The federal wildfire occurrence database lists 18 fires within 5 miles of Vulcan between 1993 and 2020, burning about 38 acres in total. None started naturally. 2 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Wellsville
• Hillcrest
• Spring Grove
• Walkers
• East Liverpool
• Jethro

Every fire recorded in Columbiana County

Museums hold 384 specimens collected within 10 miles of Vulcan between 1889 and 1975: 271 Animalia, 99 Plantae, 14 Fungi. 12 distinct Species records are shown. Collected by A. D. Mac Gillivroy, Albert Peyron, Athearn, Herbert D. and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

The federal mineral resources record lists 4 workings within 5 miles of Vulcan: 3 past producers, 1 producer. 1 still produces. What was taken out: Clay, Fire Clay (Refractory). Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
