A moderate earthquake with a preliminary magnitude of 5.2 struck near San Marcos, Guerrero, Mexico, on Saturday, June 13, 2026. The National Seismological Service reported the event, which occurred at 12:20 PM local time.

The epicenter was pinpointed 26 kilometers southwest of San Marcos, Guerrero, at a shallow depth of 10 kilometers. The tremor was felt in various parts of the region.

In Mexico City, some residents reported receiving seismic alerts on their cell phones. However, the Secretariat of Integral Risk Management and Civil Protection (SGIRPC) clarified that the seismic alert system was not officially triggered. The perceived shaking in some areas of the capital was described as very light.

The SGIRPC explained that the alert is activated only when the initial estimation of energy released in the first seconds of a quake surpasses specific pre-established thresholds. In this instance, the energy detected did not meet the criteria for activating the broader seismic alert system, despite some localized phone notifications.

Safety protocols were initiated following the event, and authorities confirmed that the earthquake did not necessitate the activation of the official seismic alert for the city. The event occurred amidst the ongoing 2026 World Cup festivities, which are being hosted in part by Mexico.
