"Earthquake of magnitude 3.3 alerts residents of the Central Valley after evacuation drill."

In the early hours of Thursday, a magnitude 3.3 earthquake shook the tranquility of the Central Valley, leaving many residents on high alert. With its epicenter located in Coronado and a depth of 6 kilometers, the tremor was felt in various locations, particularly in San José, Heredia, and some areas of Cartago. This natural phenomenon occurred shortly after the National Evacuation Drill, designed to prepare the population for emergency situations, which left many feeling particularly uneasy as they experienced a real tremor. Marino Protti, a seismologist at the Costa Rican Volcanological and Seismological Observatory (OVSICORI), provided a detailed analysis of the event. According to Protti, while the magnitude of the earthquake was not alarming, the perception of its intensity was heightened due to its relatively shallow depth. Such small earthquakes can generate a significant sensation of movement in densely populated urban areas like San José. Reports from residents indicate that the tremor was felt strongly and quickly, eliciting varied reactions among the population. While some woke up startled, others chose to remain calm, recalling the lessons learned during the drill. The coincidence in timing of both events has led many to reflect on the importance of being prepared for emergency situations. The Seismological Institute also emphasized the usual nature of such movements in the region, which is located in a geologically active zone. However, a sense of insecurity persists among some citizens, who question the effectiveness of drills and overall preparedness for a potential higher-magnitude seismic event. For many, the earthquake served as a reminder of the reality of living in a country that, while beautiful, also faces significant natural risks. Authorities urge the population to take preventive measures seriously and to review their family evacuation plans, regardless of the magnitude of the earthquakes that occur. The event has also sparked a series of conversations on social media, where citizens share their experiences and advice on how to act in case of an earthquake. The community has shown active interest in seeking information and disseminating prevention messages, reflecting a growing concern for personal and collective safety. Additionally, Protti highlighted that, although this earthquake did not cause material damage or injuries, it is crucial for the population to remain calm and be prepared to act. The perception of an earthquake, even if mild, can generate panic, and it is essential to promote a culture of prevention and effective response to disasters. In the educational sphere, authorities have indicated that they will continue their training programs in seismic prevention, ensuring that both students and teachers are equipped to respond appropriately in emergencies. These initiatives aim to build a more resilient community aware of the risks it faces. As the response of the population is evaluated and data from the event is analyzed, OVSICORI will continue to monitor seismic activity in the region. The scientific community is also working on gathering information to better understand the phenomenon and, above all, to improve alert and communication systems for emergencies. In conclusion, while the 3.3 magnitude earthquake was not devastating, it served as an important reminder of Costa Rica's seismic vulnerability. Preparation and education are key tools to strengthen the capacity to respond to future events, and the collaboration of society as a whole will be essential to face the challenges that may arise in terms of seismic safety.
