A magnitude-4.1 earthquake that was reported on the U.S. Geological Survey website shortly after 11 a.m. near the Salton Sea has been ruled a "bogus quake" and unrelated to a much larger incident in Mexico, a USGS spokesperson said Tuesday.

The local quake appeared on the USGS website about 11:07 a.m. and was removed minutes later. About the same time, 115 miles east from Acapulco, Mexico, a magnitude-7.6 quake struck.

The USGS confirmed the two incidents are unrelated.

At least 60 homes near the epicenter collapsed, the Associated Press reported.

About 40 passengers were stranded for a short time on the Mexico City airport air train, but later released. The airport closed for a time but officials said there was no runway damage and they resumed operations.

At Los Angeles International Airport, no flight delays related to the disaster were reported.

The quake was felt strongly in southern Oaxaca state next to the epicenter in Guerrero.

"It was very strong, but we didn't see anything fall," said Irma Ortiz, who runs a guesthouse in Oaxaca. She said their telephones are down, and that the quake shook them side-to-side.
