BRAZIL: Meteorological Tsunami Wave Hit Santa Catarina Lagoon Coast. Hmm... They Say Meteorological Tsunamis Stem From Atmospheric Disturbances Not Seismic Activities.

GlobalAwareness101 published Meteorological Tsunami Wave Hit Brazil Coast. Hmm... they say meteorological tsunamis stem from atmospheric disturbances not seismic activities. Didn't know this could happen.
Canal UOL published November 12, 2023: Tsunami meteorológico em Laguna: câmeras flagram avanço do mar; veja vídeo. As câmeras de segurança de um estabelecimento flagraram o tsunami meteorológico atingindo a praia do Cardoso em Laguna, em Santa Catarina. O mar avança rapidamente e arrasta vários carros que estão na areia e chega a invadir o comércio.

Interesting that I could not find any news channel other than this BNN news reporting in print and neither could I find any news channel reporting in video other than local Brazilian news sources and a few other latin American channels. I thought this was important information that needed to be shared because I did't know tsunamis could be caused by "atmospheric disturbances". That's questionable and raising a few red flags for me.

A stark illustration of the unpredictability of natural disasters unfolded recently at Cardoso Beach, Santa Catarina, Brazil, where a meteorological tsunami rattled the coastal community. This rare phenomenon, different from the typically earthquake-induced tsunamis, is triggered by atmospheric instability, such as storms, making its occurrence hard to forecast and prepare for. The aftermath saw vehicles being swept away by the forceful waves, but thankfully, no injuries were reported. This event underscores the need for heightened awareness and effective risk mitigation strategies.

Challenging the Norms: Meteorological Tsunamis

Unlike their seismic counterparts, meteorological tsunamis are born out of atmospheric disturbances, making them a potent force to reckon with due to their unpredictability. The recent event in Santa Catarina brought this reality to light, causing large waves that dragged parked cars into the sea. The sight of vehicles being whisked away by the powerful tide, captured and shared on social media, highlighted the intensity of this rare natural phenomenon.

Call for Enhanced Awareness and Preparedness

Incidents like the one at Cardoso Beach bring to fore the need for bolstering awareness, preparedness, and risk mitigation strategies for meteorological tsunamis. The lack of established protocols to address such events underscores the importance of advancing scientific understanding and developing tailored early warning systems to tackle these unique types of natural hazards.

Convergence of Extreme Weather Events

Simultaneously, the National Institute of Meteorology issued a red heat alert for six states and the Federal District in Brazil, indicating temperatures expected to be 5oC above average. This, coupled with the meteorological tsunami, highlights the intricate and multifaceted challenges innate to climate-related issues. The unpredictable combination of atmospheric instability, intense storms, and temperature fluctuations stresses the need for comprehensive and adaptive strategies for climate resilience and disaster preparedness.

Looking Ahead: Collaborative Risk Management

In the face of evolving climate-related challenges, it becomes increasingly vital for all stakeholders – government agencies, meteorological institutes, and local communities – to collaborate on comprehensive risk communication and preparedness initiatives. This includes raising public awareness about meteorological tsunamis, developing tailored response protocols, and integrating early warning systems into existing disaster management frameworks. As we grapple with the convergence of extreme weather events, it becomes clear that a holistic approach to climate adaptation and disaster risk reduction is essential.
