On this date 36 years ago, Mount St. Helens erupted, exploding with a force equivalent to about 1,600 atomic bombs of the type dropped on Hiroshima.

Is a volcano more powerful than a nuclear bomb?
Tonga volcano eruption released more energy than the most powerful nuclear bomb. The eruption of the underwater volcano in Tonga that triggered a tsunami earlier this year (January 2022), released more energy than the Tsar Bomba – the most powerful nuclear bomb ever detonated – according to a new study.
When Mount Saint Helens erupted how many Hiroshima bombs was the energy?
The total energy output on May 18 was equivalent to 400 million tons TNT, approximately 20,000 Hiroshima-size atomic bombs. On Hay 18 and also during later eruptions critical energy thresholds were exceeded by potent geologic processes which were able to accomplish significant changes in short order.
How powerful was Mt St Helens?
The eruption produced a force equal to 10–50 megatons of TNT, the equivalent of 25,000 atomic bombs released over the city of Hiroshima during World War II, and superheated gas and rock exploded out of the volcano sideways at speeds of up to 400 mph.
How many times Mt St Helens exploded?
Helens has been the most active Cascade Range volcano, with about 20 eruptive periods. Over the millennia, debris avalanches, pyroclastic flows, lava flows, and mudflows have built, torn apart, and rebuilt the volcano. From the May 18, 1980, eruption to 1986, the volcano erupted an additional 21 times.
How many atomic bombs was Mount Saint Helens?
In total, Mount St. Helens released 24 megatons of thermal energy, seven of which were a direct result of the blast. This is equivalent to 1,600 times the size of the atomic bomb dropped on Hiroshima.
How many megatons was Mt St Helens eruption?
Helens eruption of 18 May 1980. Wave signatures were similar to those of waves from large nuclear explosions. Independent theoretical and empirical analyses indicate that the explosive yield of the eruption was approximately 35 megatons.
What’s worse than a nuclear bomb?
But a hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb, according to several nuclear experts. The U.S. witnessed the magnitude of a hydrogen bomb when it tested one within the country in 1954, the New York Times reported.
Could a nuke set off Yellowstone?
Could a nuclear explosion on Yellowstone cause it to errupt? Perhaps. The Yellowstone Reservoir is FAR beneath the surface, much too far out of reach of any nuclear crater. But a nuclear detonation COULD destabilize the Yellowstone area and cause an eruption.
Who dropped the largest atomic bomb?
the Soviet Union
On the morning of October 30, 1961, the Soviet Union carried out the Tsar Bomba test, a hydrogen bomb that was the most powerful nuclear weapon ever created and tested. The Tsar Bomba packed a punch of over 50 megatons, which is the equivalent of 50 million tons of conventional explosives.
How many nukes are equal to a volcanic eruption?
James Garvin, the chief scientist at NASA’s Goddard Space Flight Center, told NPR that they came up “with a number that’s around 10 megatons of TNT equivalent.” With an estimated explosive yield of 10 megatons of TNT equivalent, the volcano blast was equivalent to the force of roughly 667 “Little Boy” atomic bombs.
Which atomic bomb was the biggest?
The Tsar Bomba
The Tsar Bomba
Is Mount St. Helens bigger than Yellowstone?
The three caldera-forming eruptions at Yellowstone (2.1 million years ago, 1.3 million years ago, and 640,000 years ago), were respectively about 2,500, 700, and 1,000 times larger than the 1980 eruption of Mt. St. Helens in the state of Washington.
Did they know Mt. St. Helens was going to explode?
In 1980, Mt St. Helens’ continued seismicity warned scientists at monitoring stations that the volcano might erupt, but the danger zone around the mountain turned out to be much too small.
What president was killed by Mt. St. Helens?

Is Mt St Helens still active?
Mount St. Helens is the most active volcano in the contiguous United States, which makes it a fascinating place to study and learn about. Scientists receive many questions about the volcano.
How long did it take to clean up after Mount St. Helens?
Mount St. Helens: 40 Years of Recovery | Earth And The Environment.
Did any life survive the eruption of Mount St. Helens?
Life was obliterated near the Mount St. Helens crater after the blast. But scientists arriving shortly after the 1980 eruption were surprised to find that most frogs, toads, salamanders and newts actually survived in locations throughout the blast area.
Where was the largest atomic bomb dropped?
Novaya Zemlya
Tsar Bomba
30, 1961, the Soviet Union dropped the most powerful nuclear weapon ever exploded on the archipelago of Novaya Zemlya, north of the arctic circle.
Did the US have 3 atomic bombs in ww2?
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict.
Where was the 1 atomic bomb dropped?
of Hiroshima
On August 6, 1945, during World War II (1939-45), an American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima.
