About Algar Seco: 4 Most Know Geological Facts

1. Prehistoric Underwater Formation:

Algar Seco, located on the southern coast of Portugal, was once submerged under the sea during the Miocene epoch, approximately 23 to 5 million years ago.

At that time, the Mediterranean region was largely arid, resembling a desert, while the Atlantic Ocean’s water levels were substantially higher, reaching about 20 meters above current levels.

2. Seismic Activity and Geological Shifts:

A significant seismic event occurred when a powerful earthquake struck the area around Gibraltar.

This seismic activity resulted in the rupture of the landmass at Gibraltar, allowing approximately 20 meters of the Atlantic Ocean’s water to rush into the Mediterranean Sea.

Scientists estimate that this dramatic event unfolded over a period of three to four weeks, reshaping the geography and hydrology of the region.

3. Limestone Composition and Vulnerability to Erosion

Algar Seco is primarily composed of carbonated massive rock known as limestone.

Limestone is particularly susceptible to erosion caused by various natural elements, including water, wind, and rain.

Over time, the continuous interaction between these elements and the limestone rock has sculpted the landscape of Algar Seco, shaping its distinctive features.

4. Creation of Karst Landscape:

The ongoing erosion processes, fueled by water, wind, and other environmental factors, have led to the formation of the stunning Karst landscape that characterises Algar Seco.

Karst landscapes are renowned for their unique geological formations, such as caves, sinkholes, and rugged cliffs, all of which contribute to the scenic beauty and geological intrigue of Algar Seco.

This tale not only enriches the visitor’s experience but also serves as a poignant reminder of the historical and cultural significance of this remarkable site.
