From the start Tephrabase has included a mapping feature. In 1995, when Tephrabase was launched, we originally used the XeroxPARC Map Viewer for displaying the locations of sites. This early web mapping service was discontinued in the early 2000s. For several years Google Maps was the means of showing locations. Tephrabase now uses OpenLayers as its main mapping system, through which a variety of basemaps are available including Google and OpenStreetMaps. A variety of satellite images and maps are therefore available.. For example, if you search for all the sites where Hekla 4 is found, a location will be produced along with the other information.
