Group: Natural

How to Map

Add the natural=volcano as a node . Place it as close to the centre of the main crater/caldera/vent as you can.

Name the volcano using name=* on the node.

Tags to use in combination

volcano:status=* - Status of the Volcano
- volcano:status=active - active
- volcano:status=dormant - dormant (the volcano was active in historical times)
- volcano:status=extinct - extinct (the volcano has not erupted in recorded history) - However, a feature should not be tagged as a volcano if this status lacks Verifiability: there should be a crater, lava plug or other evidence of an extinct volcanic vent.
volcano:type=* - Volcano type
- volcano:type=stratovolcano - Stratovolcano on Wikipedia
- volcano:type=shield - Shield volcano on Wikipedia
- volcano:type=scoria - Volcanic cone on Wikipedia

These are the three main types. Further information in Volcano on Wikipedia

ele=* - Height of a volcano in meters in relation to the sea level

Relation to `natural=peak`

Note although many volcanoes are mountains and in many maps natural=volcano and natural=peak are rendered in a similar way the location of the main volcanic vent/crater is generally not identical to the highest peak so natural=volcano does not necessarily imply a mountain peak.

Crater rim

The crater rim can be tagged using

natural=cliff or natural=ridge depending on the shape of the crater plus
geological=volcanic_caldera_rim to indicate that it is a volcanic crater/caldera rim

natural=crater has been used to map crater and bomb crater rims, areas or impact sites but has never been defined, use is discouraged until there is some definition.
