A rare and deadly weather event has struck the coast of Argentina, claiming one life and leaving dozens injured. A powerful meteotsunami, a wave driven by rapid changes in air pressure, crashed into beaches in the resort area of Santa Clara del Mar on Monday, catching sunbathers completely by surprise.
Sudden Surge and Tragic Consequences
The event unfolded with terrifying speed. A wall of water, estimated to be up to 30 feet (approximately 9 metres) high, surged onto the coastline without warning. Holidaymakers were forced to scramble for safety as the powerful wave swept through the popular beach area.
The incident resulted in one fatality. Yair Manno, a 29-year-old man from Mar del Plata who was on holiday, was killed after being pulled out to sea by the force of the water. Reports confirm he tragically struck his head on rocks. In addition to this loss, at least 35 people sustained injuries during the chaotic event.
What is a Meteotsunami?
This disaster was caused by a meteotsunami, a phenomenon distinct from the more commonly known seismic tsunamis. Unlike traditional tsunamis, which are triggered by underwater earthquakes or volcanic eruptions, meteotsunamis are generated by sudden changes in atmospheric pressure, often associated with fast-moving weather events like squalls or thunderstorms.
These pressure disturbances can force the water below to move, creating a wave that amplifies as it approaches the shore. They can occur in any coastal region and, as seen in Argentina, can be just as destructive as their seismic counterparts, despite often having a more localised impact.
Aftermath and Wider Implications
The aftermath in Santa Clara del Mar has been one of shock and recovery. Emergency services responded swiftly to treat the injured and secure the area. The event serves as a stark reminder of the powerful and sometimes unexpected forces of nature that can affect coastal communities globally.
While this specific tragedy occurred in Argentina, it highlights the importance of monitoring for such atmospheric conditions worldwide. Understanding and improving early warning systems for meteotsunamis remains a critical challenge for meteorologists and coastal safety authorities to prevent future loss of life.
