Looking for maps? GIS data? Try the HVO publications page!

Many messages to AskHVO (askHVO@usgs.gov) request resources relating to geologic maps and geographic information systems (GIS) data. “Is there a map of a certain lava flow?” “Where can I find the associated GIS data?” All HVO and USGS publications are searchable at https://pubs.er.usgs.gov/, but this service is most effective if you already know what to look for.
