Since the 10th of October 108 earthquakes have been located, 7 of which were felt by the population. The maximum intensity was III-IV in the epicentral zone, due to a 4.3 magnitude (mbLg) earthquake originating from a depth of 38km, this was the largest earthquake that occurred in the previous 24 hours. Of the earthquakes located in this period, 14 are found at depths greater than 30 km, and the rest of the hypocenters are located at a shallower depth, around 12 km. The column height measured at 6:30 UTC is 4,000 m, increasing 500 m in one day.
