The National Weather Service says an exploding meteor is likely the cause of a loud boom and shaking ground reported on New Year’s Day across portions of suburban Pittsburgh.

Allegheny County officials reported in a Twitter post Saturday that county 911 officials had received reports from South Hills and other areas about the disturbance.

County officials said they had confirmed that there was no seismic activity and no thunder and lightning.

The Tribune-Review reports that National Weather Service meteorologist Shannon Hefferan said satellite data recorded a flash over Washington County shortly before 11:30 a.m. Saturday.

The weather service theorizes that it was caused by a meteor “falling through the atmosphere.”

Hefferan said a similar event was recorded on Sept. 17 in Hardy County, West Virginia.

Residents reported hearing a loud noise and feeling their homes shaking and rattling.
