Like this Tsunami in Brazil? Wasn't Brazil free from Earthquakes and Tsunamis? Looks like no more! Check out this article and understand what is happening and why the Tsunami alert on the Brazilian coast is causing concern.
Recent news has caused some concern among residents of the coastal regions of the American continent. After all, there is a chance of a Tsunami that could affect the entire continent, with a greater impact on the North and Northeast regions of Brazil.
The warning about the possible Tsunami that could hit the entire coast of Brazil came through the authorities in Spain. The National Geographic Institute (IGN) of Spain reported seismic activities in the Canary Islands, more precisely in La Palma where the volcano is located. Cumbre Vieja.

Cumbre Vieja Volcano
The island of La Palma, where the Cumbre Vieja volcano is located, is a volcanic island, that is, born from volcanic activities. Cumbre Vieja is under constant monitoring by authorities as it is a volcano capable of causing a global catastrophe. Its last eruption was in 1971, and it has been inactive since then.
But recently, around 2 days ago, the volcano started to show seismic activity. What usually precedes an eruption. Which caused him to reach the surveillance state of Yellow level, 2nd of four stages (Green, Yellow, Orange and Red). Of these 3 being the third a high alert to precede an eruption, while the red one notifies an eruption already in progress.
Tsunami Risks
No need to worry, as much as there is a chance of a tsunami happening because of an eruption of this volcano, the chances are practically minimal. After all, that would only happen if the eruption happened a certain way. But there are several possibilities, including a sea eruption, below the earth, and magma not even reaching the surface.
For an eruption of Cumbre Vieja to cause a Tsunami in Brazil, it is necessary for it to cause a total collapse of the Volcano. With that, destabilizing the slope of the island, added to several other factors, would cause the extremely rare event, which so far has not been observed, which would generate the tsunami. See the statement by Mauro Gustavo Resse Filho, Geologist:
“It is estimated that the next eruption could destabilize the slope of the island due to factors such as the slope of the volcano, volume of material mobilized, climatic factors and mainly, to an existing zone of weakness that will facilitate the occurrence of mass movement”
“This movement, in turn, could be capable of generating a tsunami that will travel transatlantic distances and that will reach practically all the countries bathed by the Atlantic Ocean. From the modeling of such an event, information was obtained that the entire Brazilian coast will be affected.”

There is no reason to fear!
No, your Geography teacher was not wrong in saying that Brazil is “free” of such phenomena (Tsunami, Earthquakes...), after all, most of the time, they are caused by the Tectonic plates. But the possibility now of a tsunami affecting Brazil exists, however extremely low. After all, it would depend on a phenomenon, as stated above, never before recorded!
Everything that is known so far has been obtained through simulations. As accurate as they are, they observe all possible scenarios. That is, it is not given as something that will happen, but as one of the scenarios. Even if such a volcano becomes very active, it does not mean that there will be a tsunami here.
