Mapping poorly studied and remote volcanoes will be made much easier with data from ASTER and MISR on the EOS
AM-1 platform. We can start this process using multispectral data from the SPOT spacecraft, which
provides 20 m/pixel resolution. This slide shows the north rift zone of Karthala volcano, which is
in the Grand Comoro Islands, which are in the Indian Ocean between Africa and Madagascar. Notice
all of the cinder cones along the rift zone.
EOS activities
Organize and publish background information on volcanoes
from different parts of the world; especially Africa. Fill in gaps in our knowledge of the
eruptive history of volcanoes. Document eruption history, rock types, landforms, style of
volcanism, existence of geologic maps, and existing satellite images.
