At least 113 people were killed and more than 4,000 were injured after a warehouse explosion sent a blast across Beirut on Tuesday.
Lebanese rescue workers are searching for survivors in the mangled wreckage of buildings, and investigators blamed negligence for the explosion.
Tens of thousands of people have been left without homes to live in.
Lebanese President Michel Aoun said 2.75 kilotons of ammonium nitrate, used for fertilizer and bombs and stored at the port for six years without safety measures, exploded.
The images were apocalyptic. How does the Beirut explosion compare to some other major blasts throughout world history, in terms of the size of blast and human toll? Below is a comparison:
Halifax Harbour Explosion (1917)
Kilotons: 2.9 kilotons
Death toll: 1,963 people
Injuries: 9,000 people
The Mont Blanc, a French vessel loaded with 2.9 kilotons of explosives, collided with the Belgian relief ship, Imo, in Halifax harbour on Dec. 6, 1917. A fire broke out on the Mont Blanc, which firefighters tried to extinguish. The flames reached the Mont Blanc’s cargo, and an explosion that had a 2.9 kiloton blast was created.
The official death toll from the Halifax explosion was 1,963 people. Nine thousand people were injured, 6,000 people were left homeless.
Bombing of Hiroshima (1945)
Kilotons: 12 to 15 kilotons
Death toll: 80,000 people
Injuries: Tens of thousands
An American B-29 bomber during the Second World War dropped the world’s first atomic bomb on Hiroshima, Japan, on August 6, 1945. The bombing killed 80,000 people, but tens of thousands were sickened with radiation exposure, and would later die from it.
The blast destroyed five-square miles of the city.
Chernobyl nuclear accident (1986)
Kilotons: 0.3 kilotons
Death toll: 30 people
Injuries: 6,500 injuries
The Chernobyl accident on April 26, 1986, happened because of a flawed nuclear reactor design that was operated with inadequately trained staff. The steam explosion and fires coming from the reactor created a 0.3 kiloton blast.
Thirty people were killed in the Chernobyl accident, but a further 6,500 people developed thyroid cancer from the radiation that was released.
Oklahoma City bombing (1995)
Kilotons: 0.0025 kilotons
Death toll: 168 people
Injuries: Several hundred
Timothy McVeigh, a former army soldier and security guard, detonated a bomb made out of agriculture fertilizer, diesel fuel and other chemicals inside a vehicle next to the Alfred P. Murrah Federal Building in downtown Oklahoma City on April 19, 1995.
The death toll from the Oklahoma City Bombing was 168 people. Several hundred people were injured. It was the worst act of home-grown terrorism in U.S.history.
Lac-Megantic, Quebec rail disaster (2013)
Kilotons: 0.0001 kilotons
Death toll: 47 people
Injuries: Hundreds
A runaway train hauling 72 tankers filled with crude oil derailed as it approached the centre of Lac-Megantic, Que., on July 6, 2013.
Almost six million litres of crude oil leaked from the tankers that derailed and exploded, creating a blast equal to 0.0001 kilotons that killed 47 people and destroyed many buildings and other infrastructure in the town’s centre.
Years after the derailment, rebuilding is ongoing on Lac-Megantic, and hundreds of the town’s residents continue to suffer from post-traumatic stress.
