Public data

Volcanos

A free, ready-to-attach connector serving the Smithsonian Global Volcanism Program catalog — volcanoes, eruptions, and types — as clean SQL tables.

Stable Free By Query.Farm Python worker

Overview

What Volcanos does

The Volcanos connector wraps the Smithsonian Global Volcanism Program data into an attachable SQL catalog. Query volcanoes by region, type, and last-known eruption without scraping or downloading anything yourself.

It is the reference worker behind several Query.Farm VGI examples and is free to attach. Use it to learn the Orchard workflow or to practice geospatial joins against other public datasets.

Highlights

  • Smithsonian volcano catalog as tables
  • Eruption history and volcano types
  • Latitude / longitude ready for geospatial joins
  • No token required — free to attach
  • Backs the Query.Farm VGI demos
