“A big boom!” » This Thursday, November 21, 2024, early in the afternoon, several detonations were heard throughout the Pyrénées-Orientales department. These muffled noises caused the windows to vibrate and frighten the animals. But what could it possibly be?

What you need to knowUpdated 1h14 ago

Mysterious detonations were heard between 2 p.m. and 2:30 p.m. this Thursday, November 21 in a large part of the Roussillon plain and the Pyrénées-Orientales.

It is neither an earthquake nor the quarry blast recorded at 1:30 p.m. north of Perpignan, according to the BCSF-Rennass institute. It is also not a fighter plane, according to the Air Force.

At the end of our investigation, the mystery remains unsolved. The origin of these noises heard remains unknown.

The trail of a “mini-earthquake” ruled out

On social networks, the news spread like wildfire, between 2 p.m. and 2:30 p.m. Several hypotheses are put forward. Quickly, the idea that a mini-earthquake in itself at the origin takes precedence over the others.

It all starts from an observation by the French Central and Seismological Bureau – National Seismic Monitoring Network (BCSF-Rénass). At 1:32 p.m., an event of magnitude 2,0 is reported automatically

The first report from BCSF-Rénass suggested that a magnitude 2.0 earthquake had struck the Roussillon plain. The first report from BCSF-Rénass suggested that a magnitude 2.0 earthquake had struck the Roussillon plain.

south of Perpignan. However, according to several witnesses, the detonations of this Thursday took place several tens of minutes after the supposed earthquake. Curious.

After study by an analyst, the event was indeed a career shot in Baixas (Pyrénées-Orientales). After study by an analyst, the event was indeed a career shot in Baixas (Pyrénées-Orientales).

. The magnitude was also revised downwards (1.5 MLv).

: an automatically reported event has not yet been verified by BCSF-Rénass. It is therefore important to wait for an analyst to observe the phenomenon to definitively validate it.

The Air Force has nothing to do with it Could this career shot, of which there are around ten per day in , be the origin of these noises? “This has nothing to do with the detonation noise that you mention,” explains the BCSF-Rénass side.But then, where can they come from? On Facebook, other Internet users assure that this sound disturbance is linked to the

passage of fighter planes

. Here again, the hypothesis holds: when a military aircraft passes the sound barrier, the noise can be very violent. Contacted, the Air and Space Force (AAE) assures that it has nothing to do with it.

No fighter plane from the Air and Space Force (AAE), among those likely to operate in the area (from the and Mont-de-Marsan air bases), is at the origin of the noises described. Operational permanence (sky police), which can sometimes cause our planes to go supersonic, has not been triggered either. No major AAE exercise was also planned in this area during this time slot. Air and Space Force Among the other theses put forward by the Catalans: dismantling of wind turbines near Fitou (Aude). Although the operation probably caused a lot of noise locally, it is doubtful whether it could be the cause of a noise heard until Elneor even

according to the various testimonies that we were able to consult.

For now, and although it is frustrating, these detonations remain a mystery. We will be sure to let you know if we end up finding the end of this story.
