Alboran registers 2,300 earthquakes in just five months after intense August
It has peaked with a 5.1 earthquake on August 28
A seismic series with epicenters in the southern environment of the Alboran Sea, which has left earthquakes that have been felt in Melilla but also in points of Granada, Malaga or Almería, has registered, from the beginning of April 2021 until this September 3 , a total of 2,355 earthquakes, of which 18 have been greater than or equal to 4 degrees, and 129 have been felt by the population, reaching its maximum with an earthquake of 5.1 on August 28, the month in which tectonic activity has increased in the area.
This has been stated by the National Seismic Network in a report from the National Geographic Institute (IGN) updated this Friday. The beginning of the series is placed by experts on April 17, with an earthquake of magnitude 3.9. These are mostly shallow earthquakes, with a depth of less than 20 kilometers and magnitudes less than between 2.5 and 3. Of the 18 equal or more than 4, most have been "felt with a maximum intensity of III in Melilla" . The one of August 28 was noticed "with maximum intensity of IV" also in numerous towns on the coast of Malaga, Granada and Almería.
That day at the end of August, more than ten earthquakes were detected until late afternoon, the first and largest of them with a magnitude of 4.9 degrees on the Richter scale, now 5.1 after a change in the measurement. The day after, the largest of the recorded earthquakes reached a magnitude of 3.2 degrees, according to the data that were provided on the IGN website.
Sources consulted by Europa Press in the National Seismic Network explained that many of them are smaller aftershocks than the one registered on August 28, which can continue to last for a month or more in this fault zone whose activity "will continue for a while. "after an August with increased frequency and a slight increase in magnitude in some of these earthquakes.
Immediately below in magnitude that of this past Saturday, they would be the one registered on June 19, of 4.7 degrees, and on July 30, of 4.5. In the southern area of Alboran, it is expected that earthquakes of different magnitudes will continue to be recorded, having been one of 6.3 degrees in 2016, with the particularity that this series has of having its origin in the sea, and therefore " away from the population ". The distance leads to "attenuate seismic waves," explained from the National Seismic Network.
The IGN is a General Directorate of the Ministry of Transport, Mobility and Urban Agenda. It exercises, through the National Seismic Network, the functions of planning and management of detection and communication systems to the institutions of the seismic movements that occurred in the national territory and their possible effects on the coasts, as well as carrying out works and studies on seismicity and the coordination of seismic resistant regulations.
If an earthquake is perceived, the experts call to try to remain calm and follow the advice of 112, which has warned, in relation to the seismic series of Granada, that the ideal thing is "always stay in the place where you are until the shaking ends and do not enter or leave the place "where one is.
Experts from the University of Granada (UGR) recommend on the web that, in a situation like this inside a building, look for "strong structures" or place oneself "under a table or bed (or next to them)" or a sofa or counter, "between two rows of seats (theaters and cinemas), in a corner and above all" protecting the head. It is necessary to stay "away from exterior walls, windows, glassware and showcases, also from heavy furniture or objects that can fall". It is not recommended to use the elevator and never run "headlong to the exit".
