Between 14 and 18 August 2026, the Instituto Geográfico Nacional (IGN) recorded a series of earthquakes in and around the cities of Alhendín and Gójar The strongest shock, on 15 August, was initially reported at magnitude 5.0 mbLg and later revised to 4.8 in the catalogue; further clearly felt tremors followed on 18 August. The sequence of the main shock and numerous aftershocks was widely felt across the Granada metropolitan area and caused minor property damage in some places. The Junta de Andalucía activated the Plan de Emergencia ante el Riesgo Sísmico (Situación 1).
Experts stress the need to distinguish clearly between measured data and statements about risk. The recorded magnitudes, times and epicentres are confirmed; statements about a possible “major earthquake” are assessments subject to uncertainty. Juan Vicente Cantavella, head of the Red Sísmica Nacional, points to historical events on the Iberian Peninsula that reached magnitudes above 6 and argues for better preparedness among the public and in infrastructure. There is no short-term forecasting capability. Belén Benito, Professor of Seismic Risk at the Universidad Politécnica de Madrid, warns of a risk that has long been underestimated; her phrase “estamos en tiempo de descuento” is a call for preparedness—not a prediction of an imminent event.
From the perspective of science and civil protection, several steps are a priority: updating seismic hazard maps on the basis of the latest measurement series; stricter requirements for strengthening existing buildings during renovations; systematically incorporating worst-case scenarios into civil protection plans; and ongoing information campaigns for residents in exposed areas. In their communications, the authorities distinguish between the IGN’s documented measurement data and the political and planning conclusions drawn from them. Geological work is also under way to improve the modelling of active fault zones in the Betic Cordillera. Despite dense monitoring networks, it remains impossible to predict the exact timing and magnitude of individual earthquakes.
As of the editorial deadline, the situation is as follows: according to the authorities, activity had slowed noticeably by 21 August; tremors recorded overnight were noticed by the public only in some cases. The Instituto Geográfico Nacional is continually updating its catalogues, while the Junta de Andalucía is maintaining its state of readiness under the current emergency plan. Analysis of the sequence and any adjustments to maps and regulations are being carried out through a regulated process subject to expert review.
