What the record says

NCEI’s account, from the sources it cites.

Reference #13945:

Although the tsunami-like waves of this event were not comparably high, they were superimposed to an important storm surge, causing a cumulative hazardous event and considerable material losses. Moreover, they occurred during the carnival holidays, when beaches were crowded, creating dangerous situations. Fortunately, no deaths or serious injuries were reported.

This storm surge was generated by an intense subtropical cyclone that passed over the region in the previous days.

Photographs […] illustrate hazardous effects of the waves impacting the beach; the images were extracted from an Internet video. The wave trough caused a long and evident retreat of the sea level, while the wave crest initiated the beach inundation up to the sea wall.

Every runup
