The earthquake caused all of Mexico City to tremble, prompting people to evacuate after the early warning system was triggered.[7] It also generated a tsunami with waves 1.75 metres (5 ft 9 in) above tide level;[8] and tsunami alerts were issued for surrounding areas.[9] Mexico's president called it the strongest earthquake recorded in the country in a century.[10] It was also the second strongest recorded in the country's history, behind the magnitude 8.6 earthquake in 1787,[11] the largest recorded globally in 2017 and the largest earthquake worldwide since the 2015 illapel earthquake.[12]
