The Invisible Eyes: Volcanic Lakes Near Managua

Illustration for: The Invisible Eyes: Volcanic Lakes Near Managua

These two ‘invisible’ eyes from ground level were formed as a result of a violent volcanic eruption thousands of years ago. This unusual scene, influenced by a precise optical illusion, cannot be fully discerned from ground level.

The peninsula, located about 16 kilometers (10 miles) northwest of Managua, was formed due to a series of volcanic explosions. During these eruptions, low-density materials like pumice are violently ejected from beneath the surface.

The smaller lake (on the left), which is about 1.1 miles (1.7 kilometers) wide, is situated within the crater of the Apoyeque volcano. The larger lake (on the right), known as Laguna de Xiloa, is about 1.5 miles (2.4 kilometers) wide at its broadest point.

When viewed from space, the lakes appear side by side. However, the surface of Lake Apoyeque is about 400 meters (1,300 feet) above sea level, while Lake Xiloa is near sea level, which means you can only see it if you stand at the edge of the Apoyeque crater.
