Two separate small earthquakes have rattled buildings and scared residents in the US states of California and Michigan.
One earthquake hit Los Angeles, California on Sunday. It was a 3.9-magnitude quake, according to the US Geological Survey (USGS).
The tremor shook buildings and woke up residents in the early morning hours, local media said.
Although the quake was classified as light by the USGS, it was felt over a wide area of the Los Angeles basin.
According to the Los Angeles Fire Department, which briefly went into “earthquake mode,” there were no reports that the tremor caused damage.
The alert was lifted soon after helicopters from the fire department searched hundreds of square miles in areas that were impacted by the quake.
The epicenter of the quake was just a mile northwest of the Park-Windsor Hills neighborhood north of the cities of Inglewood and Culver City.
The tremor was the second one in less than a month in the same area along the major Newport-Inglewood fault line.

On Saturday, a rare earthquake rattled the state of Michigan over a thousand miles away from California to the east.
The earthquake measured 4.2 on the Richter scale and shook mainly the western part of the “Great Lakes State.”
The quake caught people by surprise, but no damage was reported.
"The whole building was moving. You could see the walls shaking and things on shelves were shaking. Some things fell off of the shelves," Cindy Bristol told local media while describing the quake.
This was the second largest earthquake in Michigan’s recorded history.
In 1947, a tremor measuring 4.6 on the Richter scale caused moderate damage to buildings in Michigan.
