The article here on the La Voz de Almería website has details of a new fault line found in the Alborán sea not too far away from Almerimar. According to the article it may have been responsible for a number of earthquakes in the area in the last few years.

A new fault in Alboran can cause "relatively" strong earthquakes

The discovered fracture would be responsible for the 6.3-degree earthquake of January 2016

An international team of scientists led by the Higher Council for Scientific Research has identified a new fault in the Alboran Sea. According to the investigation, the fracture produces little deformation in the seabed, but "relatively high magnitude earthquakes", such as the magnitude 6.3 on the Richter scale that affected Melilla and several areas of Almeria in January 2016, reports Europa Press

According to the main author of the work, Jesús Galindo-Zaldívar, researcher at the Andalusian Institute of Earth Sciences (mixed center of the CSIC and the University of Granada), the scientists set out to map the seabed after the earthquake of January 2016 , which caused significant damage in Melilla and other Moroccan cities, as well as studying the seismicity of the area, since this did not correspond to the position of the Al-Idrisi fault, which affects the central and southern area of ​​the Alboran Sea and the only one that was known until this moment.

Initial state "Our research confirms that the initial seismicity is associated with a failure in an initial state of formation, which has a Northeast-Southwest direction and produces little deformation on the seabed," adds the scientist Galindo-Zaldívar.

Among the conclusions of the study, which appears in the journal 'Tectonics', the expert also highlights that the formation of the Gibraltar arch between Iberia and Africa continues with the migration of the tectonic deformation towards the West. As for the seismicity, it also extends to the North, affecting the Campo de Dalias region, in the west of Almería.

As he explains, "the existence of submarine landslides and recent minor faults in the epicenter zone confirm the tectonic activity of this incipient fault zone with high seismic risk". According to Jesús Galindo-Zaldívar, the work lays the foundations to focus future geological, seismic and geodetic studies in this main deformation zone, from Alhucemas to Campo de Dalias, which crosses the Alboran Sea.

The January 2016 earthquake of 6.3 was the largest, but not the only one. In December 2015, a seismic series began that caused thousands of tremors, so many that by February 24, 1,600 earthquakes had already been registered by the National Geographic Institute.
