This ERS-2 radar image shows the central part of the Ecuadorian highlands,
part of the mountain chains that run north-south along
the Pacific front of the Americas.
Their formation is the result of the westward drift of the
continent and its collision with oceanic plates of the earth's crust.
The consequences of this drift are not only an
uplift of the land mass but also intense
fracturing, which gives rise to volcanic
activity and also results
in catastrophic earthquakes.
The image reveals the morphology of
three clearly distinct sections.
To the right (east) the relief is
rather smooth and in effect consists of old metamorphic rocks.
The central part consists of the Inner-Andes Depression or Graben,
mainly flat land, and to the west,
a much finer drainage pattern with sharper
crests eroded into mainly sedimentary rocks can be perceived.
Details of Quito, Ecuador's capital, the Guayllabamba watershed,
the Andean lakes of Cuicocha and San Pablo, the town of Ibarra and
the Imbabura and Cayambe volcanoes can be viewed by clicking on the
