Every so often there will be a horrific news story where a natural gas leak causes a huge explosion, either in a house or a chain of houses. One of the most devastating was the Merrimack Valley gas incident:

On September 13, 2018, excessive pressure in natural gas lines owned by Columbia Gas of Massachusetts caused a series of explosions and fires to occur in as many as 40 homes, with over 80 individual fires, in the Merrimack Valley, Massachusetts, towns of Lawrence, Andover, and North Andover. One person was killed and 30,000 were forced to evacuate their homes immediately.

But the more common scenario is that there is a gas leak in a house, and the leak fills a room or a basement with gas, and then a spark ignites it and creates an explosion. Here is what these explosions look like:

In this case, the house explodes, then there is a fire, and the fire sets off ammunition stored in the house

The Merrimack Valley (Andover MA) gas explosion was horrible because it destroyed so many houses

Sometimes it is a gas main that leaks, and these leaks can cause tremendous fires

In 1927 Pittsburg experienced an enormous gas explosion – one of the most famous still in the United States
