About two million people in the capital were without electricity and phone lines were down. Officials also warned residents not to smoke on the streets and not use mobile phones as gas mains could have been ruptured. President Peña Nieto said an emergency had been declared for the affected areas and the military was being drafted in to help with the response. Mexico City is one of the most densely populated cities in the world, with more than 20 million people living in the metropolitan area.
The tremor occurred on the anniversary of another one that left thousands dead in 1985. Alfredo del Mazo Maza, governor of the State of Mexico, ordered all public transport to operate services for free so that people could travel home. US President Donald Trump tweeted: “God bless the people of Mexico City. We are with you and will be there for you.” Costa Rican President Luis Guillermo Solis, in New York for the UN General Assembly, expressed his solidarity with the Mexican people.
