- The earthquake has raised concerns about the city's seismic resilience and the need for improved disaster preparedness and response.
Understanding the Science Behind the Earthquake
Earthquakes are complex natural disasters that are not yet fully understood by scientists. However, research suggests that the earthquake that struck Lisbon was likely caused by a combination of tectonic plate movement and geological fault lines. The Iberian Peninsula, where Portugal is located, is situated on the boundary between the Eurasian and African tectonic plates, making it a seismically active region. Seismologists believe that the quake was triggered by a sudden release of energy as the plates moved past each other, causing the ground to shake violently.
Tectonic Plate Movement and Geological Fault Lines
The movement of tectonic plates is a gradual process that occurs over millions of years. As the plates move, they can become stuck at their boundaries, causing stress to build up. When the stress becomes too great, the plates will suddenly move, releasing the stored energy as seismic waves. Geological fault lines are areas where the plates have moved in the past, creating zones of weakness in the Earth’s crust. These fault lines can be reactivated by subsequent plate movement, leading to earthquakes.
