A bright meteor that briefly swept across the sky over parts of the US Midwest and Canada on Tuesday, caused a powerful explosion that rattled homes and onlookers, weather and geology agencies confirmed.
The US National Weather Service (NWS) said the meteor was seen across the region in places such as Ohio, Michigan and Ontario at about 8pm local time.
It registered a 2.0 magnitude earthquake about 7km east of Saint Clair Shores in Eastern Michigan, the United States Geological Survey said on its website.

The meteor sighting lit up social media with people posting videos and reactions.
"I can't believe there was a Meteor! It shook our house and made a large bang! We thought someone hit our house," Twitter user Jennifer Wilson said in a post.
Others had more ominous thoughts.
"I thought for sure I was either seeing the alien invasion or the apocalypse. It's awesome in retrospect, freaky ... in real time," said a Twitter user who goes by the name Crash.
After curious residents took to social media to share videos of the incredible sky, the NWS took some time to evaluate what the star-gazers had seen.
It later confirmed it was not a meteorological event, but more likely a meteor.

"The NWS can confirm the flash and boom was NOT thunder or lightning, but instead a likely meteor," the NWS in Detroit said on Twitter.

The American Meteor Society's reported the meteor was visible in six US states as well as in Canada.
Despite the NWS confirmation of a tremor, researchers believe the meteor did not actually cause an earthquake.
William Yeck, a research geophysicist at the United States Geological Survey's National Earthquake Information Center in Colorado, told the ABC meteors don't actually cause earthquakes to rupture along a fault.
"While the event was reported as a magnitude 2, the magnitude scale is used to estimate the size of earthquakes and therefore is not an accurate representation of the observations from a meteor," Mr Yeck told said.
He added the seismic waves observed from these events are usually generated by sound waves in the atmosphere, rather than impact.
Researchers are continuing to investigate the event.
