The sequence of earthquakes recorded in Granada since last Saturday, with one of 4.7 degrees of magnitude recorded this very morning, test a civil protection system in which the autonomous community directs the emergency, the municipalities provide the first response on the ground, and the State monitors seismic activity and provides support when the situation exceeds the autonomous resources.
A question that usually arises after each natural disaster is which Administration is responsible for managing it in Spain? The answer does not correspond to a single institution. Civil protection works as a tiered system in which municipalities, autonomous communities, and the State participate.
In the case of Granada, the Junta de Andalucía assumes the general direction of the emergency, while the municipalities manage immediate actions within their municipal terms.
The State, for its part, is responsible, through the National Geographic Institute (IGN), for detecting and analyzing earthquakes. It can also provide extraordinary means or assume direction if the Ministry of the Interior declares that there is a national interest emergency.
This distribution of responsibilities is what has been reactivated after the earthquake of this Tuesday, August 18, with epicenter northwest of Gójar and which has been followed by another movement of magnitude 4.0 and by several smaller earthquakes. The episode occurs three days after the earthquake of magnitude 5.0 initially located in the vicinity of Alhendín.
The Junta directs the seismic emergency in Andalusia
The main competence to manage a seismic emergency affecting one or several municipalities corresponds to the autonomous community, in the case of Granada, to the Junta de Andalucía. The community has a Seismic Risk Emergency Plan that establishes the chain of command, the available resources, and the actions that must be implemented.
After the earthquake last Saturday, the Junta elevated the plan to emergency phase, operational situation 1. This level means that the consequences can be controlled with the ordinary and extraordinary means available in Andalusia, without the need for the State to assume direction.
Thus, the Junta is responsible for activating and directing the autonomous plan in the face of seismic risk, coordinating the 112 service, health services, the autonomous police, firefighters, and resources from different administrations, gathering the advisory committee and establishing operational coordination centers, distributing available resources among the affected municipalities; ordering, when necessary, evacuations, confinements, or access restrictions; coordinating the inspection of essential infrastructures, such as hospitals, schools, roads, or transport networks; informing the population and establishing self-protection recommendations and requesting state resources when autonomous resources are insufficient.
The Emergency Plan for Seismic Risk in Andalusia includes a provincial or regional organization depending on the extent and severity of the episode.
What powers do municipalities have in the event of an earthquake
Although the Junta directs the autonomous device, municipalities are the first Administration that intervenes materially on the ground. Mayors maintain responsibility for municipal services and can activate their own emergency plans.
Among the municipal powers are activating the territorial plan or the municipal action plan in the face of seismic risk; mobilizing the Local Police, municipal firefighters, Civil Protection, and maintenance services; closing streets or evacuating buildings when there is an immediate risk; inspecting municipal buildings, homes, facades, cornices, and other potentially dangerous elements; providing temporary accommodation for evacuated people; removing debris and securing public spaces; providing information about damages and needs to the Junta's coordination center, as well as collaborating in the care of vulnerable people and in the restoration of basic services.
The mayor can take urgent measures within their municipality, but when the autonomous plan is activated, local resources are integrated into the coordination structure directed by the corresponding autonomous community.
Granada capital has a Municipal Action Plan for Seismic Risk, approved in 2016, which organizes the intervention of its services. After the latest movements, the Local Police has asked the population to avoid staying near facades and buildings due to the possible risk of collapses.
Who does what in the event of an earthquake
| Administration | Main responsibility | Actions |
|---|---|---|
| City Councils | First local response | Local Police, firefighters, evacuations, road closures, inspections, and assistance to residents |
| Andalusian Government | Regional direction and coordination | Activates the seismic plan, coordinates 112, distributes resources, and directs the emergency |
| State | Seismic monitoring, national coordination, and extraordinary support | IGN, Security Forces and Corps, UME, and state resources |
| Ministry of the Interior | Direction in emergencies of national interest | Can take command if the crisis exceeds the regional scope or affects national interest |
The State detects earthquakes and can provide resources
The National Geographic Institute, dependent on the State, is the body responsible for the detection, location, and calculation of seismic parameters. Its technicians determine the magnitude, epicenter, depth, and intensity with which each movement has been felt.
The IGN does not directly manage evacuations or emergency interventions. Its function is to provide the scientific information that allows Civil Protection and administrations to decide what measures to take.
The State can also provide resources such as the Civil Guard, the National Police, state health resources, or the Military Emergency Unit. The intervention of the UME does not necessarily mean that the central Government takes over the crisis: it can be deployed as support to the autonomous community.
The Law 17/2015 of the National Civil Protection System reserves to the Ministry of the Interior the possibility of declaring an emergency of national interest. This can occur when its effects affect several communities, require extraordinary state resources, or severely compromise essential services and goods of national interest. Only then does the direction pass to the State. The framework can be consulted in the consolidated text of the Civil Protection Law.
How an earthquake is managed from the first call to 112
The response begins when the IGN detects the earthquake and transmits its parameters to the emergency centers. At the same time, 112 receives calls from citizens and collects information about possible damages, injured persons, landslides, or service interruptions.
With that data, the Board determines whether to maintain enhanced surveillance or formally activate the autonomous plan. The municipalities then mobilize their services and communicate the incidents to regional coordination.
The technical teams first inspect the most sensitive points: hospitals, residences, schools, bridges, roads, water, electricity, and gas networks. Then, they review the buildings from which cracks, landslides, or other damages have been reported.
Management goes through five main phases:
- Detection and evaluation: the IGN analyzes the earthquake and 112 collects the incidents.
- Activation: the Board or the municipality activates the corresponding plan.
- Intervention: police, firefighters, medical personnel, and technicians are deployed.
- Stabilization: buildings are secured, services are restored, and evacuated people are attended to.
- Recovery: administrations assess the damages, process aid, and carry out repairs.
Prevention is also shared among administrations
Public policies against earthquakes are not limited to reacting after a shake. They also include the development of risk maps, emergency plans, drills, citizen information, and building regulations.
The State establishes the basic civil protection regulations and the general technical safety requirements for buildings. The autonomous communities develop territorial and special plans, coordinate emergency services, and can approve complementary regulations.
Municipalities transfer those obligations to the urban sphere through planning, licenses, urban discipline, and the maintenance of municipal buildings. Additionally, they must have local plans in those territories where seismic risk requires it.
This prevention is especially important in Granada, one of the areas with the highest seismic hazard in the Peninsula. The risk does not depend solely on the magnitude of an earthquake but also on its depth, proximity to populated areas, and the vulnerability of buildings.
Granada tests the system
The earthquake of magnitude 4.7 recorded this Tuesday has been followed by another of magnitude 4.0 south of Churriana de la Vega and by movements of magnitudes 2.8, 2.6, and 2.9 in the metropolitan area, according to the updated catalog of the IGN.
For the moment, there are no victims or new serious structural damages. As a preventive measure, the Metro de Granada has temporarily reduced the speed of circulation and municipal services are monitoring facades, cornices, and buildings that already had damage.
Thus, the State measures and provides support, the Junta directs the regional response, and the municipalities act on the ground. The command may change if the severity increases, but the competencies do not disappear: they are integrated under a common direction.
