"Volcanoes of the World" is a database describing the physical characteristics of Holocene volcanoes and their eruptions. This search returns a list of volcano names which may be filtered based on location (set using a map), country, volcano name, population within various distance ranges, rock types, and types of volcanic features. Name and country searches will also return subfeature names. If map, population, rock type, or features filters are used, only primary volcano names will be returned. Results may be downloaded into an Excel spreadsheet.
