According to a study from the University of Wollongong, in Australia: Most likely there are roughly 70,000 nuclear bombs in the world. The exact number is unknown, due to military secrecy. The US has the most (or atleast the most documented)- estimates project that the US has 33,000 and the former USSR has around 16,000. Both nations continue to keep many in storage. Great Britain, France, China, India, Pakistan, and Israel among many other nations are known to possess these bombs. Under the Constitution of Japan the country has voluntarily banned itself from ever owning such a destructive weapon.
The bombs that were dropped on Hiroshima and Nagasaki were atomic bombs and not nuclear bombs and were designed to explode above the ground and not on impact.
The first atomic bomb was launched in 1945, by the US. It incinerated Hiroshima and Nagasaki, Japan during WWII The above is half true. That was the first time an atomic bomb was used in war, but the first atomic bomb was detonated at the the Trinity Site in White Sands Missile Range, on July 16, 1945.
Most of the bombs (and the V-1 and V-2 missiles) exploded above ground in London, which is why people took shelter in the subways and in basements. Unfortunately, some bombs were made heavy enough to penetrate the ground before exploding. Other bombs destroyed buildings which then collapsed into the subterranean shelters.
In very rough figures the B-29s were flying at about 30000 feet of altitude when they dropped the bombs and the bombs exploded at about 1500 feet of altitude. You can estimate from there.
The two bombs dropped on Japan were released at a little higher than 30,000 feet and exploded at about 1500 feet. You can calculate from there. Bombs dropped for test purposes have been released and exploded at different altitudes.

It is not possible to directly equate the energy released by an earthquake to the explosive power of atomic bombs. The Richter scale measures the magnitude of an earthquake based on seismic waves, while atomic bombs release energy through nuclear fission or fusion. The destructive power of an earthquake cannot be accurately converted to the number of atomic bombs.

The very first atomic bomb was exploded in a test in the New Mexico desert on July 16, 1945. If you'd like to look up more information about it, you can look up the codename "Trinity".
The atomic bomb was a bomb of mass destruction. The bomb was dropped on Japan twice before surrendering after a threat of another attack. The two bombs had the names of little boy and fat man. When the bombs exploded they demolished the buildings and vaporized the people also throwing radiation into the air making it uninhabitable where the bombs exploded. The bombs were dropped from the plane named Enola Gay the name of the pilot's mother.
America exploded a lot of atomic bombs the ones they dropped on Japan were to win the war and to see what would happen if they were dropped on real live people.
The planes carried bombs that exploded when the pilot crashed into targets.
The first two atomic bombs were set of in the atmosphere, they did not make a hole. Later during the cold war, regulations prevented atmospheric/surface testing and the bombs were set off in deep holes that were pre-drilled in the ground. These holes were as deep as the engineers made them.
Some atomic bombs explode on impact, most explode in the air for maximum destruction caused by the explosion spreading out over a wider area.
