A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas , methane , propane , butane .
For an explosion to occur, there must be a rapid, forceful expansion of matter. There are numerous ways this can happen, both naturally and artificially, such as volcanic eruptions, or two objects striking each other at very high speeds, as in an impact event. Explosive volcanic eruptions occur when magma rises from below, it has dissolved gas ...

This can happen in rooms where the fire subsided because of lack of oxygen. The ignition source can be a smouldering object, or the stirring up of embers by the air track. Such an event is known as backdraft. A delayed flashover occurs when the colder gray smoke cloud ignites after congregating outside of its room of origin.
The main mechanism of detonation propagation is of a powerful pressure wave that compresses the unburnt gas ahead of the wave to a temperature above the autoignition temperature. In technical terms, the reaction zone (chemical combustion) is a self-driven shock wave where the reaction zone and the shock are coincident, and the chemical reaction ...
SANHE, China (Reuters) -A suspected gas leak caused a blast at a restaurant in China's northern province of Hebei that ripped facades from buildings, damaged cars and scattered debris to kill two ...
A vehicle loaded with gas exploded and set off an inferno that burned homes and warehouses in Kenya's capital, killing at least three people and injuring more than 270, officials said Friday, with ...
