Which active faults threaten Mexico City?

The fault systems associated with Mexico City are named in the hub header and drawn on the map alongside recorded seismicity. Proximity alone does not rank hazard: rupture length, slip rate and the time elapsed since the last event all matter, so the page shows the traces and the observed activity rather than a single ranking.

Who is the emergency service for Mexico City?

The civil protection agency responsible for Mexico City, with its emergency number, is shown on this page. Call it for any life-threatening situation; for official damage reports and aftershock bulletins, follow the national seismological agency listed among our data sources.

Mexico City

The city rests on the drained lakebed of Texcoco, whose soft clays amplify long-period waves several-fold; the 1985 earthquake nucleated 350 km away on the Cocos interface and still levelled buildings in the centre.
