Earth Day started with an earthquake.
A magnitude 3.7 earthquake centered near Windsor Hills and Baldwin Hills shook Southern California around 12:03 a.m. Wednesday morning, according to the United States Geological Survey. The earthquake was centered less than a mile south of View Park-Windsor Hills, the USGS said.
The temblor was widely felt across Southern California, with Los Angeles International Airport tweeting that it was felt at the airport, but LAX reported no damage. NBCLA viewers and followers from Santa Monica, West LA and West Hollywood, up to Koreatown and Burbank and east to Whittier and Bellflower, along with Torrance in the South Bay, reported feeling the jolt.
Local news from across Southern California
More than 15,000 people responded early Wednesday to the USGS's Did You Feel It website, reporting feeling the earthquake as far as Santa Barbara and Palmdale to the north, Victorville to the east and Encinitas and Escondido in San Diego County to the south.
The earthquake was likely on the Newport-Inglewood Fault, seismologist Dr. Lucy Jones tweeted. Although less well-known than California's San Andreas Fault, the notorious fault runs through some of Southern California's most populated areas, stretching from Los Angeles' Westside and along the Orange County coastline.
In 1933, the deadly Long Beach earthquake along the fault resulted in a dramatic change in the way Southern Californians thought about earthquakes and how buildings in the region were constructed. More than 100 people died in the 1933 quake.

The earthquakes were all deep, well below oil fields in the area, she added. The Earth Day earthquake was about 7.4 miles (11.9 km) in depth, the USGS said.
Los Angeles Mayor Eric Garcetti said the LA Fire Department had been activated to conduct its routine survey of the city to assess for any damage.
Basketball player Alex Caruso of the LA Lakers and model and host Chrissy Teigen from too many shows to list took to Twitter to comment on the quake, as did many other Angelenos.
There were no reports of damage.
