25-01-2016 : Information on the Al Hoceima earthquake of 25/01/2016 at 04h22 UT
An earthquake of magnitude 6.4 was detected and located on 25 January 2016 at 04h22 UT (05h22 Spanish and French local time). Its epicentre was located approximately 50 km north of Al Hoceima (Morocco), a region affected by earthquakes of similar magnitude in 1994 and 2004.
