Summary:

Approximately 450 out of 560 historically active volcanoes around the world are poorly known and irregularly monitored. While most of these volcanoes are located in developing countries, the remoteness or difficult field conditions that surround the volcanoes, (such as dense tropical forests, high elevations, or dissected terrains), makes it difficult to collect field data or to produce accurate and detailed topographic datasets that are essential for evaluating and modelling volcanic hazards. This article explains how Advanced Spaceborne Thermal Emission and Reflective Radiometer (ASTER) and Shuttle Radar Topography Mission (SRTM) are used to produce digital elevation models (DEMs) and remote sensing datasets in an effort to obtain information that is essential for analyzing volcano morphology worldwide for active volcanoes such as Mauna Kea, Hawaii and Oldoinyo Lengai, Tanzania.
