In Mexico City, about 500km away, “light to moderate” shaking was reported, capable of causing “very light” damage, especially to vulnerable structures. There were no known casualties or damage in Mexico City, according to the city’s mayor, Claudia Sheinbaum. Local news channels reported that firefighters closed some buildings in Mexico City to the public due to collapse concerns. One person died after a fence fell at a shopping center in Manzanillo in the western state of Colima, President Lopez Obrador said on social media, citing Jose Rafael Ojeda Duran, the secretary of the Navy. Mexico’s Civil Protection Coordinator Laura Velazquez also confirmed the death in a press conference Monday afternoon. The magnitude of the earthquake was initially reported by the US Geological Survey (USGS) as 7.6. Mexico’s national seismological agency later updated the magnitude to 7.7 at a press conference on Monday. According to the USGS, the earthquake occurred about 37 kilometers southeast of the city of Aquila, with a depth of about 15.1 kilometers. Immediately after the quake, the Pacific Tsunami Warning Center said waves of up to 3 meters could hit Mexico. Initial tsunami waves have likely already occurred in coastal locations such as Manzanillo and Acapulco, and could also hit tourist hotspot Puerto Vallarta. Tsunami waves of less than 0.3 meters could also occur along the Pacific coasts of Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Nicaragua, Panama and Peru, according to the organization. The news came on the fifth anniversary of the 2017 earthquake that killed 216 people in Mexico City. The epicenter of this 7.1-magnitude earthquake was 2.8 miles (4.5 km) east-northeast of San Juan Ramboso and 34.1 miles (55 km) south-southwest of the city of Puebla in Puebla state, it said then the USGS.
