On September 21, 2024, a magnitude 2.9 earthquake shook the Lourdes region in the Hautes-Pyrénées. This seismic event, although moderate, caused some concern among residents and highlighted the seismic vulnerability of this mountainous region.
Earthquake Details
The earthquake occurred at 7:01 p.m., with an epicenter located near Lourdes, at a depth of 10 km below the surface. The tremors were felt mainly in the neighboring municipalities, including Agos, Argelès-Gazost, Bagnères-de-Bigorre, Juillan, Tarbes, and Aureilhan. Although the intensity of the earthquake is considered low, residents reported feeling notable vibrations.
Residents’ Reactions
Residents’ testimonies vary depending on their proximity to the epicenter. For example, in Argelès-Gazost, Fabienne described the tremors as “strong and brief”, while in Bagnères-de-Bigorre, Nathalie also felt the tremors1. These reactions show that even a small earthquake can cause panic and are a reminder of the importance of disaster preparedness.
Seismic Context of the Hautes-Pyrénées
The Hautes-Pyrénées is a region known for its regular seismic activity. Although most earthquakes are small, the region remains vulnerable due to its complex geology and proximity to active faults1. Local authorities and seismologists constantly monitor seismic activity to prevent and minimize risks to the population.
Prevention and Safety Measures
In response to this earthquake, the Hautes-Pyrénées Prefecture reminded residents of the safety measures to follow in the event of aftershocks2:
● Inside a building:
○ Take shelter near a load-bearing wall or under sturdy furniture.
○ Stay away from windows to avoid broken glass.
○ If you are on the ground floor and near the exit, leave the building and move away.
● Outside a building:
○ Do not stay near electrical wires or anything that could collapse (bridges, roofs, chimneys).
● By car:
○ Stop as far away from any building as possible and wait for the shaking to stop.
These tips are intended to minimize the risk of injury and material damage in the event of an earthquake.
Importance of Preparedness
This event highlights the importance of preparedness and vigilance in earthquake-prone regions. Lourdes is home to a Maison de la Seismicité “Epicentre”, dedicated to education, prevention and information on seismic risk2. This institution plays a crucial role in raising awareness of seismic hazards and promoting safety practices.
The Lourdes earthquake of September 21, 2024, although moderate, highlighted the need for continued preparedness and increased vigilance in the face of seismic risks. Local authorities, seismologists and educational institutions work together to ensure the safety and resilience of communities in the face of these natural events.
