Living next to a volcano

Fifty-one active volcanoes along the arc, each with hazard rings sized by the reach of its plausible eruptions — click a volcano for its eruptive history.

Volcano attributes from the Smithsonian Global Volcanism Program; hazard rings and population estimates by the NIKA team. Basemap © CARTO, © OpenStreetMap contributors.

Replicate this export

Open the QGIS project download in QGIS 3.44 or newer, choose Web → QGIS2WebMap by NIKA → Create web map, and set the options below — the basemap and relief live in the dialog, not the project file. Everything not listed stays at its default.

Map tab · Basemap

Current canvas view (frame Java, or the whole arc)

Run these yourself

The project download is a small zip with the .qgz, its data and a README with each map’s dialog settings. Open it in QGIS 3.44 or newer and export it through Web → QGIS2WebMap by NIKA — you get the same file that is on stage. The maps fetch basemap tiles at view time; the sharing guide explains what an export contains.
