4.7 Earthquake in Coquimbo raises concerns but tsunami risk is ruled out.

After 12:31 PM on Tuesday, a magnitude 4.7 earthquake shook the Coquimbo region in northern Chile. This seismic event was recorded 1.55 kilometers northwest of Fray Jorge Park in the municipality of Ovalle. The news has caused concern among the local population, although the Hydrographic and Oceanographic Service of the Navy (SHOA) has rushed to reassure the public, ruling out the possibility of a tsunami. SHOA, through its communication channels, emphasized that the earthquake did not have the necessary characteristics to trigger a tsunami along the Chilean coasts. This statement was supported by the National Disaster Prevention and Response Service (Senapred), which also used its social media platforms to inform about the situation, aiming to ease any fears that may have arisen among the area's residents. Earthquakes, natural phenomena that occur due to the movement of tectonic plates, are a constant reality in Chile, which is considered one of the most seismically active countries in the world. In this context, it is important to understand the difference between commonly used terms such as earthquake, tremor, and quake. According to the National Seismological Center, magnitude refers to the amount of energy released by an earthquake, while intensity describes the effects of that movement on people, structures, and the ground. In Chile, the Modified Mercalli Intensity Scale is used to classify the severity of tremors. This scale has twelve levels, allowing experts and the general population to understand the magnitude of the impact that a seismic event can have in different locations. For example, for an earthquake to be considered a quake, it must reach at least level VII on this scale, which implies significant structural damage. Although the recent earthquake in Coquimbo has not been classified as a destructive event, it serves as a reminder of the need for the population to be prepared and aware of the country's seismic nature. Local geology, building types, and distance from the epicenter are factors that can influence the intensity of the earthquake experienced in different areas, making each event unique in its manifestation. Despite the reassurance provided by SHOA, it is essential for citizens to maintain a mindset of prevention. Education on how to act during an earthquake, as well as preparing an emergency kit, are measures that can make a difference in the event of stronger tremors or larger-scale processes. The experience of living in a country with high seismic activity has also led Chile to develop more stringent building regulations and implement early warning systems. These efforts are a suitable response to the country's geological reality and aim to minimize damage and protect the population in case of emergencies. In conclusion, while the 4.7 earthquake in the Coquimbo region did not raise alarms about a possible tsunami, it serves as a reminder of the importance of being prepared and educated about these phenomena. Collaboration between institutions and timely communication are vital to ensure the safety of the population, and it is essential that each of us adopts a proactive approach to the possibility of future seismic events.
