A large explosion leveled a million-dollar home in northwest suburban Long Grove and damaged dozens of others within a half-mile radius.

“It’s by the grace of God that nobody got hurt,” said Countryside Fire Chief Jeff Steingart.

Firefighters were called to the home at Trenton Court and Wellington Drive in the Royal Melbourne subdivision around 10:40 p.m. Friday with reports of a fire.

The explosion happened before first responders arrived.

A husband and wife live in the home, but the husband wasn’t home at the time. The wife made it out before the blast.

The subdivision was evacuated while crews from multiple towns worked to get the situation under control.

Two people were treated on the scene for minor injuries.

The mess left behind from the explosion is reminiscent to what you would find after a tornado. It’s unclear how long the cleanup will take.

Several agencies are part of the investigation: North Shore Gas, Illinois Fire Marshal’s Office, Long Grove Police, Countryside Fire Protection District and the Bureau of Alcohol, Tobacco and Firearms.

The gas had to be shutoff to 30 nearby homes so that the line could be fixed.

A preliminary investigation has revealed that the explosion may have been caused by a natural gas leak, although further investigation is on-going.
