Overview
- A magnitude 5.6 earthquake near Pinotepa Nacional, Oaxaca, at 9:19 a.m. Monday set off Mexico City’s public sirens and led to building evacuations.
- Authorities reported no injuries or structural damage after helicopter overflights, Metro checks, and safety inspections across the capital.
- Cellphone alerts did not go out because the federal Cell Broadcast platform was in rapid maintenance, officials said.
- The city’s C5 said more than 98% of 13,992 loudspeakers worked and logged 25 cases tied mostly to falls and anxiety.
- Officials will proceed with a nationwide drill at 11 a.m. Wednesday to test loudspeakers, TV and radio warnings, and Cell Broadcast, which sends government alerts straight to phones.
