"Alert issued about tsunami risk in Chile following 7.1 earthquake in Japan."

The recent warning of a potential "megathrust earthquake" in Japan, following a 7.1 magnitude earthquake on the Richter scale, has raised alarms both in Japan and in Chile, where experts are warning about the possible repercussions of a tsunami. In an exclusive conversation with the program "Buenos Días a Todos," geophysicist Cristián Farías from the Catholic University of Temuco provided a detailed analysis of how a tsunami in Japan could affect the Chilean coasts. The Japan Meteorological Agency has alerted the public, stating that while the likelihood of a major earthquake is higher than normal, the imminence of a devastating seismic event cannot be confirmed with certainty. Such warnings have become more frequent since the devastating earthquake of 2011, which led to the Fukushima nuclear accident, prompting authorities to implement a new alert system. This historical context has provided lessons on how to prevent and respond to disasters of this magnitude. Farías emphasized the relationship between both countries in the context of tsunamis, noting that geography and tectonic activity make Japan and Chile "curious neighbors," sharing the experience of being both sources and recipients of tsunamis. In his statements, he stressed that a possible megathrust earthquake in Japan could trigger a tsunami that would travel across the Pacific Ocean, significantly impacting the Chilean coasts. The geophysicist warned that while the entire Chilean coastline would be exposed, the most vulnerable areas are located in the central part of the country. Bays such as Dichato and Talcahuano, due to their particular shape, could experience amplified waves, making these areas critical when anticipating the arrival of a tsunami. "These bays are places where tsunami waves can be amplified, and that's where we need to focus," Farías emphasized. The expert also mentioned that in the event of a catastrophic occurrence, Chile would have an estimated 20 hours to prepare. This provides a considerable margin for activating emergency protocols, evacuations, and other safety measures. Responding to a tsunami requires effective coordination, and this time could be crucial for saving lives. Additionally, Farías highlighted the work of the Hydrographic and Oceanographic Service of the Navy (SHOA), which has significantly advanced in monitoring the sea since 2010. This progress means that the country is better prepared to detect seismic movements in the ocean and respond promptly to the arrival of a tsunami. Investment in monitoring technology and personnel training has been key to improving the country's response capability. The concern over a potential tsunami is not unfounded, considering the seismic history of both countries. Chile has been the site of several devastating earthquakes, and previous experience in disaster management is an aspect that should not be underestimated. The population must be informed and educated about safety measures and protocols to follow in the event of such an occurrence. In conclusion, the possibility of a tsunami generated by a megathrust earthquake in Japan serves as a reminder of the geological interconnectedness between Pacific countries. Preparation, education, and constant monitoring are key tools to mitigate the impact of these natural disasters. With accumulated experience and technological advancements, Chile is in a better position to face potential emergencies, though it must never let its guard down against the forces of nature. History has shown that being prepared is essential to protect the population and minimize damage from a destructive phenomenon like a tsunami.
