How many explosions were in Chernobyl?

The Chernobyl disaster involved a series of explosions, with the most significant being two main explosions that occurred on April 26, 1986, in Reactor No. 4 of the Chernobyl Nuclear Power Plant. The first explosion was a steam explosion caused by a sudden power surge, followed by a second, more powerful explosion due to the release of hydrogen gas. These explosions resulted in the catastrophic release of radioactive materials into the environment.
