The most severe shaking occurred on August 18, when a magnitude 4.8 earthquake struck at 10:37 local time. This event was preceded by another magnitude 4.8 tremor on the night of August 14. Following the August 18 event, three additional strong aftershocks occurred within a two-hour window, with magnitudes of 3.9, 4.2, and 4.0. The cumulative impact of this activity has resulted in the evacuation of approximately 600 residents from six apartment blocks in Las Gabias, containing 371 dwellings, after damage was identified. Additionally, all 77 residents of the Reina Sofía Psychopedagogical Center were relocated to other care facilities following the discovery of structural damage.
Emergency coordination centers recorded 5,562 calls related to the seismic episode by 12:30 local time on August 19. Reported incidents included cracks in walls, falling building materials, broken water pipes, and individuals trapped in elevators. Medical services attended to 14 people during the stronger activity on August 18, with three sustaining minor injuries, including a 13-year-old girl struck by a falling brick. The majority of medical cases involved anxiety, dizziness, and minor trauma. Of the 621 earthquakes recorded between August 14 and August 19, most were below magnitude 2, while 10 reached magnitude 3 or greater. Forty-two of the tremors were felt by the local population.
Technical teams conducted inspections on 580 buildings and properties across the affected area by August 19. The assessments classified 459 structures as green, indicating no damage; 105 as yellow, indicating minor damage; and 14 as red, requiring safety measures before normal occupancy could resume. The seismic activity also disrupted public services, with several facilities temporarily closed and transport links affected. The Alhambra, a major cultural site in Granada, activated its earthquake procedures, evacuating parts of the complex and closing to visitors for specialist inspections. Officials stated that no significant structural damage had been identified at the Alhambra, though minor damage to decorative plasterwork was recorded. The site largely returned to normal operation by August 20, although visitor routes through the Nasrid Palaces were modified to facilitate rapid evacuation if necessary, and the Alcazaba remained closed for continued inspections.
Geological data indicates that the sequence is concentrated in a shallow zone, which explains the high intensity of the shaking despite the moderate magnitudes. The repeated tremors over the past week have created an environment of heightened alertness, with authorities continuing to monitor the situation closely. The primary focus remains on the structural integrity of the 14 buildings classified as red and the ongoing monitoring of the remaining yellow-classified structures. No fatalities have been reported in connection with this seismic sequence.
