A powerful natural disaster has shaken buildings and caused panic in six Mexican states, killing at least six people.
President Andres Manuel Lopez Obrador said that so far ports, airports, hydroelectric plants, all are in good condition.
Reuters witnesses in Mexico Metropolis observed no initial indications of injuries or damage.
Two men and a woman were among the dead in separate incidents as a result of damage to roofs and walls.
Buildings also shook in Mexico City, 700km (435 miles) from the epicentre. Seismic alarms sounded mid-morning with enough warning for residents to exit buildings.
Mexico City is particularly vulnerable to earthquakes, as its soft and wet soil is shaken and liquefied, in which dust becomes dense liquid when sufficiently entangled.
"Buildings were shaking but I tried not to look at them because it causes you to panic", said Juan Sosa Flores, 61, who was speaking over the wail of ambulance sirens on Paseo de la Reforma, a main street in Mexico City's financial district.

Hours after the natural disaster, several groups of people remained in the streets and sidewalks fearing the aftershocks.
Many were not wearing masks despite past appeals from municipal officials for them to do so as a way to curb the spread of the new coronavirus.
"It was really intense, really strong", she said. "It's terrible, you're here and you don't know what to do", she said.
The US Pacific Tsunami warning centre initially said hazardous waves as high as three meters could strike anywhere within 1,000 kilometres of the quake's epicentre, affecting the Pacific coast of Mexico and Central and South America.
In Huatulco, a laid-back beach destination known for surfing and small protected coves, the quake knocked goods off shelves and some rubble from buildings.
Eunice Pineda, a 26-year-old teacher in Juchitan, said the quake "was two minutes of torture", as she feared her house would collapse.
González said there was some visible broken glass and mirrors, but no major damage. Staff were waiting for the aftershocks to dissipate before fully evaluating the property.
The quake also caused slight damage to four hospitals and a clinic, as well as to churches, markets and other buildings, authorities said.
A Reuters witness in the state's Pacific coast resort town of La Crucecita, which Mexican authorities said was the epicenter of the natural disaster, saw anxious residents standing outside their homes hours after the tremor as they feared deadly aftershocks.
