The Tremors That Keep Mexico City on Its Toes

Mexico City experiences frequent low-intensity earthquakes due to its location on geological faults. These tremors, known as microseisms, are caused by the movement of these faults, often triggered by larger seismic events.

The Tremors That Keep Mexico City on Its Toes
When your city is on a fault line, even the smallest tremor can feel like a big deal.

Mexico City, a sprawling metropolis built atop the remnants of ancient lakes, carries within its ground a geological secret that rumbles every now and then. Often imperceptible to most residents, these tremors—officially recorded as 137 microseisms between 2023 and 2024—are subtle reminders of the Earth’s ever-present tectonic dance.

With 52 such events already noted this year and 85 in 2023, Mexico’s capital quietly witnesses seismic activity regularly. Though many residents may remain oblivious, these microshakes have significant implications for a city already grappling with the challenges of subsidence, self-constructed buildings, and a history of devastating quakes.
