LISBON – Two noticeable earthquakes struck Portugal’s capital early Thursday afternoon, briefly unsettling residents and highlighting the geological vulnerability of one of Europe’s historic coastal cities. According to the European-Mediterranean Seismological Centre (EMSC) and the Portuguese Institute for Sea and Atmosphere (IPMA), the tremors measured just above magnitude four. Authorities reported no injuries or property damage, but officials urged citizens to remain calm.
The quakes occurred within minutes of each other around 13:00 CET. The EMSC estimated the first at magnitude 4.2, while IPMA calculated a slightly lower 4.1. Across several districts, residents reported swaying lights, vibrating windows and temporary evacuations from office buildings and apartment blocks. Public transportation and airport operations continued without interruption.
Seismologists emphasize that Lisbon’s location makes such events expected rather than exceptional. The city sits near the complex boundary between the Eurasian and African tectonic plates, an active zone beneath the Atlantic Ocean capable of generating both moderate tremors and rare but catastrophic earthquakes. While Thursday’s shocks were considered minor, they serve as a reminder of the region’s persistent geological tension.
Lisbon’s history is inseparable from seismic disaster. The catastrophic earthquake of 1755 destroyed most of the city and triggered a massive tsunami and fires, killing an estimated 30,000 to 40,000 people. The tragedy reshaped European thinking about urban planning, disaster preparedness and even philosophy during the Enlightenment. Another powerful quake in 1969, with a magnitude of 7.9, caused further casualties and reinforced the country’s investment in monitoring systems and building regulations.
Today Portugal maintains a modern seismic monitoring network and emergency protocols designed to react quickly in case of stronger activity. After Thursday’s tremors, civil protection authorities kept emergency services on standby but did not order evacuations.

Though relatively mild, the tremors underline a simple reality: in Lisbon, seismic risk remains part of daily life, and preparedness is not a temporary policy but a permanent necessity.
