Geological Formation: A Volcanic Legacy

The St. Peter and St. Paul Archipelago’s existence is a direct result of volcanic activity along the Mid-Atlantic Ridge, a tectonic plate boundary where the South American and African plates are slowly drifting apart. Millions of years of volcanic eruptions, both submarine and subaerial, have built up these islands from the ocean floor. The archipelago comprises eleven small islets and rocks, the largest being São Pedro (St. Peter), which is only about 800 meters long. These islands are essentially the tips of massive submarine volcanic structures, remnants of a fiery past.

The Impact of Volcanic Activity:

The volcanic activity shaping the archipelago continues to influence its landscape. While major eruptions are infrequent, the islands' rocky surfaces are constantly being sculpted by erosion, including relentless wave action, wind, and the occasional tremor. This dynamic interaction between geological processes and environmental forces creates a visually striking and geologically significant site. The presence of various volcanic rock types, such as basalt and scoria, provides further evidence of the complex volcanic history of this unique location.
