Minor earthquake hits southern France
An earthquake of magnitude 3.9 has been recorded in the Pyr茅n茅es-Atlantiques in southern France, hitting the department in the early hours of yesterday morning (Saturday November 2).
6h22, with the epicentre thought to be the commune of Oloron-Sainte-Marie in Barcus, around 35 kilometres from the nearest town of Pau, in the region of Nouvelle-Aquitaine.
The quake registered 3.9 on the Richter scale, according to early reports from the national seismic surveillance network, R茅Nass (which is based in Strasbourg, in Grand Est).
This compares to the lesser 3.2 magnitude registered by the seismic activity recorders in the Pyr茅n茅es.
The quake was around nine kilometers deep, .
No serious damage has been reported, and : 鈥淟ocal firefighters did not report any interventions.鈥�
The Richter scale, developed in 1935 by Charles Richter, measures the strength of an earthquake.
The scale is logarithmic, meaning that an increase of one unit actually signals an earthquake 10 times鈥� as powerful - so a quake measuring 3 on the scale is 10 times鈥� as strong as a quake measuring 2.
According to , quakes are considered to be minor from 3.0 to 3.9 on the scale, and are often felt by people nearby, but hardly ever cause any damage.
Quakes registering 4-4.9 may cause objects inside houses to move, but usually no further damage; those registering 5-5.9 may cause damage to unstable buildings; and those registering 6-6.9 may cause more serious effects.
Quakes registering from 7-9.9 will cause severe, destructive damage, and are only felt every 1-20 years.
No earthquake has yet reached the 鈥渢op magnitude鈥� of 10.0; but the strongest ever recorded was the Great Chilean Earthquake in Chile, in 1960, which was recorded at 9.5 on the Richter scale, and killed more than 6,000 people.
