A magnitude 5.5 earthquake struck south of Lisbon early this morning, causing tremors that were felt in several regions of Spain and Morocco. The earthquake occurred at 6:11 am (Spanish mainland time) at a depth of 19 kilometres, according to the Spanish National Geographic Institute (IGN).
Residents in southern Spain, particularly in Huelva and Seville, reported feeling the quake, as did those in parts of Morocco. While the full impact of the earthquake is still being assessed, no immediate reports of significant damage or casualties have been confirmed.
Safety precautions during earthquakes
In light of this recent seismic activity, the IGN has issued reminders about the importance of knowing how to respond during an earthquake. The key advice is to stay calm and seek immediate shelter under sturdy furniture like tables or desks. If no such protection is available, covering one’s head and neck with arms and positioning oneself near an interior wall away from windows and objects that could fall is recommended.
For those outside during a quake, it’s crucial to move away from buildings, trees, and power lines to an open area. If you are driving, stop in a safe location, away from overpasses, bridges, and buildings, and remain in the vehicle until the shaking stops.
After an earthquake, it’s important to check for injuries and provide first aid if necessary. Inspect homes or buildings for structural damage and avoid using elevators. Stay informed through official channels and be prepared for aftershocks, which can continue for days or even weeks after the initial quake.
Lisbon’s seismic history: A reminder of past disasters
This recent earthquake serves as a reminder of Lisbon’s historic vulnerability to seismic events. On 1 November 1755, one of the most devastating earthquakes in European history struck Lisbon, estimated at a magnitude between 8.5 and 9.0. The disaster occurred on All Saints’ Day, triggering a massive tsunami and multiple fires that nearly obliterated the city.
The 1755 earthquake had a profound impact, with estimates of 10,000 to 100,000 lives lost. Iconic structures, including the Royal Palace and many churches, were destroyed. The disaster also affected coastal areas in Portugal, Spain, and North Africa.
In the aftermath, the Marquês de Pombal, then Prime Minister of Portugal, led the reconstruction of Lisbon, introducing pioneering earthquake-resistant building techniques and a new urban plan that influenced modern architecture and city planning.
