An earthquake of magnitude 6.3 struck the Alboran Sea off Melilla / Morocco, on January 25 at 4:22 UTC.

The epicenter is located 150 km east of the Strait of Gibraltar and a depth of 10 km.
This earthquake was preceded on January 21, at 1:47 p.m. local by a tremor of magnitude 5, and followed by no less than 36 replicas as I write this note. These earthquakes were felt in Morocco and Spain.

The earthquake occurred 50 km north of the epicenter of Al Hoceima earthqueke of February 24, 2004, and also magnitude 6.3; Twelve years ago, he caused the death of 630 victims.


The origin of earthquakes that hit this area is possibly linked to faults escarpments, which reach up to 5 meters in front of the coast of Al Hoceima. A 2014 study concluded to the need to consider regional vulnerabilities to determine the possibility and frequency of earthquakes caused in this area.
