was never built by any country outside the USSR because it had characteristics that were rejected everywhere outside the Soviet Union. Major reasons among these was its inherent instability, especially on startup and shutdown. Because of the way the reactor used graphite where American reactors use water, when Soviet operators tried to reduce power the RBMK had a tendency to sharply increase power production instead. As overheating became more severe, power increased even more.


In 2018, the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) reported that the accident also was responsible for nearly 20,000 documented cases of thyroid cancer among individuals who were under 18 years of age at the time of the accident in the three affected countries including Belarus, Ukraine and the Russian Federation. This was due to the high levels of radioactive iodine released from the Chernobyl reactor in the early days after the accident. Radioactive iodine was deposited in pastures eaten by cows who then concentrated it in their milk which was subsequently ingested by children. This was further exacerbated by a general iodine deficiency in the local diet causing more of the radioactive iodine to be accumulated in the thyroid.

2. Nagasaki Bombing

Plutonium Bomb “Fat Boy” dropped in Nagasaki, Japan

One of the most powerful explosions occurred in Nagasaki, Japan during the second world war. It happened on 9th August 1945, 3 days after the atomic bomb was dropped in Hiroshima. It was a Plutonium bomb named as fat boy by the American. The explosion resulted in death of more than 74,000 people. Most of the buildings collapsed in an instant. The bomb weighed nearly 10,000 pounds and was built to produce a 22-kiloton blast. The topography of Nagasaki, which was nestled in narrow valleys between mountains, reduced the bomb’s effect, limiting the destruction to 2.6 square miles. However the Nagasaki bombing was more powerful than Hiroshima bombing because of the topographical conditions the casualties were fewer than in Hiroshima.

In Nagasaki, the ground temperatures reached upto 4,000°C. Then the radioactive rain poured down. As a result, most victims died without any care and help to ease their suffering.

1. Hiroshima Bombing

Uranium Bomb “Little Boy” in Hiroshima, Japan

One of the most powerful explosions in the world happened in Hiroshima on 6th August, 1945. During the second world was America dropped a uranium bomb named Little Boy in Hiroshima. It was the first atomic bomb used in the war. It caused to the death of more than 1,40,000 people in Hiroshima. Both the nuclear bombs in Hiroshima and Nagasaki were detonated in the air in order to cover a larger geographical area. exploded 2,000 feet above Hiroshima in a blast equal to 12-15,000 tons of TNT, destroying five square miles of the city.

About 70% of all the buildings in Hiroshima were destroyed. Among 45 hospitals of Hiroshima 42 were damaged. Around 90% of the medical personnels of Hiroshima city were dead or injured. Because of which most of the injured died without any care. Other medical professionals and resuers that entered the city to help later died due to the high amount of radiation.


It takes few seconds to cause destruction, but the effects last for decades and span across generations. After Five to six years of the bombings, the incidence of leukemia increased noticeably among survivors of Japan bombing. After a decade also, survivors were suffering from thyroid, breast, lung and other cancers at abnormally higher rates. Pregnant women exposed to the bombings went through higher rates of miscarriage and mortality of their infant. The children born were having intellectual disabilities, impaired growth, and a higher risk of developing cancer. And for all survivors, cancers related to radiation exposure still continues to increase throughout their lifespan, even up to this day, seventy-three years later.
