Following the magnitude 5.0 main quake, whose epicentre was in Alhendín overnight from Friday to Saturday, Granada province experienced a series of further tremors overnight into Sunday. The National Geographic Institute (Instituto Geográfico Nacional, IGN) has recorded around 20 seismic events since midnight, with epicentres in Ogíjares, Armilla, Gójar, La Zubia, Churriana de la Vega and Alhendín. Magnitudes were mostly between 1.5 and 3.1, and the hypocentres were shallow. This explains why around half of the earthquakes were felt by residents. The strongest, aftershockswith a magnitude of 3.1, occurred at 4.40 am near Armilla at a depth of around seven kilometres. Activity was concentrated on the southern flank of the Vega de Granada.
Official situation assessment: The service 112 Andalucía reported numerous calls from Armilla and the neighbouring towns of Las Gabias, La Zubia and Ogíjares. According to current information, there are no injuries; no specific reports of damage have been received. The relevant authorities advise people to follow official updates and observe standard safety measures during aftershocks.
Expert assessment: Seismological assessments suggest that this is a sequence of a main quake followed by aftershocks. Such sequences are characterised by one clearly strongest event, followed by tremors that are mostly weaker. Experts generally expect their frequency and intensity to decrease over time. At the same time, further aftershocks that can be felt may occur over the coming hours or days. This assessment differs from the earthquake swarms that affected mainly the northern part of the Vega de Granada for months in 2021.
Implications and next steps: Municipalities and the regional authorities are inspecting infrastructure and vulnerable buildings, logging reports and updating safety advice. Priorities include visual checks of buildings at heightened risk and ensuring residents have reliable information. The Junta de Andalucía is coordinating measures with local authorities and the IGN; adjustments will be made according to seismic activity. Forecasts of the timing and strength of possible further tremors are inherently uncertain and are based on ongoing monitoring data.
