Introduction

The youngest (but pre-historic) eruption from Rota produced thick andesitic lava flows from a NE-trending fissure NW of the summit. 2 small lava domes, El Bosque (also known as Lomas San Ignacio del Bosque or Cerro Ojochal) are located on the plain 2 km north of the flank of Rota, and are aligned NNW-SSE on the same direction as many other eruptive fissures, which are transverse to the Marrabios Range volcanoes. Near Rota volcano is a large field of lava flows erupted from numerous small cones and maars.

Rota Photos

The smooth crust of the lake is broken into plates, which are moving against or away from each other, simulating plate tectonics. Above, a miniature mid-ocean spreading zone can be seen where two larger pieces of crust are moving away from each other. Even miniature transform faults and sheer zones due to differential and rotational movements can be seen. (Photo: Tom Pfeiffer)
