Hi,

I don't understand the elevation, see topomap (~550, not 585) and wikipedia https://cs.wikipedia.org/wiki/Chebsk%C3%A1_p%C3%A1nev (max=534)

I don't understand the position : according to wikipedia (cs and de versions), the Cheb basin is in Czech Republic, not in Germany (probably this explains the elevation problem).

Volcano, volcano:status and volcano: type seems not to be the best tagging, maybe place=region and region=volcano_field would be better, see https://en.wikipedia.org/wiki/Volcanic_field

Best regards
