More & higher yield atomic bombs, I guess.
As both atomic bombs and supernovas vary in yield, this question has no single answer.
Atomic bombs come in a wide variety of sizes. Their explosive power is usually measured in terms of an equivalent number of tons of dynamite. Smaller bombs range in the kilotons (thousands of tons) while larger bombs are in the range of megatons (millions of tons). Even a small atomic bomb is extremely powerful, much more powerful than any conventional bomb. A large atomic bomb can destroy an entire city.
Typical conventional bombs have explosive yields approximately equal to their physical weight, the largest yield conventional bomb of WW2 was the British Tallboy which weighed 6 tons and had a yield of nearly 3 tons. The first atomic bomb dropped in WW2 the Little Boy weighed just under 5 tons and had a yield of about 15000 tons equivalent. Comparing them, the first atomic bomb had a weight slightly less than the largest conventional bomb used in WW2 but the yield was about 5000 times larger!
As of August 9, 1945 the US had built a total of 3 atomic bombs and exploded all of them.As of August 14, 1945 the US had built another bomb which arrived in San Francisco on August 18, 1945; but as Japan was surrendering this bomb was returned to Los Alamos unused.The US had production plans and capability to build another 20 atomic bombs before the end of 1945.As of the end of Operation Crossroads in the summer of 1946 the US had built a total of 9 atomic bombs and exploded 5 of them.At the peak of the cold war the US had built several 10s of thousands of atomic bombs, exploded over a 1000 of them in test shots, and stockpiled more than 10000 of them. (Note: this counts only the high yield "strategic" weapons, at the same time the US had stockpiled roughly 30000 low yield "tactical" weapons. these were eliminated in the 1980s.)

The early ones were. However there are now small H-bombs with yields as low or lower than the original atomic bombs. They are cheaper to build per kiloton yield.
No. Hydrogen Bombs have been detonated that make the atomic bomb look small in comparison. The Atomic Bombs dropped on Japan in WW2 were 25 Kton (equivilent to 25000 tons of dynamite), while H bombs can be as big as several hundred Megaton (million tons of dynamite)

The first atomic bomb (The Gadget) was not used on any city. It was detonated on the top of a 100 foot tall steel tower, at the Trinity Site in the Jornada del Muerto desert about 35 miles southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range (now part of White Sands Missile Range) on July 16, 1945.The second atomic bomb (Little Boy) was the first to be used on a city. It was dropped by a B-29 above Hiroshima Japan on August 6, 1945.The third atomic bomb (Fatman, a deliverable version of The Gadget) was the second to be used on a city (and the first plutonium atomic bomb used on a city). It was dropped by a B-29 above Nagasaki Japan on August 9, 1945.The fourth atomic bomb (unnamed, identical to Fatman) had been manufactured by Los Alamos shortly after Fatman was used on Nagasaki and shipped to San Francisco, where a B-29 was waiting to fly it to Tinnian for use in a third attack on Japan sometime in late August. However as the Japanese indicated that they would surrender before this bomb arrived in San Francisco, president Truman issued an order that it be returned to Los Alamos instead of being loaded on the B-29 for Tinnian.All together the US had plans, facilities, and aircraft to manufacture and deliver a total of 23 atomic bombs on Japanese cities before the end of 1945:August - 3 atomic bombs (2 actually used); one MK-I uranium gun bomb (yield ~15 kilotons), two MK-III plutonium implosion bombs (yield ~22 kilotons)September - 3 atomic bombs; three MK-III plutonium implosion bombs (yield ~22 kilotons)October - 3 atomic bombs; three MK-III plutonium implosion bombs (yield ~22 kilotons)November - 7 atomic bombs; seven plutonium/uranium composite implosion bombs (estimated yield 30 to 40 kilotons)December - 7 atomic bombs; seven plutonium/uranium composite implosion bombs (estimated yield 30 to 40 kilotons)

The atomic bomb that was dropped on Hiroshima in 1945 had an explosive yield equivalent to approximately 15 kilotons of TNT. This explosion resulted in massive destruction and loss of life in the city.

can't say without knowing yield of bomb
When people talk about nuclear bombs, they are generally in two categories; atomic and thermonuclear. Atomic bombs are like the ones dropped on Japan in 1945.Thermonuclear bombs have never been used in warfare and involve using an atomic bomb to set off an explosion of a thermonuclear bomb, like a hydrogen bomb.IN ADDITION:The Soviet exploded the largest nuclear bomb to date back in 1961. It was a hydrogen bomb which released energy equivalent to 57 megatons of TNT. Compare that to the 15 kilotons of energy released by the first atomic bomb dropped on Hiroshima Japan during WWII ( 3,800 times more energy released). The name of this device was Tsar Bomba, meaning "king of bombs."
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.
