The explosions were caused by hydrogen gas mixing with the atmosphere in a contained system, and exploding. There are two ways this could happen.
When the tsunami hit, it basically wiped out all the cooling, power, and backup infrastructure at the plant. This caused reactors 1, 2, and 3 to overheat, and the water in the vessels boiled off to some degree. This led to a increased pressure in the pressure vessel from the steam that was being produced, and the pressure had to be released. The boiling water also exposed the fuel rods, however, and the zircaloy cladding reacts with steam, when it gets hot enough. This reaction produces hydrogen gas, which also is vented. The hydrogen mixed with the atmosphere in the reactor buildings, creating an explosive environment.
In these reactors, and also in building 4, where the reactor was not fueled up, the water in the spent fuel pools was not circulating and boiled. This could have exposed fuel rods, and probably did so in building 4. These rods can react with steam just as the rods in the reactor would, with the same result.

Did anymore problems arise after the tsunami earthquake in japan 2011?
The tsunami caused damage to the Fukushima Daiichi nuclear power plant resulting in a series of equipment failure, nuclear meltdows, and release of radioactive material into the environment.
What is the absolute location of the fukushima nuclear power plant?
Fukushima Daiichi (the worse accident) is located at 37° 25' 22.7" N 141° 01' 58.5" E. Fukushima Daini (the lesser accident) is located at 37° 18' 59" N 141° 01' 52" E.
What were the secondary effects of the Japan earthquake in 2011?
The secondary effects of the Japan earthquake were fires, gas line explosions, and a resulting major tsunami, which in turn was responsible for damage to the Fukushima Daiichi nuclear power plant. Destruction to plumbing and sewer system could led to disease due to build up of waste. Additional secondary effects were collapsed bridges and other structures due to destabilization caused by the strong shaking.
Which radioactive material element is used in nuclear reactor in fukushima japan plant?
The fuel rods are of uranium dioxide, with the uranium enriched to about 5% U-235
Is radiation still leaking from the nuclear power plant in Fukushima Japan?
US scientists determined this tear that the reactor is still leaking small amounts of radioactive materials into the ocean. The cleanup for this disaster could take as long as 40 years.
What is the name of the three nuclear power plant which suffered explosions on 11march 2011?
Fukushima in Japan
What nuclear power plant caused a series of explosions?
Churnoble
What is the Fukushima Power Plant?
There are two Fukushima power plants. Both are in the prefecture of Fukushima, Japan. The plant you have in mind is probably the Fukushima Daiichi Nuclear Power Plant, which experienced a series of meltdowns after an earthquake and tsunami of March 11, 2011. The other is the Fukushima Daini Nuclear Power Plant.
What has caused the destructive explosion in Fukushima?
The EarthquakeTsunamiLack of Electricity to keep the power plants coolThey say that the lack of cooling was one of the main reasons for the nuclear plant explosions and the authorities are trying very hard to stop any radiation leak.
