+/- natural=volcano Description Used to mark a volcano.

A volcano is an opening exposed on the earth's surface where volcanic material is emitted. All volcanoes contain a central vent underlying the summit crater of the volcano. Some volcanos may have more than one vent, fissures and fumeroles.

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.

Optionally you can also add other information:

• status=active, status=dormant, status=extinct

Classifying a volcano as active, dormant, or extinct is a subjective and inexact exercise. Active resembles currently erupting or exhibiting unrest through earthquakes, uplift, and/or new gas emissions. An inactive volcano is generally considered dormant if it has erupted in historic time. This definition, however, is rather ambiguous and not scientific, because recorded history varies from thousands of years in Europe and the Middle East, to only a few hundred years in other regions of the world, like the Pacific Northwest of the United States.

• type=stratovolcano, type=shield, type=scoria

These are the three main types of volcano. More information can be found here: http://www.geology.sdsu.edu/how_volcanoes_work/Volcano_types.html

• ele=*

Tag the highest point of the volcano as a number in metres.

• is_in=*

This is useful for search engines and constructing gazeteers. You can use the is_in tag to show which country it is in. You might also want to show that it is part of an administrative state or county and a geographic place such as an island or sea.

is_in=Sunda Strait, Indonesia

or better:

is_in:state=Bandar Lampung
is_in:ocean=Pacific Ocean
is_in:country=Indonesia
is_in:country_code=ID

Example

natural=volcano
name=Anak Krakatau
alt_name=Krakatoa
type=stratovolcano
status=active
ele=200
is_in:ocean=Pacific Ocean
is_in:country_code=ID
is_in:state=Bandar Lampung
