Low Magnitude Earthquake Strikes Lisbon: What You Need to Know!

Lisbon Earthquake Details

A low magnitude earthquake struck the Lisbon area on Monday afternoon, according to Filipe Rosas, director of the Dom Luiz Institute at the University of Lisbon. Despite its relatively low magnitude, the shallow depth and proximity to populated areas raised concern.

The earthquake had a magnitude of 4.6 and occurred at a depth of seven kilometers. The IPMA reported the epicenter was located 14 kilometers west-southwest of Seixal, while the USGS noted it was on land, near Charneca da Caparica.

Unusual Seismic Activity

This region has a history of seismic activity, but the magnitude of this event was higher than usual. João Fontiela, a seismology expert, stated that such a magnitude of 4.6 is not common, as normal readings are typically below 2.0.

Interestingly, just before this earthquake, a magnitude 1.6 quake was recorded nearby on Sunday night, leading to speculation about whether these events are connected. Fontiela emphasized that while these earthquakes release energy, their theoretical seismic risk remains low.

Potential Risks and Impacts

Even though these quakes release less energy, their destructive potential can be significant due to their shallow depth and proximity to urban areas. Rosas indicated that the tectonic system may have released some tensions, suggesting that if no further seismic activity occurs, it’s a sign that the region is stable for now.

Overall, while the earthquake was of low magnitude, its shallow depth and location near populated areas warrant attention and preparedness in the community.
